bamboo Staff or Just Staffs.

Staffs, could work by or rather a special function of the staff could be for making the knockback vertical or being able to actually knockback players more vertically. thier could be different variants too, like a bamboo staff, n'such as well. they could offer or do other things as well, or like damage or other things. perhaps even the bamboo, like copper, some of them could age or "degrade" or whatnot, turning more a brownish color.
