I'm not very good at this game.
I seem to be following the same pattern every time, I get to about 450ft and get surrounded by orcs and can't do enough damage to ever clear them, gradually having my health whittled down to zero.
I tend to bung most of my starting points into melee, evasion and perception and then take Focused Attack and Concerntration to help clear early monsters away. Later I get Keen Senses and then Parry if I find a defender or Blocking if I find a good shield. Then I tend to up Evasion and Melee to try and counter the inevitable orc rush.
By the way, I would have expected Inner Light to counteract the darkness from shadow moulds, but it doesn't seem to make any different.
Also I got boots of Soft Tread <+3> but they only seemed to add +2 to my stealth score. Is that a bug or am I missing something?
