Volatile Magic Missile

You create an orb of volatile glowing magical force. The orb hits a creature of your choice that you can see within range. An orb deals 3d6+1 force damage to its target in a 10 foot radius and dealing the caster 1d4 force damage backlash.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the spell increases the volatile energy contained in the orb for each slot level above 3rd. The damage increases by 1b6 force damage and the backlash damage increases by 1d4 force damage. 

Prerequisite Backlash Reduction: Class: Wizard, Spell: Magic Missile. The backlash damage can be reduced if the wizard specialized in the evocation school of magic and has the magic missile spell. The backlash damage is reduced to 1 force damage at 3rd level and increased by +1 force damage at 4th level and above.
