Summoners War: Chronicles

Hey Guys,

ive tried for days now to hunt this damned water “Master Inugami” creature in Hero Area > Rudelin > Eia Hill, and it just seems to NEVER spawn at the given location. Its always the dark “Master Inugami”, but never the water one. Its really frustrating because thats the last creature gatekeeping me from 100% finishing my creature book! Is it a bug? Does he only spawn at specific times like 03:12am - 03:13am CET or some shit? I just cant wrap my head around this..

Did any have you found / killed Water “Master Inugami" once?
