Toxic Touch

You touch a creature and suffuse them with a toxic substance.

Make a melee spell attack. On a hit, the target takes 1d6 poison damage. The target must then make a Constitution saving throw. On a failure, the target is Poisoned. On subsequent rounds, at the end of their turn, the afflicted target must make another Constitution saving throw. On a failure, the target takes 1d4 poison damage. On a success, the target does not take poison damage, but is still subjected to the Poisoned condition. The target may make another Constitution saving throw at the end of your next turn to end this condition.

At Higher Levels. For every two levels of spell slot above 3rd, the amount of damage the target takes at the end of their turn increases by one die size. At 5th level, the poison damage becomes 1d6. At 7th level, the poison damage becomes 1d8, and at 9th level, the poison damage becomes 1d10.
