From what I hear, it's real time. I'm not in-game to confirm. We need a chart containing the last known spawn, much like how the outdated Dungeon Respawn has one...
I didn't mean ingame or real time, I meant when? Every four hours means three hours are skipped per cycle, so which hours are the On hours and which are the Off hours?
Tarlach spawn time on 1, 5 and 9 AM/PM.. give or take!
