Redcap's Corner Pathfinder
Prerequisite: two techniques
Once per day, as a full-round action, you create an area of rainfall in a 20-foot-radius burst, centered within 40 feet of you. This rainfall lasts for one minute + one additional round for every technique you know. As long as a creature remains within the area of this burst, it has fast healing (Bestiary, pg. 300) equal to the number of techniques you know.
