As title suggests I'm here to ask if the feat allows you to cast DDoor as a swift action. It gives abundant step as an alternative but that ability also can only be activated as a move normally. So slightly confused basically need to know if I need to get quicken spell or look for annother way to cast as a swift action.
You can take a full-attack action, activating abundant step or casting dimension door as a swift action. If your do, you can teleport up to twice your speed (up to the maximum distance allowed by the spell or ability), dividing this teleportation into increments you use before your first attack, between each attack, and after your last attack. You must teleport at least 5 feet each time you teleport.
Under specific conditions this feat allows you to cast D Door as a swift action; this includes Abundant Step. So you do not need to have a separate ability to use D Door as a swift action.
The specific condition is making a full attack action. So you cannot use Dimensional Dervish to cast a Fireball and then D Door away.
