Corrosive Cuddle

Make a melee spell attack against a creature. On a hit, the creature takes 2d10 acid damage and is grappled. The attack has advantage if the creature was already grappled.

If the creature is grappled, it takes 1d10 acid damage at the start of each of its turns. The spell ends early once the creature is no longer grappled.

When cast with a higher level spell slot: The initial damage increases by 1d10 for each spell level above 1st.
