Toxic Grasp

Poison and toxic miasma pours off your hand to deliver an enervating contact poison to a creature you try to touch. Make a melee spell attack against the target. You have advantage on the attack roll if the target is not wearing armor. On a hit, the target takes 1d8 poison damage, and it is poisoned until the end of your next turn.

The spell's damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
