Cillian: The Zombie Samurai That Just Won't Stay Dead
Overview
Meet Cillian, the "Undying" member of the Slayers of Fell Shadows family. Released back in the ancient times of 2021, this 4-star Fire Fighter was designed to be a persistent nuisance. He's a slow-starting engine that, if left unchecked, becomes a self-healing, mana-generating machine. While he doesn't have a costume to freshen up his wardrobe or stats, his base kit offers a unique mix of damage and survivability that can still find a home in specific niches today.

Hero Art & Visuals
Cillian sports a look that can best be described as "undead ronin meets European drifter." Heβs got the dual-wielding stance of a samurai, the pale, cracked skin of someone who's seen the other side of the grave, and a red scarf that screams "anime protagonist." It's a gritty, dark aesthetic that fits the "Fell Shadows" theme perfectly. One community reviewer famously pointed out his "shitty shoes," proving that even when you're immortal, comfortable footwear is hard to find.

Hero Stats
Base Stats (No Emblems)
| Level | Attack | Defense | Health | πͺPower |
|---|---|---|---|---|
4/70 | 631 | 682 | 1292 | 677 |
4/75lb1 | 685 | 741 | 1403 | 728 |
4/80lb2 | 795 | 859 | 1627 | 831 |
Let's address the elephant in the room: Cillian's stats are showing their age.
- Power: At 677, he is vastly behind modern 4-star constructs and toons which push near 800.
- Attack: 631 is low. For comparison, modern 4-star attackers sit comfortably above 800.
- Survivability: His defense and health are decent for his era but paper-thin against modern snipers who can deal 500%+ damage.
- Verdict: Without Limit Breaks (LB1 and LB2), he will melt. Even with LB2, his stats barely catch up to a non-limit-broken modern 4-star. You play him for the mechanic, not the muscle.
Special Skill: Reanimated Spite

Reanimated Spite
- Deals 315% damage to the target and nearby enemies.
- If the caster dies during the next 4 turns they are resurrected in the beginning of their next turn with 27% health. All status effects and stacks are removed when the caster dies.
- Stack (Max: 10): The caster gets +5% mana generation.
- Stack +2 (Max: 10): The caster recovers 20 HP each turn.
Reanimated Spite is a skill that tries to do two things: hurt the enemy and cheat death.
- The Damage: 315% to three targets is a respectable multiplier. It's not a team-wiper, but it softens up the field significantly.
- The Resurrection: This is his signature move. If Cillian dies within 4 turns of casting this, he comes back with 27% health. This creates a "damned if you do, damned if you don't" scenario for the opponent. Do they kill him now and trigger the revive, or let him live and keep generating stacks?
The synergy with his Fighter Class is hilarious. He can revive from his special skill, and if that fails (or expires), he can revive from his talent grid. He is the cockroach of Empires & Puzzlesβin the best way possible.
By the Numbers
- Mana Speed: Slow. He needs 12 tiles to fire initially.
- The Slayer Acceleration:
- 0 Stacks: 12 tiles (Slow).
- 5 Stacks (+25% Gen): ~9.6 tiles.
- 10 Stacks (+50% Gen): ~8 tiles (Functional Fast speed).
- Note: He needs to survive long enough to build these stacks. In modern fast-paced metas, this is his biggest hurdle.
- Damage Potential: With ~631 Attack, a 315% hit deals roughly 1987 raw damage (before defense). Against modern 4-stars with ~800 Defense, expect hits in the 300-400 range per target. It's chip damage by today's standards, but dangerous if he fires repeatedly.
Family Bonus, Passives, Aether Power & Unique Abilities
The Slayer family is all about the long game. They punish you for not killing them quickly, but Cillian punishes you for killing him.
Family Bonus

Challenge Festival II - Slayers
- Bonus for 1/2/3 Heroes:
- * 50%/75%/100% chance to receive the following stacks at the end of each turn:
- * Stack (Max: 10): The caster recovers 15 HP each turn.
- * Stack (Max: 10): The caster gets +6% mana generation.
- The members of this family have additional perks in the Challenge Festival events.
The Slayer Stack is one of the most powerful self-buffs in the game.
- Mana Generation: Caps at +50%. This transforms him from a Slow clunker into a rapid-fire machine.
- Healing: Caps at 100 HP per turn. This is passive regeneration that works even in "Bloody Battle" tournaments (though it won't heal, the stack still applies). Correction: In Bloody Battle, healing is 0, so the HP stack does nothing, but the Mana stack is gold.
Passives
Passive Skills
Resist Damage from Status EffectsThis character has innate resistance against incoming damage from status effects.
Resist Damage from Status Effects: -50% damage from Burns, Poisons, and Bleeds. This is surprisingly relevant against heroes like Colen or Proteus in 4-star tournaments, letting Cillian shrug off the worst of the attrition damage.
Aether Power

Attack Up
At the start of each battle, this Hero gets 20% attack for 6 turns
Attack Up: A simple flat boost. It helps his direct damage, which he desperately needs given his low base attack stat.
Legacy & Modern Relevance
- Historical Context: Upon release, Cillian was a "4-Star All-Star." He was a staple in Rush Attack tournaments and a nightmare on defense because of the revive loop.
- Power Creep Analysis: The game has gotten faster and hits harder. Waiting for Slow mana is a death sentence in many raids. His damage, once threatening, is now merely annoying.
- Modern Viability Verdict:
- Standard Raids: Bench. Too slow, too squishy.
- Rush Attack Tournaments: Viable. Set to Very Fast, he bypasses his slow start. The revive makes him a pain to clear from the tank or flank position.
- Bloody Battle: Niche Viable. His revive brings him back with HP, which is one of the few ways to "heal" in this mode (since it's a resurrection, not a heal, though the mechanism is distinct). Plus, his fighter talent works here too.
Emblem Path Analysis
You have two distinct ways to build Cillian, and both are valid depending on where you use him.
The Undying Tank (Defense Bias)
- Path: Defense > Health > Attack
- Pros: Maximizes his chance to survive until he casts his special. Increases the HP he has upon reviving (since 27% of a bigger pool is more HP).
- Cons: His hit becomes negligible, serving only to refresh his revive buff.
The Vengeful Spirit (Attack Bias) - Recommended
- Path: Attack > Defense > Health
- Pros: Squeezes every ounce of damage out of his 315% hit. Since he revives anyway, you might as well make him hurt when he's alive.
- Cons: Dies faster... but that's kind of his thing?
Final Recommendation
For most players, the Attack Path is recommended. If you are using Cillian in 2026, you likely need him to finish off enemies in Rush tournaments. A wet noodle hit won't help you there.
Strengths
- Double Resurrection: Combining his special skill with the Fighter class talent makes him incredibly sticky.
- Self-Sustain: Once the Slayer stacks get rolling, the passive healing (outside of Bloody Battle) makes him hard to wear down.
- Rush Attack King: Becomes a monster when his mana speed is fixed to Very Fast.
Weaknesses
- Glacial Start: Without Rush rules, he is painfully slow to get going.
- Vulnerable to Dispel: His resurrection is a buff. If a dispeller like Sabina or Caedmon hits him, he stays dead.
- Outdated Stats: He is fragile by modern standards and relies heavily on Limit Breaking to survive a single hit from a modern sniper.
Best Game Modes
- Rush Attack Tournaments (4-Star): This is his home. Put him on Flank or Wing and watch him outlast the enemy team.
- Faction Wars: Useful depth hero for "Undead" or "Slayer" themed restrictions if they arise.
- Map Stages: The self-healing and mana stacks make him great for long, drawn-out boss fights in Tower events.
Advanced Strategy & Team Compositions
Sample Team Ideas
- The "Walking Dead" Defense (Rush):
- Boldtusk - Cillian - Colen - Cillian - Kelile
- Why: A wall of Fighters. Revive talents everywhere. Cillian protects himself with his own revive while Boldtusk keeps the team topped up.
- The Slayer Family Stack:
- Cillian + Aodhan + Orla
- Why: Ensures the Family Bonus triggers 100% of the time, guaranteeing mana and health stacks every turn. This creates a snowball effect that is hard to stop if not dispelled immediately.
Counters & Anti-Synergies
- Dispellers: Sonya, Caedmon, and Sabina are his worst enemies. They wipe his revive buff and his Slayer stacks.
- Blockers: Proteus or Hel stop him from gaining the mana he desperately needs.
- Minion Munchers: Not directly a counter, but heroes like Captain of Diamonds don't care about his revive if they just keep eating his team.
Advice for New Players
If you pull Cillian early, he is a fantastic carry for map stages. His self-healing saves you potions, and his revive saves you gems. Level him up, but prioritize his emblems only if you lack faster 4-star reds like Scarlett or Kelile.
Advice for Veterans
Cillian is a "fun" project, not a meta one. If you have excess Fighter emblems and want a nuisance for your 4-star Rush defense team, he's worth a look. Do not use Alpha Aethers on him unless you are absolutely dedicated to the Slayer aesthetic. There are far better targets for those precious resources.
Community Corner: Hot Takes & History
The community has always had a soft spot for "The Undying."
- "Resurrection City": One content creator described their defense team with Cillian as "Resurrection City," noting that between the Fighter talent and the Special Skill, Cillian just refuses to leave the battlefield.
- The "Viagra" Comparison: A hilarious (if slightly crude) comment from the archives noted that Cillian "keeps resurrecting you" just like... well, you get the idea. He creates immense stamina for the team.
- Beta vs. Live: Early discussions focused heavily on the "Slow" speed being a dealbreaker, but the Family Bonus was quickly identified as the equalizer that made him playable.
Final Thoughts
Cillian is a relic from a time when "Slow" heroes were allowed to be powerful if they survived. In today's hyper-fast meta, he is often dead before he can cast his first spell. However, in the specific sandbox of Rush Attack Tournaments, the zombie samurai rises again. He is annoying, persistent, and satisfyingly dramatic when he clutches a win from the jaws of defeat.
Verdict: Keep him for Rush wars and tournaments, but don't expect him to keep up with the modern power creep in standard play.
(Note: Cillian currently has no costume, so what you see is what you get!)
