Been stuck on 1-7 for 3 days. Pretty much getting tired of trying. ONE time I got to 45%, every other attempt has been between 1% (srs) and 35%. I've tried your picture method, i've tried the right side, I've tried meteors instead of rigor and also druid instead of vlad.
160* PD 9/10, 4/8 revit, 2/5 revive
150* Druid 7/10, 4/5 zerk 3/5 slowdown
160 SM 6/10, 4/8 zerk, 2/5 wargod (I just recently started using him for dungeons to improve odds. While I know he's weaker with the 6/10, my resources are currently into mino)
179 SB 8/10, 3/5 revit, 2/5 wargod (put the 3/5 wargod on mino for dungeons)
178 Cupid 8/10, 4/5 revit, 2/5 revive
156 Mino 7/10, 3/8 tenacity, 3/5 wargod (I got him about a week ago, was born with talent and about halfway to 8/10)
Other heroes I sometimes swap to:
165 Vlad 8/10, 6/8 LD, 3/5 bulwark (used him to clear expert and insanes up until 1-7)
178 TG 7/10, 5/8 wargod, 2/5 zerk
I know I have the heroes for insane dungeons, just underleveled but I'm strained for resources atm. Can probably get mino and SM to 8/10 in a week in half or so, I'm currently farming R with only those 2 to level them up.
Anyways, I'm getting tired of doing this dungeon. I was cursing up a storm on the ONE time I ended with 45% (that was using meteors and going left side).
Edit: right after this post I blew through 1-7 and 1-8 lol <_<
750 Flamed Achieved 2/10/16. Too lazy to re-max.
