Fox Arson Feat 9Fire Kitsune Source Tian Xia Character Guide pg. 50
When you critically hit with a
foxfire Strike, the target takes an additional 1d4
persistent damage of the same type as the foxfire. You gain an item bonus to this persistent damage equal to the foxfire’s item bonus to attack rolls. When the target taking persistent damage comes into physical contact with another creature (for instance, if one of its allies touches it while
Administering First Aid), you can use a reaction to command the flame to leap to the second target, ending the persistent damage on the first creature and moving it to the second.
Traits
Fire: Effects with the fire trait deal fire damage or either conjure or manipulate fire. Those that manipulate fire have no effect in an area without fire. Creatures with this trait consist primarily of fire or have a connection to magical fire.
Planes with this trait are composed of flames that continually burn with no fuel source. Fire planes are extremely hostile to non-fire creatures. Unprotected wood, paper, cloth, and other flammable materials catch fire almost immediately, and creatures wearing unprotected flammable clothing catch fire, typically taking 1d6 persistent fire damage. Extraplanar creatures take moderate environmental fire damage at the end of each round (sometimes minor environmental damage in safer areas, or major or massive damage in even more fiery areas). Ice creatures are extremely uncomfortable on a fire plane, assuming they don’t outright melt in the heat.
Kitsune: Shapeshifting humanoids whose true forms resemble foxes.
