An engineer can modify items for the following slots to have have an on use effect: Head, Back, Hands, Belt, Feet
It would be rather useful if LunarSphere has Use: xxxx options like there are for the two trinket slots. Right now, I either have to drop the item into a LS button and remeber to update it every time I change gear, or I need to have "/use #" macros for each slot.
The Use: Feet option would also cover the Ruby Slippers from Karazhan.
/use slot numbers For reference:
- Back: 15
- Belt: 6
- Boots: 8
- Head: 1
- Hands: 10
- Main Hand Weapon: 16 (Yes there is at least one MH weapon with an on use effect)
Come to think of it there are a couple of tabards with on use effects as well as at least the Dalaran rings. Offhand, I can't think of any other slots that have items with on use effects.
