So, I've spent about 7 hours in this game and dying at this point was really painful, after killing the DM-300 and surviving the dwarven city (which was incredibly hard) I died at the hands of some monk. No food, no health potions, nada.
I'm playing as a rogue assassin, I had got a level 8 evasion ring, which I was hoping would make it impossible for enemies to hit me. I also had level 2 plate armour with viscosity.
Looking back this was definitely my fault, I think I was too careless in the dwarven city. I lost two ankhs in one level.
Any advice?? This is the farthest down I've got.
Think of evasion as a nice bonus, not something to fully rely on. (And honestly same for armor, though it is more reliable).
For this boss specifically I'd suggest stamina potions, toxic essence to AoE deal with the majority of enemies and shrouding fog (2,2,3 just to be on the safe side). Also get stones of aggression for the final phase, and as general backups you can get stones of flock + shock for wand recharge or + psionic blast for straight enemy clearing.
Yeah!! I didn't really know how evasion worked. I kept cheesing enemies on the first levels like this and thought I had figured it out. But yeah, I need to revise my strategy
