Combat:
Breath Weapon (Su):
As the breath weapon of a white wyrmling, except as noted:
It can be made as a move-equivalent action, and does not need to "recharge". Rather than a cone, the breathe weapon covers a 20-foot radius sphere, centered on the center of the swarm (i.e., it extends 15 feet past the edge of the swarm's space in all directions). Additionally, the DC is adjusted to match its hit-dice.
Icewalking (Ex)
This ability works like the spider climb spell, but the surfaces the dragon climbs must be icy. It is always in effect.

PEACH!
