Feat: Blazing Mutagen

You can adulterate alchemical mutagens with volatile goblin oils that spill from your pores, coating your weapons and skin. While under the effects of the mutagen, your melee Strikes deal 1d4 additional persistent fire damage. When you drink the mutagen, you take 2d4 persistent fire damage, which ignores resistances and immunities to fire. If your persistent fire damage ends, you no longer deal persistent fire damage with your Strikes.
