itch.io

Late to the party but if you want a lot of different weapons available for actual use by the characters then a plugin is the way to go. If it's only a few weapons  then it can be done within the database but it gets fiddly and less manageable the more weapons you add.

It's something I'll be looking at later for my game as I want to change the visuals for the sprites if they equip different weapons/armor. For me I'll have to use a plugin.
