From D&D Wiki
 Another Slice of Shade [General]
You summon the night within to guide your blade.
Prerequisite: Shadowblade 5th, ability to use darkness as a spell-like or supernatural ability
Benefit: You may convert one of your daily uses of your darkness ability to use an additional unseen weapon power per round. You may use unseen weapon as a swift action (or free action at higher levels) as normal and you may use it an additional time that round as a free action (or as a swift action if you have used your free action for that round).
Special: You gain one additional use of unseen weapon per day. If you can use darkness more than once per day, you must wait 1d6 rounds before using it or this feat.
