In short
  • The Chimera is the newest of the three clan bosses. It opens at account level 33, you fight it with five champions, and the battle is capped at 65 turns.
  • You get two keys a week. Your damage earns a chest, and if the clan defeats the boss, everyone's rewards double.
  • It changes form as the fight goes on - Ultimate, Ram, Lion and Viper - and each form punishes a different kind of team.
  • Its rewards are the materials that make and upgrade relics: Starstone, Basalt and gemstones.
  • Besides the main fight, there are separate "trials" for each form with goals to meet.

What it is

The Chimera is a clan boss, like the Clan Boss (Demon Lord) and the Hydra, so you need a clan. Where the Clan Boss has no turn limit and the Hydra gives you six champions, the Chimera is short and strict: five champions, 65 turns, and your score is the damage you dealt in that time.

TeamFive champions
Length65 turns
KeysTwo per week, handed out after the weekly reset
DifficultiesEasy, Normal, Hard, Brutal, Nightmare and Ultra-Nightmare; each stays open for the clan once reached
Note The number of keys and of difficulties are what the guides we read agree on in September 2026, but a hosted older guide lists fewer difficulties. Count them on the Chimera screen. Checked October 2026.

The four forms

The Chimera cycles through four forms during a fight. The Ultimate form is its strongest state, and it appears between the animal forms. Ram, Lion and Viper are the other three, each with its own set of attacks and rules. Reports describe the forms changing every few turns in a fixed order, and repeating that order twice within the 65 turns. Its affinity rotates about every four weeks.

The practical consequence is that you cannot play the whole fight the same way. A team that is great against one form can be in trouble in the next, and your champions' cooldowns need to be ready when the form that you can hurt most arrives.

Tip Open the boss's skills for each form once, before your first run. Most failed first runs come from one form's special rule that the team did not know about.

What a team needs

The Chimera is damaged by the usual set of weakening effects, and its fight is short enough that burst and survival both count. Teams commonly want:

NeedLook for
Weaker enemyDecrease DEF, Weaken, Decrease RES
Slowing it downDecrease SPD
SustainHeal, Continuous Heal, Leech
Using its attacks against itReflect Damage, Counterattack, Pain Link
Staying cleanBlock Debuffs

Crowd control is less central than for the dungeon bosses, and we have no confirmed list of what the Chimera is immune to, so read its description in the game before you plan around a control skill. The buffs and debuffs guide explains each effect.

Trials

Trials are the second part of the mode. Each form has its own trials, and they come in difficulty levels that unlock in order. A trial is a Chimera battle with a goal attached; the goal is written on the trial's screen. Rewards are paid right after the battle and cost a Chimera key.

Careful Using the free regroup button in the middle of a trial cancels your score and the trial's reward. Check the button before you press it.

Trials are also reported as a source of Chimera relics and of the Mythical champion Embrys the Anomaly. That is one source's claim and has not been confirmed.

Chests and rewards

Your chest depends on your own damage on the difficulty you fought. The chest ladder has eight steps, from Novice at the bottom to Ultimate at the top, and the damage needed rises with each difficulty. Chests give a random selection from this list:

  • Clan Gold and Clan XP.
  • Starstone and Basalt, the materials that level up and rank up relics.
  • Ocular Masses and Circular Gemstones, in several rarities.
  • Champion fragments, though not every chest holds them.

The better chests hold more items. Defeating the Chimera doubles the total the clan earns.

Note The damage you need for each chest changes with each difficulty and has been rebalanced before, so no numbers are listed. Checked October 2026.

How to approach it

  1. Learn the forms. Read the skills of Ultimate, Ram, Lion and Viper, and note the one that scares you.
  2. Start on a difficulty your team survives.
  3. Build for the whole 65 turns. A team that dies on turn 40 leaves a lot of damage unused.
  4. Spend both keys every week. Check the key timer in the game so none is wasted.
