I tried to find Jr. Balrogs but couldn't find even after many tries. I went to the temple in ch1 after sc, but I couldn't find. So I think Jr. Balrogs are not spawning.
Respawn timers are carried over throughout SCs. It has been killed and now you just have to wait for it to respawn.
Really? I don't think someone tries to kill all Jr. balrogs since it's far. After watching this thread(https://royals.ms/forum/threads/berserk-prequest-jr-barlog.60508/#post-319059), I guessed the way Jr. balrog spawns was different from other bosses and it's tricky. After 15+ hours from sc, I found some chs which there were no monsters on the path to Jr . balrog. That means no one visited Jr.barlog. But I still couldn't find it. I'm so sorry for suspecting, but it's hard to believe. Are you sure there is no bug about Jr. balrog? Or Can you tell me the respawn time?
Some cold/evil eyes were added to the map in old source which fixed the jr. balrogs from not respawning. Maybe new source doesn't have them yet?
