Practiced Mind Blade

 
Prerequisite(s): Ability to form a mind blade, Concentration 4+ ranks
 
Benefit: You are treated as having 4 more levels of soulknife for the purpose of manifesting your mind blade. This benefit cannot grant you an effective soulknife level greater than your hit dice. However, even if you cannot benefit from the full bonus immediately, if you later gain levels that do not increase your mind blade, you can apply the full bonus. This feat affects only the mind blades enhancement bonus and special abilities.
