Ancient Rime Dragon

An ancient rime dragon carries winter in its bones, and the air around it crackles into frost the moment it draws near. Cold pours off its scales in a constant, killing tide that saps the warmth and speed from anything foolish enough to close the distance.

Radiate Cold (aura, cold, primal) 15 feet. The adult rime dragon's presence lowers the temperature around them. A creature who enters or begins their turn in the aura must attempt a DC 33 Fortitude save.

• Critical Success The creature is unaffected.
• Success The creature begins to shiver as the biting cold affects it. It takes a –5-foot status penalty to its Speeds until the end of its next turn.
• Failure The creature's body temperature begins to drop. It takes a –10-foot status penalty to their Speeds and is enfeebled 1 until the end of its next turn.
• Critical Failure Ice begins to form on the creature.
