[color:"orange"]To finish at that level must mean only doing the main story line[/color]
Yes, she only fought when absolutely necessary (using a survivor for the Sneak ability), completed as few quests as possible. She did get go through the catacombs and cure Mardaneus, part of the main plot, but which people have since discovered will not break anything critical if skipped.
She could not use scorpions (etc) most of the time, because she could not control what they attacked. Fights could be quite long and tedious, due to having a much lower level than the bosses she had to fight (low stats and poor equipment). Fighting the succubus at level 5 or 6, her chance to hit was small enough that she would save after getting a successful hit, so she wouldn't loose that progress if she got killed (she missed something like 4 out of 5 times, or more, and could be killed in 1 or 2 hits).
Once Areana got to the wastelands she quit. By then she had proved her point, so to speak, and set a record. Finishing the game would have meant more tedious fights with Black Ring members she had already fought once.
I do not recall if Areana went after animals for the meat, or avoided them for the unnecessary experience (though after you go up a couple levels the experience you get for them starts dropping). She certainly took advantage of any bread and meat she came across, though.
Arena confirmed that character level influences stats of equipment. The higher your character level, the better the chance stats will be in the upper range of what is possible for any particular piece of equipment. She tried the holy item quest at level 5, hoping to get a Frost sword, but gave up reloading after a fair bit of time. Coming back to this quest around level 8 or 10, she found it much easier to get acceptable stats on the holy sword (though she didn't get Frost).
[color:"orange"]if you never cure Madarious (sp?) well he show up cured in the later quests or won't he show up until he is cured?[/color]
When you scry for the human council member and leave the council hall, Aleroth gets reset for the orc invasion. Mardaneus' house is locked, the ladder in his cellar removed, and if he had not been cured yet, Demona apparently knocks some sense into him. <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
Once person who had not entered the catacombs experienced problems after scrying for the human council member; once they left the council hall, they could no longer save. Opening the catacombs before scrying avoided this problem, however.
