Burst of Glacial Wrath

Notes:
 * Using metamagic feats increases the cost.
 * Freeze effect causes helplessness and frozen monsters take +50% damage.
 * Freeze effect does not affect Orange named monsters
 * Freeze is coded as a mind altering effect. It will not affect mindless monsters such as undead or oozes, but will affect cold-based monsters like winter wolves and ice mephits.
 * Freeze helplessness appears to take effect after the cold damage, ie it's not multiplied.
