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-Second Sundering version of the spell could be made even more powerful if cast by a user with more skill.

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

History
This spell was invented by the arcanist and Fire Warden of Netheril Noanar and called Noanar's delayed fireball in (two years earlier than the simpler fireball).
