Venom Maw Hydra 2014
CR 12 monstrosity
Huge monstrosity, unaligned
The venom maw hydra can breathe air and water.
The venom maw hydra has five heads. While it has more than one head, the venom maw hydra has advantage on saving throws against being blinded, charmed, deafened, frightened, stunned, and knocked unconscious. Whenever the hydra takes 25 or more damage in a single turn, one of its heads dies. If all its heads die, the hydra dies. At the end of its turn, it grows two heads for each of its heads that died since its last turn, unless it has taken cold damage since its last turn. The hydra regains 10 hp for each head regrown in this way.
While the hydra sleeps, at least one of its heads is awake.
