Staff weapon locks[Resolved]

Is it fairly doable to make staves have weapon locks to particular characters? Like for example making only L’Arachel (and not any other staff users) able to use Latona.
I tried fiddling around with their locks but it seems like making them not able to be equipped and/or greyed out on the character’s inventory doesn’t stop them from using the staff…

Edit: Solved.

Staff/Use usability is different from normal usability. I still have yet to implement dancer ring locks for @ghast. Currently, there’s no way to do this. But maybe fiddling around in the staff usability…?

Maybe if you make the Staves equipable like in FE10 the Venno’s Lock array may work… probably.

Staff effects den’t depend on being equipped.
