Steps to reproduce

!additem Jolt_Axe !additem Jolt_Axe Equip both axes and use one. Use the other. You will see the item effect lost during onItemCheck, then gained again during onItemUse. Remove either or both Axes and the buff stays.

!additem Vision_Ring !additem Vision_Ring Equip both rings and use one (Ring1). Use the other (Ring2). You will see the item effect lost during onItemCheck (Ring1 buff lost), then gained again during onItemUse (Ring2 buff gained). Remove Ring1. Lose Ring2 buff.

Expected behavior

Enchantments should be unique per item if the item does not have restrictions preventing more than one from being on, including but not limited to Vision Ring, Mighty Ring, Jolt Axe.

• Using the item should give the associated buff, that instance of the buff should be lost when the item is removed.
• The unique instances of the buff should stack.
• Jolt Axe Capture
• Vision Ring Capture - Pending
