A Cryohydra is a chilling variant of the traditional hydra, possessing multiple heads that can breathe frost. These massive, reptilian creatures have the same general body structure as a typical hydra, with a crocodilian body and long, serpentine necks, but their scales are a purplish-blue hue, reflecting their icy nature.

Cryohydras are known for their ability to breathe jets of frost from each of their heads, making them even more dangerous in combat. Each head can exhale a cone of frost, dealing significant cold damage to anything caught in its path. Similar to other hydras, when a Cryohydra's head is severed, two more heads grow in its place unless the stump is treated with fire damage, as cold damage has no effect on their regenerative capabilities.
