Quicken Spell-Like Ability( Monster Manual II, p. 18)
A creature with this feat can employ a spell-like ability with a moment's thought.
Spell-like ability at caster level 10th or higher,
The creature can use one of its spell-like abilities as a quickened spell-like ability three times per day (or less, if the ability is normally usable only once or twice per day). Using a quickened spell-like ability is a swift action that does not provoke attacks of opportunity. The creature can perform another action--including the use of another spelllike ability--in the same round that it uses a quickened spell-like ability. The creature can use only one quickened spell-like ability per round. The creature can only select a spell-like ability duplicating a spell with a level less than or equal to half its caster level (round down) -4. For a summary, see the table below. For example, a creature that uses its spell-like abilities as a 15th-level caster can only quicken spell-like abilities duplicating spells of 3rd level or lower. In addition, a spell-like ability that duplicates a spell with a casting time greater than 1 full round cannot be quickened.
This feat can be taken multiple times. Each time it is taken, the creature can apply it to a different one of its spell-like abilities. Quicken Spell-Like Ability. Spell -- Caster. Level -- Level. 0 ------ 8th. 1st ---- 10th. 2nd ---- 12th. 3rd ---- 14th. 4th ---- 16th. 5th ---- 18th. 6th ---- 20th. 7th ---- --. 8th ---- --. 9th -- --.
Normally the use of a spell-like ability requires a standard action and provokes attacks of opportunity unless otherwise noted.
