Kingdom Rush 6 Tier List – Best Heroes

AshbiteFlying area damage · True damage · Control

Best for: Crowded lanes, flexible damage coverage

Key abilities: Blazing Breath · Searing Sneeze · Feeding Time · Spitfire · Melting Fury · Wildfire Barrage

Synergy: Keep enemies in the flames with Knights Order, Gerald, or Royal Catapult’s Tarred Zone.

Unlock: 84 stars

• A large health pool, wide fire attacks, and true damage make Ashbite a remarkably forgiving damage pick. Blazing Breath and Wildfire Barrage hit packs without asking for a perfect single-target setup.
• Searing Sneeze gives the damage time to work by stunning a group for two seconds. Spitfire adds a burn to basic attacks, so even periods between bigger skills keep applying pressure.
• Feeding Time is the trickier part of the kit: landing gives Ashbite heavy bites and a heal on a kill, but moving cancels it. Use it at a held choke rather than chasing one runner across the map.
• Melting Fury rewards sustained burns against armored enemies. Ashbite earns S tier through reach, crowd control, and raw output; the main tradeoff is that a flying hero cannot substitute for a dependable ground blocker.

IgnusMobile brawler · True damage · Area clearing

Best for: Armored waves, clustered enemies

Key abilities: Fireball · Heat Wave · Flame Rush · Melting Core · Reverse Entropy · Supernova

Synergy: Pair with Gerald, Rhodes, or another durable blocker to keep enemies near his damage aura.

Unlock: 58 stars

• Almost every meaningful hit bypasses armor. Fireball handles a priority target, Heat Wave catches the crowd around Ignus, and Flame Rush carries damage across multiple enemies.
• Melting Core keeps hurting enemies that stay close. When blockers hold a pack in place, Supernova has the space and time to land its full true-damage burst.
• Reverse Entropy restores 15% of his maximum health whenever he uses a skill. That gives an otherwise unarmored frontliner a strong recovery loop, especially alongside cooldown reduction.
• He still needs sensible placement: pushing an armorless melee hero into an isolated elite before his healing triggers is asking for a respawn. Flight over long distances helps him return to the useful lane.

DrakkanArcane area damage · Silence · Summons

Best for: Caster-heavy waves, wide-map support

Key abilities: Nullifying Pulse · Deconstruct · Double Dragon · Arcane Affinity · Arcane Storm

Synergy: Pair with a physical-damage hero or Marksman towers against magic-resistant waves.

Unlock: 80 stars

• Nullifying Pulse silences enemies for eight seconds while hitting an area. Shutting down dangerous enemy abilities can save more lives than a larger damage number would.
• Double Dragon supplies another body in the fight, while Arcane Storm threatens enemies across the battlefield. Base-damage area and skill-damage nodes reinforce a strong crowd-clearing kit.
• The tree offers 100% magic resistance and another 20% skill cooldown reduction through Arcane Affinity. Together with his high health rating, those are unusually strong tools against magic-heavy stages.
• His listed attack speed is slow and much of his offense is magical. Physical or true-damage backup matters when enemies resist magic, but his control and coverage still make him an exceptional first pick.

OniMelee duelist · True damage · Armor shred

Best for: Elites, armored targets, tough single lanes

Key abilities: Death Strike · Netherfocus · Hellish Blink · Lethal Combo · Duel Fervor · Sword Torment

Synergy: Keep a blocker or area-damage tower nearby so Oni can concentrate on dangerous targets.

Unlock: 70 stars

• Death Strike deals true damage to a single target, and Hellish Blink jumps to a leading enemy for three hits with permanent armor reduction. He is built to make a high-priority target disappear.
• Lethal Combo adds a stronger follow-up basic attack after skill use. Duel Fervor then rewards him for holding the same enemy by healing from his attacks; Netherfocus adds recovery when his health drops.
• Sword Torment gives him a needed area hit, but his strongest routine is still focused on one enemy. A lane full of small enemies calls for artillery or an area-focused partner.
• Oni sits near the top of A because his elite damage and sustain are excellent, while his narrower coverage makes him a specialist compared with the S-tier wave clearers.

Gerald LightseekerFrontline blocker · Ally defense · Survival

Best for: Holding chokepoints, protecting allied units

Key abilities: Inspire Courage · Shield of Retribution · Fated Survivor · Hardened Steel · Battle Vigor · Divine Blade

Synergy: Put barracks and a damage-heavy tower behind his defensive line.

• Inspire Courage boosts nearby units’ armor, making Gerald especially useful at a barracks choke. He improves the whole hold rather than relying on his modest personal damage rating.
• Shield of Retribution adds armor and reflects melee hits. Hardened Steel can block melee attacks, and Battle Vigor regenerates health while he is blocking: a strong combination when a lane stays busy.
• Fated Survivor can avert a lethal hit and push back the attacker. Divine Blade adds true damage and a brief area stun, so he has an answer when a dangerous enemy threatens to break the line.
• He lacks the reach and fast wave clear of the S-tier damage heroes. On a stage where enemies spend little time in melee with him, his defensive investments deliver less value.

ZefiraMagic support · Resistance shred · Mobile control

Best for: Magic-heavy loadouts, concentrated kill zones

Key abilities: Dazzling Hammer · Shielding Blades · Astral Blink · Weakening Aura · Ethereal Spears

Synergy: Keep her near Scholar Mage, Light Priestess, or another tower attacking the same targets.

• Weakening Aura lowers nearby enemy resistances by 30%. In a crowded magic kill zone, that is a team-wide damage tool rather than a perk for Zefira alone.
• Dazzling Hammer stuns a group, and Ethereal Spears punishes enemies gathered on the path. Those tools make her useful even when her basic damage rating looks unimpressive.
• Astral Blink covers long rotations and gives her a short damage boost afterward. Shielding Blades adds protection, but her very low health still punishes careless positioning.
• Her A-tier ceiling depends on staying near enemies and the towers that exploit her debuff. A magic-resistant wave needs a broader damage mix even after resistance reduction.

GeminaIllusion summons · Multi-target blocking · Magic damage

Best for: Splitting pressure across several enemies

Key abilities: Forward Illusion · Guarding Decoy · Mirror Slashes · Solid Light · Last Effort · I Am Legion

Synergy: Hold illusions inside Royal Catapult or Scholar Mage coverage.

Unlock: 54 stars

• Forward Illusion creates a blocker, while Guarding Decoy leaves another when Gemina dodges an attack. Extra bodies can buy tower shots across several small fights at once.
• Mirror Slashes attacks through Gemina and her active illusions. Solid Light keeps the copies around longer, and Last Effort turns their deaths into area damage instead of a clean loss.
• I Am Legion pushes damage down the path and spawns up to three more illusions. With cooldown reduction, she can keep a messy wave occupied without personally tanking it.
• Her own health is low and she has no armor. The strength of this kit depends on the illusions staying relevant and in position; treat her as a flexible distraction specialist, not a durable solo anchor.

RhodesArmored tank · Crowd-control immunity · True damage

Best for: Holding dangerous lanes, resisting disruption

Key abilities: Sunbeam · Strong Crust · Twisting Top · Impervious · Unstoppable · Solar Flare

Synergy: Keep enemies in Solar Flare’s path with barracks or another strong blocker.

Unlock: 40 stars

• Strong Crust restores a chunk of health and adds armor, while Impervious improves armor at high health. This is a tank that can recover and keep occupying a contested lane.
• Unstoppable prevents stuns and slows from shutting down his positioning. Twisting Top brings its own slow, giving nearby towers more time against a pack.
• Sunbeam supplies early true damage. Solar Flare is the real payoff: a moving beam with substantial true damage per second when it lines up with enemies travelling the path.
• He trades some of the broad coverage of higher-tier picks for durability and an excellent beam angle. The exact number of Solar Flare hits on a moving wave will depend on the lane layout.

IllianaRanged support · Armor shred · Stun

Best for: Armored packs, ranged pressure

Key abilities: Tag! · Glitter Bomb · Easy Prey · Elvish Nimbleness · Airborne Bliss · Sparky, Incinerate!

Synergy: Combine her armor reduction with Archer Garrison, Sentry Watchtower, or another physical hitter.

Unlock: 66 stars

• Tag! bounces true damage between enemies and reduces armor. The armor shred makes nearby physical towers and her own attacks better against tougher packs.
• Glitter Bomb stuns a group for two seconds, setting up Easy Prey’s dive against a stunned target. That gives her more than one way to contribute while towers fire.
• Airborne Bliss doubles basic-attack damage while she is flying. Sparky, Incinerate! adds true-damage patches along the path, rewarding careful placement over a busy stretch.
• Her tiny health rating and lack of armor leave little room for bad positioning, despite her melee dodge chance. She is a strong ranged partner; bring someone else to hold the line.

MalikHeavy blocker · Stun · Area melee

Best for: Dense ground waves, stopping an elite advance

Key abilities: Unbreakable · Earthquake · Obliterate · Foehammer · Hammernado

Synergy: Position at a choke where artillery can keep hitting the enemies he gathers.

Unlock: 28 stars

• The highest health rating among the ground-focused tanks here gives Malik room to hold a lane. Unbreakable scales its shield with the blocked enemy’s health, making a large target valuable to him.
• Earthquake stuns an area for two seconds. Foehammer extends his basic attacks to nearby enemies, while Hammernado slows and damages a pack that stays in reach.
• Obliterate can remove a target from the map after a brief charge. That is potentially huge against troublesome enemies, though boss interactions need testing before counting on an instant removal.
• No innate armor and a low damage rating make him less self-sufficient than his health bar suggests. The Lone Wulf damage bonus also conflicts with parking him beside allied blockers, so pick his position deliberately.

ConnorMelee bruiser · Counterattack · Comeback burst

Best for: Holding a contested lane, burst at low health

Key abilities: Arterial Slash · Retribution · Earthshatter · Battleborn · Holy Grail · Templar Rage

Synergy: Give him healing or another blocker so his offensive windows last.

• Arterial Slash hits around him and adds true damage over time, while Retribution blocks the next melee hit before answering with a heavy strike. He wants to stay close to enemies.
• Earthshatter adds path coverage, and Templar Rage brings a stun plus a substantial ten-second boost to damage, speed, and movement. His peak can absolutely swing a crowded fight.
• Holy Grail revives him with 70% health, but its 180-second interval means it cannot carry every wave. Battleborn’s extra skill damage only applies below 40% health, a risky range to rely on.
• His moderate defenses and melee dependence make him less consistent than the A-tier anchors. The recorded Arterial Slash and Retribution values are level III, so their larger numbers should not be compared directly with level-I skills on other heroes.

BolinRanged artillery · Mines · Anti-armor

Best for: Predictable chokepoints, supporting a blocker

Key abilities: Smoke Mortar · Mine Field · Giant Slayer · Explosive Rounds · Sharpened Rounds · Suppressive Fire

Synergy: Use Gerald, Rhodes, or barracks to hold enemies inside smoke and near mines.

• Smoke Mortar slows a group, while Mine Field can stack traps along a predictable route. He is strongest when the enemy walks into an area prepared in advance.
• Sharpened Rounds ignores part of enemy armor, Explosive Rounds adds periodic splash, and Suppressive Fire supplies concentrated shots when a wave closes in.
• Giant Slayer adds damage based on enemy health, but the effect is explicitly reduced against bosses. Avoid treating the tooltip’s percentage as unrestricted boss damage.
• His very slow listed attack speed and low health and armor punish bad positioning. Smoke Mortar and Mine Field are recorded at level III; their numbers are not a fair one-to-one comparison with the other heroes’ level-I skills.
