Extend Spell (Metamagic)

You can extend the duration of your spells.

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.

For a spell with a duration given as 1 round, 1 minute, or 10 minutes per level, this feat can increase the duration from one category to the next. A duration of 10 mintes/level goes to 1 hour/level. This uses up a spell slot two levels higher than the spells actual level. You can apply this version of the feat several times to the same spell.

Spell Slot Modifier	Original Duration	New Duration
+2	1 round/level	1 minute/level
+2	1 minute/level	10 minutes/level
+2	10 minutes/level	1 hour/level
