Toxic Skin
REACTION reaction
once per hour
A creature touches you, such as by Grappling you, successfully hitting you with an unarmed attack, or using a touch-range spell against you
You exude a deadly toxin. The triggering creature takes 1d4 per 2 levels (rounded up) poison damage (basic Fortitude save using your class DC or spell DC, whichever is higher). At 3rd level and every 2 levels thereafter, the damage increases by 1d4.
