[Rataxes]

As I recall, my solo cleric beat SoA in just under 50 days, completing every single noteworthy quest available to him as well as every new encounter added by Tactics (including those connected to WK's exterior), but not the inside of WK. I think that is my shortest completion time for SoA, never intentionally tried to run through the game as quickly as possible though.

I wonder, how quickly could a solo Sorcerer beat both SoA and ToB? Since he wouldn't need to ever rest again once he gets access to Wish, which is pretty early on in a solo game, it could probably be done in less than 30 days if you don't waste any time travelling back and forth betwen places.
