Hydra

Hydrae are immense reptilian monsters with multiple heads. Hydrae are gray-brown to dark brown, with light yellow or tan underbellies. Their eyes are amber and their teeth are yellow-white. Hydrae have between 5 and 12 heads.

There are several distinct types of hydrae in addition to the one mentioned above:

• Lernaean hydrae will regenerate two heads for each one that is severed. A maximum of 12 heads can be grown. New heads form in minutes and can be avoided only by the prompt application of flame to the neck following the attack which destroyed the first head. This hydra's body is immune to all attacks.

• Pyrohydrae are reddish hydrae have 7 or 8 heads which are able to breathe a jet of fire twice per day.

• Cryohydrae are purplish-brown hydrae able to breathe a stream of frost.

Note: Hydrae originally appeared in this form in the 2nd Edition Monstrous Manual for the AD&D game from TSR. Their use here is for the purposes of providing context for the campaign only.
