How to Master Mars in Dota 2: The Ultimate Guide for Every Rank (2026)

Why Mars Is the Ultimate Teamfight Initiator

Mars occupies a unique space in Dota 2 as an offlaner who can single-handedly win team fights with one well-placed ultimate. Unlike most initiators who rely on Blink Dagger and a single stun, Mars brings a full package: a long-range impale, a massive AoE knockback, passive damage reduction from the front, and an arena that traps enemies inside while blocking projectiles from outside. That combination makes him one of the most self-sufficient offlaners in the game.

In the current meta, Mars sits at around a 50-51% winrate across all ranks according to Dotabuff, with his winrate climbing significantly in Ancient and above where players understand proper Arena placement. His pick rate remains consistently high — he is one of the top 10 most picked offlaners in pub games globally, and he sees regular appearances in professional matches.

What makes Mars special is his versatility in team compositions. He works with wombo-combo lineups (Arena + any AoE damage), he works as a solo initiator, and he even functions as a mid-game carry with the right items. His Bulwark passive makes him deceptively tanky from the front, meaning he can manfight most carries in the early and mid game. If you want to climb MMR through sheer impact on team fights, Mars is one of the best heroes in the game to learn.

Abilities Deep Dive

Spear of Mars (Q)

Mars hurls his legendary spear forward in a line, damaging the first enemy hero hit and pushing them back. If the target is pushed into a tree, cliff, or building, they are impaled and stunned for 2.0/2.4/2.8/3.2 seconds. The spear travels 900 units and deals 100/175/250/325 damage.

The hidden power of Spear is in the impale interaction. The stun duration is massive at max level — 3.2 seconds is longer than most ultimates in the game. But the key mechanic that separates good Mars players from great ones is understanding exactly what surfaces count for impale. Trees, buildings, and cliffs all work. But importantly, Arena of Blood walls also count as an impale surface. This means a Spear into your own Arena wall guarantees the full stun duration every time, no tree hunting required.

Another detail most players miss: Spear hits the first unit in its path, including creeps if you are not careful. In lane, always position yourself so there are no creeps between you and the enemy hero before throwing. The spear also provides vision along its travel path, which makes it useful for scouting Roshan pit or checking high ground.

God’s Rebuke (W)

Mars smashes enemies in a cone in front of him with his shield, dealing critical damage based on his attack and knocking them back. The crit multiplier is 160%/200%/240%/280% and it has a 14/12/10/8 second cooldown. God’s Rebuke applies attack modifiers, which is a crucial interaction.

Because it applies attack modifiers, items like Desolator, Skull Basher, and even Satanic lifesteal all proc on God’s Rebuke. This is what enables Mars to transition into a semi-carry in the mid game. A level 4 God’s Rebuke with Desolator can chunk a support for 60-70% of their health in a single ability.

The knockback component is equally important. You can use God’s Rebuke to push enemies into your Spear line, push them into Arena walls for Spear impales, or simply reposition enemies in team fights. The ability also hits all units in the cone, making it an excellent farming tool. One common pattern in lane is to use God’s Rebuke on the ranged creep to secure the last hit while simultaneously harassing the enemy hero standing behind it.

Bulwark (E)

Mars’ passive ability reduces damage he takes from the front and sides. At max level, it blocks 70% of damage from attacks that hit the front 240-degree arc. This is not just physical damage — Bulwark reduces all attack damage from the front, making Mars incredibly durable when facing enemies head-on.

The active component of Bulwark is equally powerful. When activated, Mars braces behind his shield, redirecting nearby enemy attacks to himself and gaining bonus damage reduction. This makes Bulwark active an incredible tool for protecting your carry in team fights. If an enemy right-click carry is hitting your pos 1, activating Bulwark near them forces those attacks onto Mars instead, who reduces the damage significantly.

A critical detail: Bulwark does NOT reduce spell damage. Magic nukers like Lina, Zeus, and Skywrath Mage completely ignore Bulwark. This is Mars’ primary weakness — he is tanky against right-clickers but vulnerable to burst magic damage from behind or from spells.

Arena of Blood (R)

Mars’ signature ultimate summons a circular arena of spectral spear-wielding soldiers. The arena lasts 5/6/7 seconds and has a 500 radius. Enemies inside the arena cannot leave — they are knocked back if they try to cross the boundary. Enemies outside cannot enter. Most importantly, the arena blocks all projectiles from crossing the boundary in either direction.

The soldiers on the arena wall also attack enemies who stand near the edge, dealing 50/75/100 damage per hit on a 1-second interval. This damage is often underestimated — an enemy pressed against the Arena wall takes consistent DPS that adds up quickly, especially with the multiple soldiers hitting simultaneously.

Key Arena interactions that every Mars player must know:

• Spear into Arena wall = guaranteed impale stun. This is the bread-and-butter combo.
• Force Staff works through Arena walls. Enemies with Force Staff can escape, and you can Force allies in or out.
• BKB does NOT let you walk through Arena walls. Magic immunity prevents the wall damage but not the physical barrier effect.
• Certain movement abilities bypass Arena: Blink, Pounce, Leap, and most teleportation abilities go through it.
• Arena blocks projectiles like Sniper ult, Zeus bolt, and basic attacks from crossing the boundary, making it a defensive tool as well.

Skill Build Order

Standard Offlane maxes God’s Rebuke first for farming efficiency and lane harass, taking a value point in Spear at level 2 for kill potential. Kill Lane maxes Spear first when you have a lane partner with reliable setup (like a Tusk or Shadow Shaman support). Survivability build prioritizes Bulwark early when facing heavy harassment from dual ranged lanes.

Item Builds by Rank

Mars item builds vary significantly by rank because lower-rank games are longer and messier, while higher-rank games demand efficient timing windows. Here is the definitive breakdown:

Why Items Differ by Rank

Herald-Crusader: Games tend to go longer, so building Desolator as a core timing works well because you will have extended team fights where the extra damage matters. Refresher Orb is devastating at these ranks because enemies rarely have Force Staffs or BKBs to deal with double Arena.

Archon-Legend: Players start understanding timings, so getting Blink + BKB online before 25 minutes is critical. Desolator becomes a third item because you need the damage to stay relevant. Overwhelming Blink is the luxury upgrade that adds a slow to your initiation.

Ancient-Divine: At these ranks, the game is decided in key team fights around 20-35 minutes. Blink + BKB is non-negotiable. Coaching from Immortal players consistently emphasizes that Mars needs to hit this timing to be effective. Aghanim’s Scepter becomes an option because it adds extra soldiers to Arena and increases the damage output significantly.

Immortal: Build is hyper-optimized. Blink + BKB is the bare minimum. Refresher is the single most impactful item because double Arena in a team fight is almost always a won fight. Satanic provides massive sustain with God’s Rebuke lifesteal interaction — one W on a clumped group heals Mars to full.

Situational Items Worth Knowing

• Heaven’s Halberd: Against right-click carries who do not build BKB early (Huskar, Ursa). The evasion also synergizes with Bulwark.
• Lotus Orb: Defensive option when your team lacks dispel. Purges silences off yourself before initiating.
• Pipe of Insight: When facing heavy magic damage lineups (Zeus, Leshrac, Pugna). Mars is naturally weak to magic damage.
• Blade Mail: Budget option in lower ranks. Works well with Bulwark active to reflect damage while tanking.
• Aghanim’s Shard: Adds God’s Rebuke auto-attacks during Arena. Solid DPS increase when you can afford it after core items.

Laning Phase Masterclass

Mars is one of the strongest laners among offlaners. His combination of God’s Rebuke harass, Bulwark damage reduction, and Spear kill threat makes him a nightmare for most safe lane duos. Understanding how to leverage these strengths is the difference between winning and losing your lane.

Levels 1-3: Establishing Dominance

Start with God’s Rebuke at level 1. Use it to secure ranged creep last hits while simultaneously hitting the enemy carry. Position yourself so the cone of God’s Rebuke covers both the ranged creep and the hero. At 160% crit damage, even at level 1, this chunks squishy carries for a noticeable amount.

At level 2, take Spear. Now you have kill threat. If the enemy carry walks near a tree line, a Spear into tree impale is 2.0 seconds of stun plus 100 damage. Follow up with God’s Rebuke and right-clicks. Communicate with your support to chain their disable after the Spear stun. First blood on Mars at level 2 is extremely common.

At level 3, your second point in God’s Rebuke brings the crit to 200% and the cooldown to 12 seconds. This is your primary farming and harass tool. Use it on cooldown to push the wave when you want to pull the lane, or to secure multiple last hits under tower.

Levels 4-6: Kill Timing and Lane Control

Level 4 is when you take your first point in Bulwark. This is a massive power spike in lane — you suddenly take 25% less damage from the front. Trade aggressively by walking up to the enemy carry, tanking their hits while facing them, and using God’s Rebuke on cooldown. Most carries cannot out-trade a Mars with Bulwark active.

Level 6 with Arena changes the lane dynamic completely. If you have Phase Boots and Soul Ring by this point (you should), a single Arena + Spear into Arena wall combo is almost always a kill. The full combo:

1. Walk up or use Phase Boots for extra speed
2. Cast Arena on the enemy (try to center it so they are near a wall)
3. Immediately Spear them into the Arena wall for the guaranteed impale
4. God’s Rebuke while they are stunned
5. Right-click to finish

Lane Partner Synergies

Mars works with nearly any support, but some combinations are especially deadly:

• Tusk: Snowball into Ice Shards sets up perfect Spear impales. One of the strongest kill lanes in the game.
• Shadow Shaman: Shackles guarantee Spear timing, and Mass Serpent Wards inside Arena is devastating.
• Witch Doctor: Maledict inside Arena is borderline unfair. The target cannot escape the damage amplification.
• Grimstroke: Ink Swell on Mars as he initiates, plus Soulbind inside Arena forces double Spear stuns.
• Undying: Tombstone inside Arena forces enemies to deal with zombies while trapped. Decay stacks make Mars even tankier.

Dealing with Hard Lanes

Against ranged dual lanes (like Drow + Vengeful Spirit), Mars struggles before Bulwark. Play passively for levels 1-3, use God’s Rebuke to secure last hits from maximum range, and pull the small camp to keep the wave near your tower. Once you hit level 4 with Bulwark, you can start trading again.

Against heavy magic damage lanes (like Skywrath + any carry), consider taking Bulwark at level 2 instead of Spear. Magic damage ignores Bulwark, but the reduced attack damage still helps. Buy extra regen and focus on getting levels. Mars scales better than most offlaners — a rough lane does not ruin your game as long as you hit level 6 with Soul Ring.

Mid and Late Game Transitions

Mars’ mid-game timing is one of the most well-defined in Dota 2. Your power peaks at Blink Dagger + BKB + level 12-15, which typically happens around the 20-25 minute mark. This is when you should be forcing fights at every opportunity.

The 15-25 Minute Window: Peak Aggression

Once you have Blink Dagger, your initiation range jumps from “walk up and Arena” to “Blink from fog into perfect Arena placement.” The difference is massive. A Blink Arena catches enemies before they can react, while walking up gives them time to spread out or pre-cast defensive abilities.

The standard team fight initiation sequence:

1. Identify the target cluster — you want at least 2-3 heroes inside Arena
2. Blink into the center of the cluster
3. Immediately cast Arena — do not right-click or hesitate
4. Spear the highest priority target into the Arena wall
5. BKB so you cannot be stunned during follow-up
6. God’s Rebuke the clumped enemies for massive AoE damage
7. Right-click the Spear-stunned target to finish them

The key mistake most players make is using BKB before Arena. If you BKB first, you telegraph your initiation and enemies scatter. Arena first, then BKB to protect yourself inside the Arena while you deal damage.

Team Fight Positioning

Mars is a frontline initiator, not a follow-up fighter. Your job is to create the fight, not join it. Position in fog, look for clusters of enemies near objectives (Roshan, towers, runes), and Blink in when your team is ready to follow. A common mistake is using Arena defensively to protect your carry — while this can work, it wastes Mars’ biggest strength as an initiator.

After your initial combo, face the enemy carry to maximize Bulwark damage reduction. Mars is incredibly hard to kill from the front, so positioning yourself between the enemy damage dealers and your backline is ideal. Use God’s Rebuke on cooldown for damage and knockback utility.

Late Game (35+ Minutes)

Mars does fall off relative to hard carries in the ultra-late game, but with the right items, he remains relevant. Refresher Orb is the single best late-game item because double Arena back-to-back is 12-14 seconds of team fight control. Very few heroes can survive two consecutive Arena + Spear combos.

In the late game, your role shifts slightly from initiator to fight controller. Use Arena to zone enemies during Roshan fights (cast it around Roshan pit entrance), use it to trap enemies during high ground pushes, and use it defensively to protect your team when sieging.

If the game goes extremely late (50+ minutes), consider selling Blink for Overwhelming Blink for the AoE slow, or picking up Satanic for the God’s Rebuke lifesteal interaction. A full-slotted Mars with Overwhelm Blink, BKB, Refresher, Desolator, Satanic, and Assault Cuirass can legitimately manfight most carries inside Arena.

Counters: Heroes That Destroy Mars

Understanding Mars’ weaknesses is just as important as knowing his strengths. These five heroes consistently give Mars the hardest time:

1. Lifestealer

Lifestealer is Mars’ worst nightmare. Rage provides magic immunity that does not care about Arena walls (he can Rage and walk right through them since BKB piercing abilities ignore the barrier), and his percentage-based lifesteal means he out-sustains Mars in any prolonged fight. Feast damage also shreds Mars’ large HP pool. If the enemy picks Lifestealer, consider playing more as a team fighter and less as a duelist.

How to play around it: Never Arena a Lifestealer alone. He will Rage through the wall and chase you down. Instead, use Arena to trap his teammates while your team kites Lifestealer outside. Focus your Spear on other targets.

2. Juggernaut

Juggernaut counters Mars hard because Blade Fury makes him magic immune (bypassing Arena walls) and Omnislash ignores Bulwark since it hits from all angles simultaneously. Spin + TP also means he can escape Arena easily. The matchup is frustrating at every stage of the game.

How to play around it: Wait for Juggernaut to use Blade Fury before casting Arena. His spin has a 26-second cooldown at level 1 — if he spins to farm, that is your window. Also, Heaven’s Halberd is excellent here since he cannot attack during disarm.

3. Phantom Lancer

Phantom Lancer overwhelms Mars with illusions. Arena catches one PL but he Doppelganges out while his army shreds Mars from multiple angles (bypassing Bulwark). Mars cannot effectively target the real PL in a sea of illusions, and God’s Rebuke hitting all of them means wasted damage on fake copies.

How to play around it: Build Shiva’s Guard for the aura damage that reveals real PL, and focus Arena on his supports instead. Crimson Guard is also strong against illusion swarm.

4. Ursa

Ursa’s Enrage reduces all incoming damage including God’s Rebuke, and his Fury Swipes stack faster than Mars can handle. Ursa also builds BKB in nearly every game, which means he pops BKB + Enrage and simply walks through Arena to maul Mars. The close-range nature of both heroes means Bulwark is partially effective, but Ursa’s burst is usually too much.

How to play around it: Heaven’s Halberd is mandatory. Disarm Ursa before he stacks Fury Swipes. Also, do not try to 1v1 him — use Arena to trap Ursa’s team and let your carry deal with the bear.

5. Enigma

Enigma is a counter not because he beats Mars in lane, but because Black Hole inside Arena is game-ending for Mars’ team. If you Arena and your team jumps in, Enigma Blink + Black Hole catches everyone in a neat package. The threat of Black Hole also means Mars has to wait for Enigma to show before committing Arena, which delays initiation and loses tempo.

How to play around it: Save Arena until after Enigma uses Black Hole. If you catch Enigma inside Arena before he channels, Spear him into the wall to interrupt. Always check for Enigma positioning before blinking in.

Heroes Mars Destroys

Mars is equally devastating against certain hero archetypes. These are the matchups where picking Mars is practically a free win:

1. Sniper

Sniper is the classic Mars victim. Arena blocks all of Sniper’s attacks and abilities from outside, while trapping him inside with a hero who has massive burst damage. Sniper has zero mobility to escape Arena (no blink, no leap), and his entire kit relies on range that Arena nullifies. Every time you see a Sniper pick, Mars becomes a top-3 counter-pick.

2. Drow Ranger

Drow Ranger suffers the same fate as Sniper but even worse. Her Marksmanship bonus is disabled when Mars is close (melee range removes the agility bonus), and Arena blocks her Frost Arrows from outside while trapping her inside where she is weakest. Gust cannot save her once Arena is up.

3. Zeus

While Zeus deals magic damage (which ignores Bulwark), Arena blocks Lightning Bolt and Arc Lightning projectiles from crossing the boundary. This means Zeus cannot nuke targets inside Arena from outside. Combine this with the fact that Zeus has no mobility to escape Arena, and the God of Thunder gets humiliated by the God of War.

4. Shadow Fiend

Shadow Fiend is squishy, immobile, and relies on standing still to cast Requiem of Souls. Arena + Spear interrupts Requiem and traps SF inside where his low HP pool makes him an easy kill. SF also loses souls on death, making Mars kills extra punishing.

5. Crystal Maiden

Crystal Maiden inside Arena is the definition of a bad time. She is slow, fragile, and her Freezing Field channel gets interrupted by Spear. She cannot escape Arena without Force Staff, and even then, the knockback mechanic pushes her back inside. CM is one of the easiest heroes for Mars to kill at every stage of the game.

How Pros Play Mars in the Current Patch

Mars remains a staple in professional Dota 2. In recent tournaments throughout 2025 and early 2026, Mars has seen consistent picks across regions, particularly in the offlane position 3 role. Here is what the best players in the world are doing differently:

Build Trends

Professional Mars players have shifted toward a faster BKB timing compared to previous patches. The current pro build is Phase Boots into Soul Ring into Blink Dagger into immediate BKB. Desolator has moved from a core item to a luxury pickup because pro games are faster and Mars needs to be team fight ready by 20 minutes.

Several top offlaners have been building Aghanim’s Scepter as a second or third item after Blink + BKB. The extra Arena soldiers and increased duration make it an incredible team fight upgrade that scales better than Desolator in coordinated play.

Arena Placement Philosophy

Pro players use Arena very differently than pub players. Instead of trying to catch all five enemies, pros focus on isolating 2-3 key targets — usually the enemy mid and one support. The goal is not a five-man Arena (that rarely happens against coordinated teams) but rather separating the enemy carry from their supports and burst damage. A 2-man Arena that catches the right targets is worth more than a 4-man Arena that catches the wrong ones.

Another pro technique is using Arena defensively on Roshan. When their team is taking Roshan, Mars places Arena on the pit entrance, blocking all projectiles from entering while their team finishes the kill. This forces enemies to either walk through the Arena (getting stunned and damaged) or wait until it expires, giving Mars’ team a free Roshan.

Notable Pro Players on Mars

Players like Collapse (Team Spirit) and Faith_bian have showcased Mars at the highest level. Collapse’s Arena placements at TI are legendary — his ability to find 3-4 man Arenas from fog consistently is a masterclass in positioning and patience. Watch replays of these players to understand the tempo and decision-making of a professional Mars.

Rank-Specific Climbing Guide

Herald to Guardian: Building the Foundation

At this rank, the most important thing is not dying. Mars is naturally tanky, so use that to your advantage. Focus on these fundamentals:

• Last hitting with God’s Rebuke: Use W on the ranged creep every wave. This alone will double your farm compared to only right-clicking.
• Simple combos: Arena on top of someone, then Spear them into the Arena wall. Do not worry about complex setups — the basic combo kills most heroes at this rank.
• Buy Blink Dagger: At Herald-Guardian, many offlaners skip Blink. Do not skip it. The difference in initiation is enormous.
• Push lanes after kills: After winning a team fight, hit the tower. Mars can tank tower shots easily with Bulwark facing the tower.

Your goal at this rank is to average 6+ kills, fewer than 5 deaths, and 350+ GPM. If you can do that consistently on Mars, you will climb out of Herald-Guardian within 50 games.

Crusader to Archon: Adding Game Sense

At Crusader-Archon, you need to start thinking about when to fight and when to farm. Mars is not a hero who afk-farms jungle — he wants to be active on the map creating pressure. Key improvements:

• Smoke ganks: Buy smokes and organize ganks on the enemy mid or carry. Mars + 1 support with a smoke is usually enough for a kill with Arena + Spear.
• Stacking camps: Before your Soul Ring timing, stack the large camp near your offlane tower. One God’s Rebuke clears a stacked camp, accelerating your Blink timing.
• Objective focus: After hitting level 6, always be looking for tower pushes after successful fights. Mars pushes towers faster than most offlaners thanks to God’s Rebuke damage on the tower.
• Spear accuracy: Practice throwing Spear near tree lines. At this rank, improving your impale accuracy from 40% to 70% is a massive power increase.

Legend to Ancient: The Macro Leap

Legend-Ancient is where Mars players need to understand the macro game. You are no longer just fighting — you are controlling the map:

• Split pushing: Mars clears waves instantly with God’s Rebuke. Push out dangerous lanes that your carry cannot safely farm, then TP to fights.
• Roshan timing: Mars is one of the best Roshan fighters because Arena on Roshan pit controls the entire area. Take Roshan after winning a team fight or killing 2+ enemies.
• BKB timing: At Legend+, enemies start buying stuns and disables specifically for you. BKB before your second or third major fight is critical. Do not greed for Desolator over BKB.
• Reading the map: Before blinking in, check where all five enemy heroes are. If you cannot see the enemy Invoker or Faceless Void, they might be waiting to counter-initiate your Arena.

If you are stuck at Legend and want to hit Ancient, professional coaching can accelerate your understanding of macro play significantly. Many players plateau here because they have good mechanics but lack game sense.

Divine to Immortal: What Separates the Top 1%

At Divine and above, every Mars player knows the combos. What separates Immortal Mars players is decision-making and timing:

• Arena economy: Do not use Arena on cooldown. Wait for the perfect fight. One Arena in a key team fight is worth more than three random Arenas that catch one support each.
• Spear angle manipulation: Position yourself so the enemy has trees behind them before throwing Spear. Walk to create the angle rather than throwing from wherever you are standing.
• Bulwark toggling: Toggle Bulwark active during fights to redirect attacks to yourself, protecting your carry. This is a micro-intensive technique that requires tracking who the enemy is attacking.
• Itemization reading: Check enemy inventories before fighting. If the enemy carry has Satanic + BKB, do not Arena them — Arena their supports instead and let your team kite the carry.
• Refresher timing: Double Arena is the single most powerful team fight tool in the game. The first Arena zones and baits BKBs. The second Arena, cast immediately after the first expires, catches enemies with BKB on cooldown. This sequence wins games at every rank.

Tips and Tricks

Animation Cancels and Hidden Mechanics

• Spear + God’s Rebuke instant combo: You can cast God’s Rebuke during the Spear throw animation. This means the Rebuke knockback can push the enemy into the Spear path for a guaranteed hit. The timing is tight but devastating when mastered.
• Arena cancel: If you misplace Arena, you can immediately Spear to reposition the fight. A “bad” Arena can still be salvaged by Spearing a priority target into whatever wall section is closest to them.
• Phase Boots timing: Use Phase Boots before Spear for the added damage on the Spear hit. The Phase buff applies to the Spear projectile damage calculation.
• God’s Rebuke farming pattern: In jungle, position yourself between two camps and use God’s Rebuke to hit creeps from both simultaneously. This nearly doubles your farming speed.

Common Mistakes to Avoid

• Arena then BKB order: Never BKB before Arena. It wastes precious BKB duration on the travel time and telegraphs your initiation. Arena first, then BKB.
• Spearing creeps in lane: Spear hits the FIRST unit. Always check your creep positioning before throwing. One misplaced ranged creep ruins your kill attempt.
• Bulwark facing: Mars players often forget to face the damage source. After casting abilities, turn Mars to face the enemy carry. This alone can reduce incoming damage by 70%.
• Greeding for multi-hero Arenas: A 2-man Arena on the right targets beats a 5-man Arena attempt that whiffs. Throw Arena when you have a clear catch, not when you hope everyone walks into range.
• Ignoring Spear tree setup: Before fights, use a Quelling Blade to cut specific trees that create impale angles. This is a high-level technique that creates kill opportunities where none existed.

Advanced Techniques

• Double Spear with Refresher: Cast Arena, Spear target into wall, Refresher, cast second Arena immediately as first expires, Spear a second target. This creates 6+ seconds of continuous control.
• Arena as Roshan zone: Stand inside Roshan pit and cast Arena centered on the entrance. Your team can safely kill Roshan while the Arena blocks all incoming projectiles and prevents enemies from walking in.
• God’s Rebuke into cliff: Near certain cliff edges, God’s Rebuke knockback can push enemies onto cliffs, stranding them without TP. Works near the secret shops and certain jungle cliff faces.
• Bulwark active as a “taunt”: In team fights, activate Bulwark near your carry when the enemy right-click hero is hitting them. The redirect forces attacks onto Mars, who reduces the damage. This is like a budget Axe Berserker’s Call without the disable.
