Currently trying to farm and get Sol (I have 1 Astra and 3 Luna...), I decided to farm Thabes Labyrinth. So I did multiples runs, staying for hundreds of turns in the last fight (until the Wheel stops working), but I don't see any of those "Balor" monsters. I read somewhere, on Gamefaqs I think, that Balor spawns in the last fight of Thabes Labyrinth but I never saw any!
Do you know on which spot (monsters always spawn on the same spot, in this fight) is he? Or, if he's not in this fight, where I can find it?
