Pathfinder 2e Action / Feat: Feral Mutagen

Description Your bestial mutagen brings out the beast lurking within you, granting you especially sharp claws and teeth as well as a ferocious appearance. 
Applications Whenever you’re affected by a bestial mutagen you created, you gain the mutagen’s item bonus to your Intimidation checks. In addition, your claws and jaws are increasingly vicious, and they gain the deadly d10 trait. Finally, you can increase the mutagen’s penalty to AC from –1 to –2 and, in exchange, increase the damage die size of your claws and jaws by one step.
