Poison Skin
Level 3 · Abjuration · Ritual · Concentration
The target becomes poisonous to the touch. Until the spell ends, whenever a creature within 5 feet of the target damages the target with a melee weapon attack, the creature makes a Constitution saving throw. On a failed save, the creature becomes poisoned and takes 1d6 ongoing poison damage.
A poisoned creature can make a Constitution saving throw at the end of each of its turns, ending the effect on itself on a success.
The target of the spell also becomes bright and multicolored like a poisonous dart frog, giving it disadvantage on Dexterity (Stealth) checks.
