Hydaelyn

You attempt to make a creature you can see within range violently ill instantaneously. The creature must succeed on a Constitution saving throw or take 6d10 necrotic damage and become poisoned. On a success, the creature takes half as much damage and suffers no other consequences. At the start of each affected creature's turns, they take 1d10 necrotic damage and must succeed on a Constitution saving throw or spend their action retching in pain. The affected creature can reattempt the saving throw at the end of each of their turns, ending the spell effect on a successful saving throw. When you cast this spell using a spell slot of 6th level or higher, the initial damage increases by 2d10 for each slot level above 5th.
