Velkhana

Description

Legends hold that this Elder Dragon can conjure great spires of ice
out of thin air and instantly freeze any creature that stands
before it, turning even massive monsters to icebound statues.

Velkhana can produce a supercooled liquid within its body that
remains below the freezing point. It expels this liquid as a breath
attack, and anything hit by it is frozen solid.

Velkhana increases the amount of supercooled water it produces
upon entering a heightened emotional state. The water eventually
overflows and coats its body before freezing.
