Mark of Purity

(Dragonmarked, page 142, DnD 3.5)

[General]

Your dragonmark renders you immune to effects that would sicken or nauseate you, and gives you the power to rid others of similar debilitations.

Prerequisite

Divine health or purity of body, any true dragonmark.

Benefit

You cannot be sickened or nauseated. In addition, by touching a sickened or nauseated creature as a standard action, you instantly remove that condition.
