Description

A hydra is an especially deadly monster, since every time a head is severed, two new ones grow in its place.

A hydra is not very intelligent, and therefore usually neutral in alignment. They usually live alone in swamps, and are generally always the most dangerous predator in the area they inhabit.

In the "Eberron" campaign setting, the hydra is the heraldic beast of the dragonmarked House Phiarlan.

Variants

The pyrohydra is a relative of the standard hydra that is able to breathe fire from its heads.

The cryohydra is another relative of the standard hydra, this one being able to breathe jets of frost.
