if a game says xxxxxxx sojs sold to merchant is it garunteed to be a dclone game and how long will it tke?

It is not guaranteed to be a dclone game. Depends on how many SoJ's were sold on that IP. Takes anywhere from 80-120 SoJ's to be sold on a specific IP for D2 to walk. Without knowing the exact count of SoJ's you don't know when he might walk or if he will even walk at all.

Sometimes it will say x amount sold to merchant over and over but only when it saya diablo walks the earth will there be a guarenteed anni in the game
