Delayed blast fireball

Delayed blast fireball, or delayed blast fire ball was an evocation spell that was like fireball but could be given a timed detonation.

Effect
Other than being similar to fireball, the damage of the spell was increased and the spell would detonate with a timed trigger. Later versions of the spell created a fiery "bead" that could be thrown and explode, sometimes in the thrower's hand.

The post-Sundering version of the spell could be made even more powerful if cast with a higher level.

Components
Only verbal and somatic components were needed for the casting.
