Sole means you, and
only you. No NPCs. Nope, none, nada, no-no.
How, why do we do it? Well, that will be because we have played the game as a party too many times already, seen practically everything that there is to see, and want a new challange. We fully exploit every single advantage that we can get out of the game, in order to succeed. Oh, and in case you are wondering, we do not cheat in order to make it possible, at least I know I do not cheat.
You are only a nut to solo, if you have not played a party through the whole game yet. As I mentioned before, we do it for a challange. Soloing is
NOT by any means a walk in the park. We know what to expect, because we have completed the game numerous times already.
Monks are viable soloists, and rank up there with the Sorcerer as one of the best
pureclass characters to solo with. Dualclassed and Multiclassed characters are also viable, but they are too many to specifically mention a few.
