You can have all 4 staffs in the "crazy place" charging at the same time
And if a zombie dies, its soul or "energy" will go to all 4 of the staffs without charging it any slower
The kimat's bite charge shot fires a ball of electricity that hits the ground and sits there for about 7 seconds and shocks all zombies that are already in the area aswell as zombies that will enter its range. Not only that but if you fire it outward (not hitting the ground) it will shock all zombies that it passes. Instakill till round 25
And there is actually 8 power boxes that spark. The last one is already in the correct position though, so i would see no need to have it in a wiki
And all Ultimate staffs have a special melee attack much like the thunder fist.upgrade
There melee attacks stop 1-shotting at around round 20
