The creature can employ a spell-like ability with a moment’s thought.
Prerequisite: Spell-like ability at caster level 10th or higher.
Benefit: Choose one of the creature’s spell-like abilities, subject to the restrictions described below. The creature can use that ability 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 an attack of opportunity. The creature can perform another action—including the use of another spell-like ability—in the same round that it uses a quickened spell-like ability. The creature may 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 Quicken Spell-Like Ability 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.
| Spell Level | Caster Level to Quicken |
|---|---|
| 0 | 8th |
| 1st | 10th |
| 2nd | 12th |
| 3rd | 14th |
| 4th | 16th |
| 5th | 18th |
| 6th | 20th |
| 7th | — |
| 8th | — |
| 9th | — |
Normal: Normally the use of a spell-like ability requires a standard action and provokes an attack of opportunity unless noted otherwise.
Special: 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.
