Extend Spell

Extend Spell (Metamagic)
You can make your spells last twice as long.
Benefit: An extended spell lasts twice as long as normal. A spell with a duration of concentration, instantaneous, or permanent is not affected by this feat. An extended spell uses up a spell slot one level higher than the spell’s actual level.

(CL 5th): You may prepare or use Extend Spell once per day without using a higher spell slot.
