LV1 move: an extremely thin but unbreakable bone needle shot from the ranged form of Hachi's bone weapon, due to the rather small size of the attack, it's very hard to see and even harder to get out of the way. downside: has to be used with a weapon
perk: Untrackable (sight speed -0.3 to see the attack)
EDIT: X4 use, per neji's instruction
