Requires another player in your game that has done the quest already.
You create the game, go to Tal Rasha’s tomb, and insert your staff.
When the door opens, TP back to town and have your friend kill duriel.
When he’s dead, go back in your TP, and enter the Duriel room. Go talk to Tyrael and he will open a TP for you.
You can now progress as normally, but the game will be bugged and Duriel will always drop first-kill boss loot like Andy bug.
Does this continue to work ? Or did they patch it like andy ? Andy no mater what… has same drop rate now
Vendors have been doing this trick for a while I’m guessing, with all of stock of TP scrolls they have. 
Had a recent quest kill on Duriel, 5x tp scrolls…
@ TheDarkJedi
Did that character do the durial quest glitch for permanent glitch ? Did yo do the create game with complete quest trick ?
No, but then again I don’t really care to glitch Duriel in the first place.
So now I can get even more town portal scrolls? 
@ Endz The glitch might reduce tp drop I cant remember.
