Improved Swift Banishment Feat 18ClericSource Core Rulebook pg. 127 2.0Prerequisites Swift Banishment
You easily banish creatures with your weapon. You can use Swift Banishment as long as you have a spell slot of 5th level or higher remaining, even if you don’t have
banishment prepared. You must sacrifice a prepared spell of 5th level or higher, and the
banishment effect you create is heightened to the level of that spell. Your weapon serves as the special material component of
banishment, causing the target to take the –2 penalty to its save against any
banishment you cast using Swift Banishment.
