You surrender your body to the cold, slowing your movement but channeling a surge of frost power into your spells. While active, all cryo spells you cast deal additional cold damage. Even non-damaging area spells with freezing effects gain a biting edge, inflicting minor damage to those caught within.
All frost spells cast for the duration deal extra damage. Also adds damage to area spells that does not deal damage, but only freeze those in the area.
