Clan Boss · weekly
Hydra
Hydra is Raid’s second clan boss: it resets weekly, gives three keys, and each champion can be used once per week — so using every key takes 18 champions. You fight four of six heads at a time; chopping a head exposes a neck that takes double damage.
How Hydra works
- ◆
Hydra is the second Clan Boss (launched in Patch 5.0); it resets weekly and each player gets 3 Hydra keys per week.

Teams bring 6 champions, and each champion can be used only once per week — 18 champions are needed to use all three keys.

There are six Hydra Heads (Torment, Decay, Suffering, Mischief, Blight, Wrath); you fight 4 at a time while 2 wait as substitutes.

Starting heads and their affinities rotate monthly.

Decapitating a head disables it and exposes the neck, which takes 200% damage; when it regrows it gains a buff that cuts incoming damage by 75%.

Consumption mechanic: the champion with the highest Critical Damage gets a 20-turn countdown and is then swallowed; dealing enough damage (150k Normal to 400k Nightmare) frees it, otherwise it is digested.

Hydra difficulties are Normal, Hard, Brutal and Nightmare; e.g. Nightmare chests run from Knight (~9.15M) up to Grandmaster (over ~36.6M).

Heads are immune to Stun, Freeze, Sleep, Provoke, Block Active/Passive Skills, Fear, True Fear and Petrification; MAX-HP-based damage, HP Burn ticks and Warmaster/Giant Slayer procs are capped.
