Sorry, but the game im making doesn't use FL's weapon system, if it did it would a hell of a lot to trigger.
If you want to make items then make then increase/decrease Atk speed and add a certain amount of damage.
You can only have one weapon in ur inventory, and one armor, and one book of spells, the other 3 slots r for any other items you want, boots (only one of them btw) or potions or even artifacts.
