Royal scorpion tail

The venom of this animal, which is extracted from its tail, acts by simple contact with the skin.
A creature subjected to this poison must succeed on a DC 16 Constitution saving throw or take 14 (4d6) poison damage and be poisoned for 1 minute. The creature must make a new saving throw at the end of each of its turns, ending the poisoned condition on itself on a success, or taking again 3 (1d6) poison damage in case of failure.
