Mass Effect Spell

 
Prerequisite(s): None
 
Benefit: A spell that normally affects a single target now affects one target per level, no two of which can be more than 30 ft. apart. A mass effect spell uses up a spell slot four levels higher than the spell’s actual level. Range is not changed in any way, except that touch spells can be cast on a chain of creatures all touching one another. This feat does not work on spells with a “personal” range.
