70 regular kills per walk? Nice cave!
Oh, the Circle Room is excellent for Guards, Geomancers and Soldiers. I did a video about it. But I noticed that the regular ones are curiously less easy to kill fast since the hoards of guards and soldiers are more dense. Kazz mines are also tricky due to the fact that we deal in tight corridors, so it is not easy to lure all of them in a fast way.
Thanks a lot!
