Strong Jaw. You can bite as a natural weapon that deals damage equal to your Strength plus d6 with Armor Piercing 2.
Poisonous Bite. You can bite as a natural weapon that deals damage equal to your Strength plus d4. The target must make a Vigor roll or suffer the effects of mild Poison. You may administer a concentrated dose of your venom, forcing the target to suffer a -2 penalty to his Vigor roll, but doing so causes you Fatigue.
Poison Spit. With a successful Athletics roll as a limited action, you spit poison at a target up to 6“ (12 yards away). The target must make a Vigor roll or suffer the effects of Disabling Poison. You may concentrate this poison to give the target a -2 to their Vigor roll at the cost of you taking Fatigue.
