Conjure Boiling Cauldron

You summon a floating cauldron full of boiling oil above a point within range. When you first cast the spell creatures in a 10ft square directly below the cauldron must make a Dex saving throw; suffering 3d6 fire damage on a failure or half as much on a success. On subsequent turns you can use a bonus action to dump the cauldron again on creatures below in the same 10ft square.

                At Higher Levels. When you cast this spell using a spell slot of 3 or higher, the damage increases by 1d6 for each level beyond 2
