Flash Frost Spell

 
Prerequisite(s): None
 
Benefit: This metamagic feat can be applied only spells with the cold descriptor and that affect an area. A flash frost spell deals an extra 2 points of cold damage for every level of the spell cast. When you cast such a spell, the area of the spell is covered in a slippery layer of ice for 1 round. Anyone attempting to move in this icy area must make a DC10 balance check or fall prone. A creature that runs or charges through the area must make a DC20 balanace check to avoid falling. The Flash Frost spell uses a spell slot two levels higher than normal.
