Winter's Blast

(Complete Mage, page 48, DnD 3.5)

[Reserve]

The frozen magic within you can burst forth in a hail of frost.

Prerequisite

Ability to cast 2nd-level spells

Benefit

As long as you have a cold spell of 2nd level or higher available to cast, you can create a 15-foot cone-shaped burst of cold. This cone deals 1d4 points of cold damage per level of the highest-level cold spell you have available to cast. A successful Reflex save halves the damage. As a secondary benefit, you gain a +1 competence bonus to your caster level when casting cold spells.
