Align Mind Blade

 
Prerequisite(s): Ability to form a Mind Blade, BAB 6+
 
Benefit: Choose an alignment: Good, Evil, Lawful, Chaotic. Your mind blade gains this alignment, allowing it to overcome the damage reduction for that alignment. The chosen alignment cannot be opposite your own, however a neutral character can choose any alignment. You may take this feat twice. You must choose a different alignment each time, you cannot choose an alignment opposite to the one you have already chosen.
