How the heck do staves work?

I guess this is where my staff lord adventures come in handy!
@Teraspark has created a pair of ASM modules that help with creating custom staves!
Of course this is for use with buildfiles, I’m not sure how you’d do such a thing in FEBuilder.


@Venno has also done something similar, for both items and staves, but I haven’t used it so I can’t vouch for it.
