QUICKEN SPELL [METAMAGIC]
You can cast a spell with a moment’s thought.
Benefit: Casting a quickened spell is a free action. You can perform
another action, even casting another spell, in the same round
as you cast a quickened spell. You may cast only one quickened spell
per round. A spell whose casting time is more than 1 full-round
action cannot be quickened. A quickened spell uses up a spell slot
four levels higher than the spell’s actual level. Casting a quickened
spell doesn’t provoke an attack of opportunity.
Special: This feat can’t be applied to any spell cast spontaneously
(including sorcerer spells, bard spells, and cleric or druid spells cast
spontaneously), since applying a metamagic feat to a spontaneously
cast spell automatically increases the casting time to a full-round
action.
