As we don't have any clue about Behemoth/Odin spawning timers, I'd like to keep a log of their appearance so that we can try to figure out if there's a real timer of if it's totally random.
I'll post the ones in wich I actually took part (in Ragnarok server) and you can add yours as well so we can compare our data.
Behemoth:
15/09/13 9:45 GMT
Odin:
