Just finished game - combat is completly unbalanced...
Guard - useless in any situation
Charge - is russian roullete, 50/50 to kill or get killed after dungeon lvl 5 or so.
Gear:
best weapon i found + 8 atack
best armor i found +5 def
Finished game as lvl 21 with 32 hp, hardest enemy normal attack hits for 30!!! dmg, and he has 127 hp.
So the only way you can beat this game is put ALL points in def and never use anything except regular attack, you need to grind some easier mobs aswell for 5 mins or so before going deeper each lvl.
Unless you think your lucky enough to make 1000 50/50 roll in your favour in a row you wont beat this game other way...
