What about this zoning item?
UNIQUE PASSIVE: Upon dying, you enters a spirit form and deals 15% Max Health into magic damage per second to nearby enemies (600 range) for 7 seconds. (4 minutes cooldown)
For the build I was thinking about something like
+ 
It think it could be a fun offensive item for tanks/ap bruisers or even mages and maybe an intressting alternative for GA in certain situations.
#Some notes:
- You cannot move in spirit form
- You cannot use abilities in spirit form
- Sion passive will be tricky. So their are 3 options (1/ the damage remains on the spot he died, 2/ the passive stays on him (probaly OP), 3/ the item passive activates after the 2th time he died)
No, i'm finally cool now
