Wrecking Ball

Cult of Rakdos Spell
Level 4
Casting Time: Action
Duration: Instantaneous
Range: 80 ft
You send a small mote of fire towards an object in range, when it reaches their space, it blossoms into a massive 20 ft radius sphere fireball. Each creature within range must make a Dexterity Saving Throw, taking 7d10 on a fail and half as much on a success. Damage dealt by this spell to structures is twice as much.
