Someone told me last night that:
1. Two Diamonds, three Gold Nuggets, 1 Blade
2. 9 with Ghost Hit
On 4. I actually wanted to know what the ganis look like, it looks like there's a forward-thrusting motion (more like a claw stab than a sword stab, know what I mean?) and a thing where you can flip the blade around in your hand... both have a shadow effect a la Johnny Cage in MK2 (anyone remember that?)
EDIT: Oh, yeah, what's Ghost Hit do, anyway?
