Corrosive Blade

As part of the action used to cast this spell, you must make a melee attack with a weapon against one creature within the spell’s range, otherwise the spell fails. On a hit, the target suffers the attack’s normal effects, and it becomes coated in a thin layer of bubbling acid until the start of your next turn. If the target remains in the same space until the end of its turn it takes 1d8 acid damage, and the spell ends.

A creature cannot be affected by this spell and the booming blade spell at the same time, if a creature under the affect of this spell comes under the affect of that spell, this spell ends early without dealing damage as the thunderous waves burst the acid bubble. Similarly if a creature under the affect of booming blade comes under the affect of this spell, booming blade ends early and deals no damage.

This spell’s damage increases when you reach higher levels. At 5th level, the melee attack deals an extra 1d8 acid damage to the target, and the damage the target takes for staying increases to 2d8. Both damage rolls increase by 1d8 at 11th level (2d8 and 3d8) and again at 17th level (3d8 and 4d8).
