I get it that in offline, single player mode, selling a SOJ causes the Diablo clone to spawn. Does the clone stay active if you don’t kill it, exit the game, and return?
Nope, that is a lost SOJ.
What got me thinking about this, I had a momentary power outage while playing last night, lost the connection. When I eventually logged back on, everything new I had farmed was lost. If that happened after selling an SOJ I would have been really pissed.
Similar but not related to SoJ, I dropped a 5 or 6 +life/mana charms, a +1 skills amulet and a +109 mana ring out of my inventory to make room for a bunch of gems from my stash to more easily combine them and the server lost connection. I was so pissed, mostly about losing that +1 skills. Guess I will put stuff like that in my stash next time.
The worst part of my tale of woe, I had an unidentified unique ring, it could have been a SOJ!
