Dracir's bouncing Fireball

At a young spellcaster, Dracir was always jealous of higher level spells potentional.  So she decieded to update and make minor adjustments to existing spells.

Dracir's Bouncing fireball fires a single ball of fire towards a target in range for 1d4 + caster level points of damage, then bounces off target to floor to detonate for 1 +caster level points of damage in a 10' radius.

At later levels damage and targets increase.  Example, 5th level caster equals 5d4+5 first target, 4d4+5 second, 3d4+5 third, 2d4+5 fourth, 1d4+5 fifth, then goes to ground dealing 6 points explosive damage.  Ball can hit allies.
