Big Bang Attack

You form a condensed, unstable sphere of explosive ki in your palm and hurl it at a point you can see within range. The sphere detonates on impact.

All creatures within a 20-foot radius sphere centered on that point must make a Dexterity saving throw. A creature takes 6d8 fire or force damage (your choice when casting) on a failed save, or half as much on a successful one.

Unattended objects flammable materials ignite on impact.

At Higher Levels: When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d8 for each slot level above 3rd.
