You may be small, but the poison glands concealed across your body hide a deadly defense. You gain the Toxic Skin reaction.

Toxic Skin (poison) Frequency once per hour; Trigger A creature touches you, such as by Grappling you, successfully hitting you with an unarmed attack, or using a touch-range spell against you; Effect You exude a deadly toxin. The triggering creature takes 1d4 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.
