Psychic Strike (Su) As a move action, a soulknife of 3rd level or higher can imbue his mind blade with destructive psychic energy. This effect deals an extra 1d8 points of damage to the next living, nonmindless target he successfully hits with a melee attack (or ranged attack, if he is using the throw mind blade ability). Creatures immune to mind-affecting effects are immune to psychic strike damage. (Unlike the rogue’s sneak attack, the psychic strike is not precision damage and can affect creatures otherwise immune to extra damage from critical hits or more than 30 feet away, provided they are living, nonmindless creatures not immune to mind-affecting effects.)
A mind blade deals this extra damage only once when this ability is called upon, but a soulknife can imbue his mind blade with psychic energy again by taking another move action.
Bladewind (Su)
At 9th level, a soulknife gains the ability to momentarily fragment his mind blade into numerous identical blades, each of which strikes at a nearby opponent.
As a full attack, when wielding his mind blade, a soulknife can give up his regular attacks and instead fragment his mind blade to make one melee attack at his full base attack bonus against each opponent within reach. Each fragment functions identically to the soulknife’s regular mind blade.
When using bladewind, a soulknife forfeits any bonus or extra attacks granted by other feats or abilities (such as the Cleave feat or the haste spell).
The mind blade immediately reverts to its previous form after the bladewind attack.
