I have a problem with VD7, it killed quite a couple of my PC's. Like right now, my GE Assassin, that had 10PV, died to a gelatinous cube form a tension room in VD7.
I was extra careful, i tried to gain range to shoot it, but it was too fast, then i decided to get it up one level to fight them one by one, to avoid getting surrounded while paralyzed but after getting the gelatinous cube up to VD6, i only got to hit it one time and ended up in a death screen.
What does this VD7 have so special about it that monsters generated there are so much more powerful than on other VD levels?
