Rampaging Form Feat 17
Source Pathfinder Lost Omens: Ancestry Guide
Prerequisites Change Shape with a fox alternate form
Once per day, when you Change Shape into a fox, you can instead gain the effects of both the canine form of 5th-level Animal Form and 7th-level Fiery Body for 1 minute or until you shift back, whichever comes first. You can cast Produce Flame from the fiery body effect even though you're in a battle form.
Effect: Rampaging Form
Special If you are a frozen wind kitsune, your form is ice instead of fire. This changes the immunity and damage from the fiery body effect to cold, changes the weakness to fire, and changes produce flame to Ray of Frost.
