I'm working on a Darth Vader build for a competition. To represent the light saber, I would really like to use mind blade (from the 3.0 Soulknife prestige class, which is actually pretty cool, especially compared to the 3.5 base class). However, the Monk ACF Decisive Strike would make a fantastic addition to the build, and this ACF replaces Flurry of Blows.
Problem is, Unorthodox Flurry and Whirling Steel Strike - either of which would make the mind blade a special monk weapon - both have "flurry of blows class feature" as a prerequisite, so I can't use them. My second thought was Shou Disciple, but it only lets you flurry with other weapons; it doesn't make them special monk weapons, and thus it wouldn't let you decisive strike with mind blade either. The Eberron Monk substitution levels give you Whirling Steel Strike as a bonus feat, which would normally obviate the need for the prerequisites... but explicitly still requires all prerequisites. There are also numerous classes that give you a "flurry" of some flavor, but none I've found so far are specifically a "flurry of blows" that would work as a monk-independent way of qualifying for one of the feats.
So how about it? Is there a way to make a mind blade, short sword, or longsword* count as a monk special weapon that doesn't also require you to have Flurry of Blows?
Or a way to count as having the "Flurry of Blows class feature" to qualify for a feat?
Or for that matter, a way to get Decisive Strike without trading away Flurry of Blows?
*The Soulknife prestige class (Psionics Handbook pg 113) says the mind blade is "identical to" a short sword until level 8, at which point it's "identical to" a longsword. As far as I'm concerned, that means any method that works for one of those also works for the mind blade. It also means longsword is the least preferable of the three.
