One mind, a blur of motion, and a thousand strikes. This is the way of the xeph soulknife.
Prerequisites: Xeph, ability to generate a mind blade
Benefit: When you make a full attack with your mind blade, you may make an additional attack at your highest base attack bonus, but all your attack rolls suffer a -2 penalty until the start of your next turn.
If you have the Spring Attack feat or the expeditious skirmish ability, and are under the effects of your racial burst ability during this full attack action, you may move up to your speed (including the additional speed from the burst) before, after, or in between your attacks this round, and may split this movement up as desired.
