You can cast a spell very quickly at the cost of greatly reduced duration.
Prerequisite: Dex 13.
Benefit: A swift spell is cast as a swift action. You may only use Swift Spell on a spell with a range of touch or you, and only on spells that normally have a duration of at least one minute (ten rounds) when you cast them. The duration of a swift spell is reduced to one round. A swift spell uses up a spell slot zero levels higher than the spell’s actual level (that is, exactly the same level as the original spell).
