💀 Clan Bosses
Demon Lord, Hydra, and Chimera — stages, required stats, must-have compositions, and Chimera Trials including Fahrakin-based setups.
💀 Contents
There are three distinct Clan Bosses. Each has different keys, mechanics, and reward pools. This guide covers all three.
Demon Lord (Classic Clan Boss)
Keys & Basics
- 5 keys per player per day, shared across all difficulties
- You choose which difficulty to fight — higher difficulty = more chests, more rewards
- All team affinities fight the same boss
- The boss hits all 5 of your champions simultaneously with every attack
Stat Requirements by Difficulty
| Difficulty | Min SPD | Min ACC | Min DEF |
|---|---|---|---|
| Easy | 130 | 70 | 1,800 |
| Normal | 140 | 100 | 2,100 |
| Hard | 150 | 150 | 2,400 |
| Brutal | 160 | 170 | 2,700 |
| Nightmare | 170 | 200 | 3,000 |
| Ultra-Nightmare | 190 | 230 | 3,500 |
DEF is worth more than HP against the Clan Boss
The boss cannot reduce your champions’ DEF. HP is mitigated by DEF. Prioritise DEF over raw HP — 99% of the time DEF is the better investment for survivability.
Must-Have Debuffs (Priority Order)
| Debuff | Effect | Priority |
|---|---|---|
| Decrease Attack | –25% incoming damage | Mandatory — team dies without it |
| Poison (×10 max) | Primary damage source | Mandatory — stack as many as possible |
| Weaken | +25% damage CB takes | Very high — multiplies everything |
| HP Burn | High fixed damage (1 active) | High — but only one slot, don’t stack |
| Decrease Defence | More damage at higher difficulties | High for NM/UN |
| Leech | Heals from CB hits | Useful if not running Lifesteal |
Accuracy gates everything
If your ACC doesn’t meet the threshold, debuffs simply won’t land. Decrease Attack failing means your team dies early. Hit the ACC floor before worrying about any other stat.
Must-Have Buffs
| Buff | Why |
|---|---|
| Counter Attack | Extra hits every time the boss attacks — doubles or triples your damage output |
| Increase Defence | Massive survivability multiplier |
| Continuous Heal | Sustain alongside Lifesteal |
| Ally Protection / Shield | Damage sharing — keeps squishier champions alive |
| Unkillable | Advanced endgame — team cannot die, maximises key value |
Core Compositions
Standard (mid-game) — Lifesteal + Poisons:
Speed lead → Decrease ATK (100% uptime) → 2× Poisoners → Support/Healer
Gear everyone in Lifesteal. This is your baseline until you can speed-tune.
Unkillable (endgame) — Maneater + Pain Keeper:
The classic unkillable duo provides permanent invulnerability windows. Requires precise speed tuning (Maneater and Pain Keeper must act in a specific order every cycle). Dramatically increases key value — team effectively never dies.
Counter Attack (mid-endgame) — Skullcrusher or Valkyrie:
Counter Attack champion enables the whole team to hit on every boss attack. Pairs well with poisoners to stack debuffs faster. Easier to build than unkillable and nearly as effective.
Speed Tuning
Advanced teams run at the same speed as the boss so that every champion acts before each boss attack. This requires knowing your difficulty’s boss speed and tuning accordingly. The DeadwoodJedi speed calculator is the standard tool for this — the exact tuning matters more at NM/UN than at Brutal.
Hydra Clan Boss
Keys & Basics
- 3 keys per week, resets every Thursday
- 6 champions per key — 18 unique champions needed across all 3 keys (each champion can only be used once per week)
- Duplicates are allowed within a single key but not across keys
- 4 heads active at once; when one is defeated another rises from the bench (2 waiting)
- Head composition rotates monthly — same 4 heads for an entire month before changing
- Clan must defeat a difficulty tier to permanently unlock the next one
Head Types & Counters
| Head | What it does | How to counter |
|---|---|---|
| Head of Blight | Poison attacks + Poison Cloud buff on all heads | HP Burn removes Poison Cloud from all heads simultaneously |
| Head of Torment | Fear debuffs that bypass normal Resistance | Champions with Perfect Veil; debuff removal / cleanse |
| Head of Mischief | Steals your buffs; redirects single-target attacks away | Hex debuffs; use AoE attacks instead of single-target |
| Head of Wrath | Builds Vengeance counter → quadruples damage | Stack Increase DEF, Strengthen, and Shields |
| Head of Decay | Destroys 15% of each heal received | Decapitate this head early; minimise reliance on big heals |
| Head of Suffering | Pain Link: 15% of damage you deal redirects back to your team | High Resistance; debuff removal |
Mark of the Hydra — 16-turn countdown
One champion gets marked each fight. After 16 turns, they’re devoured and placed in Digestion — requiring 150k–400k damage (scales by difficulty) from allies to rescue them. Plan revivals and AoE damage to pull devoured champions back quickly.
Decapitation Strategy
Killing a head removes it for 2 turns and grants a 200% damage bonus window. However, it also removes all debuffs from all remaining heads — resetting your Poison stacks, HP Burn, Weaken, everything.
- Kill heads one at a time during high-damage windows
- Reapply debuffs immediately after decapitation
- Head of Decay should be prioritised for early decapitation (eliminates the heal penalty for the rest of the fight)
Must-Have Composition Elements
- HP Burn — mandatory when Head of Blight is active (removes Poison Cloud)
- Hex — mandatory when Head of Mischief is active
- Revive / Resurrect — champions get devoured; someone needs to pull them back
- AoE debuff application — multi-head encounters mean single-target debuffers fall short
- Decrease ATK — same as Classic CB, mandatory for survival
- Weaken — applies to all heads, huge damage multiplier
Key Rule: 18 Unique Champions
Build three teams of 6 with no overlaps. This forces you to use your bench. Design your teams by:
- Team 1 — your strongest setup with highest Hydra-specific synergy
- Team 2 — second-tier champions covering the same key debuffs
- Team 3 — whatever remains; focus on at least keeping Decrease ATK covered
Unique drops: Righteous, Tate, and Chill gear sets drop here and nowhere else.
Chimera Clan Boss
Basics
- Requires Account Level 33 and clan membership
- 5 champions per fight
- The fight is exactly 65 turns — it doesn’t end when you kill the boss (you can’t). Damage dealt in 65 turns determines chest tier.
- Weekly keys (quantity depends on your clan’s Chimera progression)
- Unique reward: Embrys the Anomaly champion fragments from high-damage chests
The Four Forms
The Chimera cycles through all four forms in a predictable rotation. Forms are not random.
| Form | Core Mechanic | Key Counter |
|---|---|---|
| Ultimate | AoE + Provoke; strips buffs (Consume Matter); uses your debuffs against you (Pincer Lash). At 25+ Trials: gains +15% ATK, +15% CritDmg, 100% ignore DEF | Block Debuffs is critical here |
| Ram (Duel) | Locks your lowest CritDmg champion into 1v1. Target takes 50% more damage. Strips buffs during Duel. You must deal damage equal to 1% of Ram’s max HP per turn or the damage escalates | Max HP-scaling skills, high CritDmg across team |
| Lion (Hunter’s Gaze) | Marks your highest-DEF champion — all damage they receive is unavoidable, ignores Shields and Strengthen. | Raw HP and healing; don’t over-stack DEF on one champion |
| Viper (Necrosis) | Each time a champion dies, surviving allies gain Necrosis stacks (5% max HP damage per stack per turn). Stacks are removed when the dead champion is revived. | Revive champions immediately — don’t let Necrosis snowball |
Stat Requirements (Nightmare example)
Accuracy requirements vary by form within the same fight:
| Form | Resistance | ACC needed |
|---|---|---|
| Ultimate | ~325 | 350+ |
| Ram | ~425 | 450+ |
| Lion | ~350 | 375+ |
| Viper | ~375 | 400+ |
Ram Form has the highest Resistance — 450+ ACC needed
Most players gear for Nightmare overall and find their debuffs land in most forms but miss in Ram. Build to 450+ if you want full trial completion on Ram.
The Trials System
Each of the three active forms (Ram, Lion, Viper) has 9 trials (3 tiers × 3 objectives), for 27 total.
Completing trials earns Clash Points and bonus rewards. More importantly: completing 25–27 trials empowers the Ultimate Form (it gains 15% ATK, 15% CritDmg, and 100% ignore DEF). Avoid this if your team can’t handle an empowered Ultimate.
Trials require specific skill types to be active during the fight:
| What trials need | Examples |
|---|---|
| Poison debuffs | Champions who place 5% or 2.5% Poison |
| HP Burn debuff | Any champion with HP Burn on kit |
| Ally Attacks | Fahrakin, Lady Mikage, Rotos, Taras |
| Counter Attacks | Skullcrusher, Valkyrie, Martyr |
| Max HP-scaling damage | Gnut, Marius the Gallant, Titus |
| Revivals | Rector Drath, Pythion, Bad-el-Kazar |
| Decrease Defence | Standard debuff, many champions |
| Reflect Damage | Specific skill type — rarer |
Fahrakin the Fat — Trial Enabler
Fahrakin is one of the single best Chimera trial enablers because his kit alone covers multiple trial requirements:
- A2 (Brand of Shame): Places HP Burn + 2× Poison in a single skill use → satisfies HP Burn trials AND Poison trials simultaneously
- A3 (Warband): Full-team Ally Attack with Increase Crit Rate + Increase Crit Damage → satisfies Ally Attack trials (Lion Form Trial #2 line is trivially completed with an Ally Attack champion)
- A1: Decrease Defence → satisfies Decrease DEF trials
A team built around Fahrakin can reach 18+ trials per fight. Pair him with a second Ally Attack champion (Lady Mikage, Rotos) and a reviver for maximum trial completion.
Other Top Chimera Champions
| Champion | Why |
|---|---|
| Titus Blackplume | Top damage dealer — shield-scaling damage compounds massively over 65 turns |
| Gnut / Marius the Gallant | Max HP-scaling damage satisfies Ram form trials and does consistent baseline damage |
| Pythion (Lizardmen) | Comprehensive support: Dec ATK, cleanse, heal, revive — addresses nearly every team gap |
| Rakka | Underrated — strong multi-trial enabler with a unique skillset |
| Rector Drath | Revive + healing — essential for Viper Form necrosis control |
Chest Rewards
Higher damage = better chest tier. On Ultra-Nightmare:
- Ultimate Chest requires 112.5M+ damage
- Rewards: up to 8 items including Mythical Gemstones and Embrys the Anomaly fragments
- Chimera is the only source of Mythical relic crafting materials — your Chimera performance directly gates how fast you access Mythical relics
Trials vs damage — know your priority
Completing 25+ trials empowers the Ultimate Form, which can hurt teams that aren’t built to handle it. If your team can’t sustain through an empowered Ultimate, cap at 24 trials deliberately. Once your team is strong enough, full trials = more Clash Points + better chest qualification.
