Cosmic Damage Type (3.5e Variant Rule)

Cosmic Damage Type
Some creatures are of such great power and force, that they can only be harmed by divine weapons and attacks. The cosmic damage type is a physical damage type similar to DR/magic and DR/epic. Weapons which bypass DR/cosmic have the requirement of being a weapon created by a deity, or having a +21 or higher enhancement bonus. Deities and certain other divine or god-like monsters should have any cases of DR/epic changed to DR/cosmic. Deities and creatures with DR/cosmic automatically bypass both DR/cosmic and DR/epic. DR/cosmic is a extraordinary ability.

For the purposes of creating magic items with DR/cosmic, it costs twice the amount as the same item with DR/epic, and the creator must have a divine rank of at least 0.
