Major Mutation - Poison Dart Frog Skin

The glands in your skin start to transform and excrete a poisonous substance. You gain the following trait:

Poisonous Skin. Any creature that grapples you or otherwise comes into direct contact with your skin must succeed on a DC 12 Constitution saving throw or take 1d4 poison damage and become poisoned for 1 minute. A poisoned creature no longer in direct contact with you can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
