@ Never There and Back Again: Had I to guess... I'd say memory editor >_> Or exploration mode, I guess, but cheatin's cheatin', official infinite lives or no
I'm not entirely sure how you'd go about it, really. It would require some pretty incredible shenanigans -- not only do you have to survive those first few bits (even the patrols have a minimum level way beyond a starting character, iirc.*), you also have to take on high peak with something like less than half the XP and loot chances you'd normally get.
It would
seem that four people have managed it, somehow, though. So it's either possible or they cheated. How... well, the winner list for those two classes is
fairly small larger than I thought. Let's scan...
... actually, I've now gone through the latest year's worth of non-dwarf/undead/yeek celestials, and whoever managed it innit in that lot. Someone else can look. I stopped at "DO YOU SEE THAT ENEMY OVE" the cornac sunpa, if said someone else wants to take up the quest to find Never There and Back Again.
*Actually, I can
check... hahaha, oh yeah. Well, okay, there seems the
possibility of generating, say, 10th level orc warriors! Good for you. Its
friends are in the twenties and over. Good luck with that~
