You add ice or snow to your spell's components to make them more powerful.
Prerequisite: Con 13.
Benefit: If you add a handful of snow or ice as an additional material component to a spell when you cast it, the spell gains the cold descriptor. This does not actually change the nature of the spell you cast; a fireball cast with this feat still deals fire damage, but since it also carries the cold descriptor, it can be augmented by a number of feats listed in this chapter, such as Cold Focus and Frozen Magic.
If you add a handful of snow or ice as an additional material component to a spell when you cast it and that spell already has the cold descriptor, you increase the effective level of the spell being cast by +1.
Adding this additional material component requires you to spend a move action immediately before the spell is cast to gather fresh snow or ice from the surrounding environment. This snow or ice can be magically created by a conjuration spell, but no other ice manifested by a spell will do. You may take no other action between gathering the snow or ice and casting the spell.
