Multiple Heads. The hydra has ten heads. While it has more than one head, the hydra has advantage on saving throws against being blinded, charmed, deafened, frightened, stunned, and knocked unconscious.

Whenever the hydra takes 30 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 radiant damage since its last turn. The hydra regains 10 points for each head regrown in this way.

Reactive Heads. For each head the hydra head has beyond one, it gets an extra reaction that can be used only for opportunity attacks.
