Bad against...[]

Axe icon.png
Lifestealer icon.png
  • Rage, acting as a pseudo-Black King Bar icon.png Black King Bar, completely negates Mars' initiation if used in time.
  • Feast does damage and heals based on max health, perfect against high-health strength heroes like Mars.
  • Infest allows Lifestealer to potentially save allies from Mars' initiation with a quick burst of extra health.
Riki icon.png
Batrider icon.png
  • Sticky Napalm slows turn rate, making it difficult for Mars to control the direction he is facing to activate Bulwark.
  • Flaming Lasso disables Mars while enemies re-position themselves behind Mars to avoid Bulwark.
Faceless Void icon.png
  • Time Walk allows Faceless Void to escape or enter Arena Of Blood, and helps him recover from Mars' burst damage.
  • Time Lock's magical damage ignores Bulwark.
  • Chronosphere allows Faceless Void to reposition behind Mars, ignoring his Bulwark while he is helplessly frozen in time.
Huskar icon.png
  • Burning Spear's magical damage is very troublesome for Mars in the laning stage.
  • Life Break's percentage-based magical damage bypasses Bulwark, and can also be used to jump in or out of Arena Of Blood.
Lina icon.png
Necrophos icon.png
  • Necrophos' largely magical damage completely ignores Bulwark.
  • Ghost Shroud protects Necrophos from God's Rebuke but more importantly stops Mars from being a threat in lane.
Ogre Magi icon.png
  • Mars has no way to trade with Ogre Magi in the early game thanks to his high base health, resistance and Ignite.
  • Once Ogre Magi gets level 2 he may also have Bloodlust, which makes him even harder to deal with in lane.
  • Fireblast can be ridiculously strong later on in the game for controlling Mars.
  • Spear of Mars, which is Mars' main source of damage in the early game, cannot guarantee kills early on Ogre Magi.
Outworld Destroyer icon.png
Pugna icon.png
  • Nether Blast, Decrepify and Life Drain deal high magical damage and bypasses Bulwark.
  • Nether Ward reduces the amount of abilities Mars can use during fights and forces Mars to be careful about the heavy mana cost of Arena Of Blood.
  • Pugna is one of few heroes that can contest Mars' ability to push and defend towers early on.
Pangolier icon.png
  • Swashbuckle is an auto attack and therefore ignores Mars' Bulwark.
  • Shield Crash upgraded with Aghanim is an auto attack and therefore ignores Mars' Bulwark.
  • Rolling Thunder makes him immune to magic, making Pangolier able to roll in and out from Mars' Arena Of Blood.
Shadow Fiend icon.png
  • If Mars lanes middle, Shadow Fiend can keep the lane pushed against him.
  • Shadow Fiend can go an entirely magical based build, which is very effective against Mars.
Storm Spirit icon.png
  • Ball Lightning makes it almost impossible to catch Storm Spirit without someone else initiating for you.
  • Overload is not reduced by Bulwark and the magical damage spam can wear down Mars quickly.
Underlord icon.png
  • Firestorm and Pit of Malice are very disruptive in team fights, completely matching Mars especially since it can all be cast inside Arena Of Blood and also does percentage-based magical damage, negating Bulwark.
  • Dark Rift can save any allies of Underlord trapped in Arena Of Blood.
  • Atrophy Aura allows Underlord to lane against Mars quite well since he does not have the best base damage during the early game.
  • Underlord is a common carrier of both Pipe of Insight icon.png Pipe of Insight and Mekansm icon.png Mekansm/Guardian Greaves icon.png Guardian Greaves, allowing his team to combat Mars in the mid to late game.
Undying icon.png
  • Decay, Soul Rip and Flesh Golem all deal magical damage which ignores Bulwark.
  • Decay reduces Mars' natural strength and therefore his health pool, which is what he relies on to trade effectively in lane.
Venomancer icon.png
  • Venomancer's spells all deal magical damage, ignoring Bulwark.
  • Venomancer's multiple slows are especially effective at kiting Mars.
  • Lua error in Module:Ability_ID at line 61: Could not find Cargo data for "Plague Wards". can attack through Arena Of Blood.
Viper icon.png
Tusk icon.png
  • Snowball can protect Tusk and his teammates from a Spear of Mars stun after an Arena of Blood, and with proper targeting, even bring them out of the Arena. This is especially noticeable in the earlier stages of the game before allies buy Black King Bar icon.png Black King Bar and rely on this less. Even during the late-game, Tusk can purchase a Blink Dagger icon.png Blink Dagger to save allies that are caught before Black King Bars can be used by Blinking in and Snowballing out.
  • Tag Team is a constant threat to Mars in-lane, as even with early Bulwark points it deal so much damage and slow that Mars is forced to back off from the lane and play defensively every time the spell is used.
    • Worth noting is that Ice Shards can be detrimental to Tusk's own team by creating terrain that Spear of Mars can latch on, though using it conservatively is a good enough solution in most cases.
Zeus icon.png
  • Mars' own father is a formidable foe because Zeus deals massive amounts of magical damage. The high damage, low cooldown nukes of Arc Lightning and Lightning Bolt combined with the percent health magic damage of Static Field will shred Mars' health because it bypasses Bulwark completely.



Good against...[]

Bloodseeker icon.png
  • Arena Of Blood prevents Bloodseeker from attacking a Ruptured target.
  • Bulwark helps Mars survive Rupture ganks simply by turning towards Bloodseeker without moving.
  • Spear of Mars and God's Rebuke can push Bloodseeker from Ruptured targets.
Juggernaut icon.png
  • Juggernaut deals mostly physical damage, which is easily mitigated with Bulwark.
  • Juggernaut's Omnislash switches to opposite directions which each slash, so Mars can mitigate most of its damage since he only takes full damage from one direction: his back.
Legion Commander icon.png
  • Bulwark prevents Legion Commander from gaining wins with Duel.
Phantom Assassin icon.png
  • Phantom Assassin's high physical damage is greatly reduced by Bulwark.
  • God's Rebuke has true strike, ignoring the evasion from Blur.
Slark icon.png
  • Bulwark blocks much of Slark's basic attack damage, even during Shadow Dance.
  • Slark finds it very difficult to have a good early/mid game when pressured in the early game by Spear of Mars and God's Rebuke.
  • Spear of Mars and God's Rebuke can hit Slark through Shadow Dance.
  • Should Pounce be on cooldown, Slark is very vulnerable inside Arena of Blood.
Spectre icon.png
  • Spectre cannot have a good game if she is pressured heavily in lane, which is something Mars can do.
  • Spectre can use Haunt and Spectral Dagger inside and outside from Arena of Blood, but it doesn't really matter since Mars does best during the early and mid game.
  • Should Spectre get to the late game, Mars can block a large amount of her damage and split the teamfights in his advantage.
Terrorblade icon.png
  • Bulwark negates most of the physical damage from Terrorblade and his illusions.
  • Mars' AoE abilities kill Terrorblade's illusions quickly.
Weaver icon.png
  • Shukuchi cannot help Weaver escape from Arena of Blood, so with vision, Weaver is an easy kill.
  • Time Lapse will also not save Weaver in a large amount of situations inside Arena of Blood, especially if he's pinned to the walls with Spear of Mars.
  • The Swarm and Geminate Attack is not very useful against a hero that can tank 70% of his main damage source.


Works well with...[]

Dark Seer icon.png
Huskar icon.png
  • Due to how Berserker's Blood works, it makes it very ideal for Huskar when allies can separate heroes like Mars can.
  • Huskar can push enemies into the Arena of Blood corners with Inner Fire.
  • Huskar can also get large amounts of Burning Spear stacks very quickly if enemies are trapped in Arena of Blood.
Crystal Maiden icon.png
Disruptor icon.png
Keeper of the Light icon.png
  • Chakra Magic helps with Mars' low mana pool.
  • Blinding Light knocks enemies into Arena of Blood's walls.
  • Arena Of Blood allows Keeper of the Light to easily hit enemies with Illuminate.
Kunkka icon.png
  • Torrent and Ghostship are easy to land against enemies trapped in Arena Of Blood.
Lich icon.png
  • Frost Shield allows Mars to tank even more damage with Bulwark.
  • Arena Of Blood keeps heroes closer together for more guaranteed Chain Frost bounces.
Monkey King icon.png
Phoenix icon.png
  • Supernova and Sun Ray work well on enemies trapped inside Arena Of Blood.
  • A well-placed Arena Of Blood can also protect Phoenix's Supernova from both melee and ranged attacks.
Riki icon.png
Sven icon.png
  • Sven's Storm Hammer can prolong the stun from Spear of Mars.
  • Warcry's shield enhances Mars' already impressive durability against physical attacks, making him nearly unkillable in team fights.
  • Arena Of Blood will help Sven catch an easy target with his Great Cleave and God's Strength.
