Continual Spell (Metamagic)

You can make one of your spells last all day.

Prerequisite: Extend Spell, Stack Metamagic.

Benefit: A continual spell lasts 24 hours or until dispelled. Only spells that may be made permanent with a permanency spell may be cast as continual spells. A continual spell uses up a spell slot four levels higher than the spell’s actual level.
