Area Bosses - Which is which and how to find them

And Im almost positive its 40. Just cause they spawn at 45 minutes, doesnt mean the spawn time isnt less; it just means no one was on the map when the spawn time was up. Also, Yeti's spawn time is 15 minutes and nowhere close to 45.

I'm not sure about Yeti, but Mano and Elija spawn in 45 minutes no more no less. I've spend days there.

Tymen.

P.s. I cycled the channels from 9 to 8 and then waited for it to spawn in 9 again.
I've timed Yeti and it's either 14~18 minutes or 14 or 18 minutes I think the last one cause the ones I timmed where around 14 or 18 minutes.
