World Event is a new feature you can enable in version 1.36 of UVLod
To Spawn Uber Diablo you must sell 50-70 valid Unique rings in the game. You can enable the game to automatically sell rings for you, but to trigger that you must sell at least one ring.
The default Ring options enable Stone of Jordan, Raven Frost and Dwarf Star rings to count
towards SOJ's sold to vendors. You can enable some or all other Unique rings to count
as SoJ's sold to vendors, if you want.
AutoSaleSoJ
===========
If this option is enabled, the game will automatically sell a random number (1 to 4) "Stones
of Jordan" to vendors every (Interval) time period. To trigger Automatic Selling by the game, you must first
sell at least one Unique ring to a vendor from the list of Rings you have enabled.
Sold Rings Vanish Forever
=======================
If you enable World Event, and you sell a valid ring to a vendor, the ring will vanish forever. The only time this does not happen is after you see the message "Diablo Walks the Earth", and before you find Uber Diablo. After Uber Diablo has spawned the SoJ Ring counter resets to zero.
- This allows you to spawn him multiple times in the same game, but in this case, he won't spawn in the same place twice.
Where to find Uber Diablo
=========================
Once you see the message "Diablo walks the earth" Uber Diablo will spawn in place of the first
SuperUniqe monster that has not already spawned in the game. Popular spots to find him are, in place of, Rakanishu (Act 1), Eldritch the Rectifier (Act V), or any other place where a SuperUnique monster spawns close to a waypoint.
