Acid Pool

Create a 10x10 ft pool of acid, filling in holes potentially. Anytime a creature enters/exits/ends their turn in the pool, they take 3d8 Acid damage (Note: They can only be hit once per turn). While the spell is active, the caster cannot use any spells of higher level than this. This can be cancelled on a turn as an action, making the pool instantly dry up.
Slimes are immune to this spell.
