Im trying to make a shield via items. The shield has a finite set of charges. You can buy more at the shop. The shield will activate when you are taking deadly amounts of damage.
I have tried to make a dummy effect and an ability and reduce number of charges via an effect, but the item still stands untouched in my inventory. I have tried to use the behaviour charges, but it seems it has no effect on the item.
How would you go about doing such a item? Anything i might be doing wrong?
