Blood to Acid 2014

When you cast this spell, you designate a creature within range and convert its blood into virulent acid. The target must make a Constitution saving throw. On a failed save, it takes 10d12 acid damage and is stunned by the pain for 1d4 rounds. On a successful save, it takes half the damage and isn’t stunned.

Creatures without blood, such as constructs and plants, are not affected by this spell. If blood to acid is cast on a creature composed mainly of blood, such as a blood elemental or a blood zombie, the creature is slain by the spell if its saving throw fails.
