Quicken Spell (Feat)

You can cast spells in a fraction of the normal time.

Prerequisites: Caster Level 9

Benefit: Casting a quickened spell is a swift action. You can perform another action, even casting another spell, in the same round as you cast a quickened spell. A spell whose casting time is more than 1 round or 1 full-round action cannot be quickened.

Casting a quickened spell doesn't provoke an attack of opportunity.

You can apply the effects of this feat to a spell cast spontaneously, so long as it has a casting time that is not more than 1 full-round action, without increasing the spell's casting time.

Level Increase: +4 (a quickened spell uses up a spell slot four levels higher than the spell's actual level.)
