Bastet's Ball of Boom, version 3.5

This crystal-red orb can be hurled, launched, or otherwise transported to a location. once the user wills it, the orb explodes, dealing 10d6 fire damage to any creatures within a 15ft ball of the orb. creatures first make a dexterity save with a dc of 14 + the user's dex mod, and take half damage on a successful save. evasion rules apply. once used, the crystal shell is gone, leaving behind a metal mesh cage-ball. the crystal reforms after 23 hours, and the bomb can be used again.

"version three may have cost my brother his afro, but version three point five will burn away any who stand in our way!"
