Ahriman’s Fabulous Fireball

A bright streak flashes from you to a point you choose within range and then blossoms with a low roar into a fiery explosion. However, you may specify if and when the bright streak makes turns in its path at the time of casting. When you cast the spell, you must declare how many feet forward the streak goes, then turns, then moves forward, then turns—up to the total distance traveled equal to the range of the spell. The streak may make 2 turns on its travel, and if it makes contact with anything before then it will detonate at the point of contact. Each creature in a 20-foot-radius sphere centered on the point of detonation makes a Dexterity saving throw, taking 10d6 fire damage on a failed save or half as much on a successful one.

Higher Casting: When you cast this spell using a spell slot of 6th level or higher, the damage increases by 2d6 for each slot level above 5th. In addition, for every slot level above 5th, you may declare 1 additional turn in the fireball’s path before detonation.
