Bakudan Orb

2nd-level evocation

Casting Time: 1 action

Range: 60 feet

You conjure an orb of condensed energy and hurl it at a point within range. The orb sticks to the surface or creature it hits. At the start of your next turn, it detonates. Creatures within 10 feet of the explosion must make a Dexterity saving throw, taking 4d6 force damage on a failed save or half as much on a successful one.
At Higher Levels: When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot level above 2nd.
