Efficient Spell (3.5e Feat)

3e Summary::You can cast a spell as a move action.

Prerequisite:

Benefit: Casting an Efficient spell is a move action which provokes an attack of opportunity. A spell whose casting time is more than 1 full round action cannot be efficient. An Efficient spell uses up a spell slot three levels higher than the spell’s actual level. You may cast only one Quickened spell or Efficient spell per round.

Special: This feat cannot 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.
