Sickening Bite
FEAT 8Your saliva causes severe nausea and mild fever in the living, weakening them so that you can more easily finish them off. When you critically hit a creature with your jaws, the creature is Sickened 1. This is a disease effect.
If you are satiated, you can end your satiation to make the target Sickened 1 on a regular hit instead.
