I tried it, around floor 48 where Vishno spawns, but they never came to… :itsamystery:
"I just did this the other day, and I was having the same problem. What I noticed was that there were a lot more Deidars on the higher floors. Then I just went back down (without actually exiting the area – I didn’t use any waystones or anything) and back up and Vishno was there. I was counting as I went, and I think there were a total of 12 Deiadars that I killed."
