Über Chaos Sanctuary

I would like to see the Über Diablo world event turned into a player driven event similar to the Pandemonium event (Über Tristram) rather than a server wide event.

To obtain the items:
Any selection of “mini bosses” for the event that aren’t Act Bosses and aren’t used for the Pandemonium event (The Countess, The Summoner, and Nihlathak):

Blood Raven in The Burial Grounds
Griswold in Tristram
The Smith in Barracks
Radament in Sewers Level 3
Izual in Plains of Despair
Hephasto the Armor in The River of Flame

Each “mini boss” selected for the event would have a chance of dropping an event item unique to that boss. Similar to how The Countess does not drop a Key of Hate.

When the conditions are met and the event items are transmuted in the Horadric Cube, a portal to The Über Chaos Sanctuary opens.

The portal is made in Act IV Hell via the event items in the Horadric Cube.
One portal per game.
Must complete Act V Hell to open.
The portal leads to the entrance of The Über Chaos Sanctuary with these Über Bosses:
Über Lord De Seis
Über Infector of Souls
Über Grand Vizier of Chaos
Activate the 5 seals to summon:
Über Diablo
