Armor upgrading system

You can use the item tooltip plugin to add stats and other info in an items description.

I feel like the videos pretty clear. You would need to make a new crafting block with all your necessary inputs. Then you would make seperate items for every possible combination of items. That way you can change the armour values through the properties depending on the combination.

You would also need to make crafting recipes for every combination. You would have to do these through procedures and not through the recipe element. Use the template procedure 4x4 crafting recipe as a start and then go from there. That template would be for a single item so the procedure will be long. Therefore it would be better if it was button activated.

Well in the gui menu you add a button, then the long recipe procedure is activated from that button.

I dont know anything about the tooltip plugin other than it exists.
