Blood To Acid

Your touch raises the acidity in a target's blood. Make a melee Spell Attack against a creature within your reach. On a hit, the target is Poisoned for the duration of the spell.

At the end of each of the Poisoned creature's turns, it must succeed on a Constitution Saving Throw. If the target succeeds on three of these saves, it is no longer Poisoned, and the spell ends. If the target fails three of these saves, the creature's blood has become so acidic that its body starts to melt. For the remainder of the spell's duration, the creature takes 10 (4d4) Acid damage at the start of each of its turns.

If a target is killed while under the effects of this spell, its body and everything it is wearing and carrying, except magic items, are reduced to a puddle of acidic goo. A creature can be restored to life only by means of a True Resurrection or a Wish spell.
