Just wanted to let some people know that the quest for the 3 delves is 3 different delves, not 3 of the same one. I should have figured that out when I did my first 2 that I can comfortably solo at T8.
Oh fun fact, I found another one today that I can solo well, so that brings me up to 4 that I can do at T8!
So yeah, just in case is someone out there was as stupid as me an decided to do ECMs again for giggles an stuff.
