Icy Weapon

Regular 
Causes any weapon to become freezing cold. This does not harm the user or the weapon, but an attack with the weapon will do +2 damage to most foes if it penetrates DR. Multiply this bonus for any Vulnerability (P, X) to ice or cold. Add this bonus to the final injury inflicted by the attack – for instance, an “impaling” icy attack is still only good for +2 damage, not +4.
