[RMVX ACE] ITEM RESTRICTION

Okay, I am beyond desperate. I've been working on this for three days. I've tried finding scripts, tutorials, I have used conditional branches and variables in vain.

You know how only magic users can learn magic? Instead of having magical skills being innate in my game, I want characters to have to learn magic from items. These magic spells and books are scattered throughout the game. I can make all of these items I want. But my non-magic users can use these items, of course, removing them from possession, though not learning anything, AND THERE IS NO FUCKING WAY TO FIX IT!

How can I keep certain characters from using certain items? If it were any other RPG Maker, I could just uncheck his name. I'd love to be able to define who gets to use what item.

Thank you! Having a lot of trouble making it work. I'm talking to Hime about it. It doesn't seem to want to obey the tag conditions. It just turns off the item for all actors no matter what.
