Mass Spell

Mass Spell (Metamagic)
You can increase the number of targets your spell effects.
Benefit: You may apply this metamagic feat to any spell that targets as single creature. The spells parameters change to the following:

• Range close (10 ft./level)
• Target one creature/level, no two of which can be more than 30 ft. apart

A mass spell uses up a spell slot four levels higher than the spell’s actual level. Any restrictions on the type of creature targeted do not change.
