I'm trying to set up my weapons so that certain weapons work better when equipped to certain characters. weapons can be equipped to anyone but for example, fire based weapons are stronger with character 1, ranged weapons work better with character 2, and so on and so on. does anyone know how that would work out. thanks.

The most simple and understandable way of doing this is Via common event, similar if you're going for say, an item which increases your Maximum HP or MP. Common events are the way to go.

Cool. thanks
