I just completed a 2x knight, 2x white wizard run, where the primary rule was never running from a battle. Would I describe it as challenging? Maybe, in that it’s unreal just how often enemies land persistent status effects that require post battle attention and/or instant death effects. I suspect that the game was balanced around running, so the result was quite a slog of an endurance run. Marsh Cave stands out in particular. Other rules for the run included fully gearing out at every town, including 2x Knight Armour in Melmond for 72k. I class changed at level 31 of 99. This is Steam’s Pixel Remaster. While at no point did I ever feel I was going to lose, the sheer volume of battles and the drain on resources was a different sort of challenge. I enjoyed it.
