Cyrodiil caves' completion

victorred

I've been trying for a while now, but i can't find 3 bosses in Cyrodiil. I've been camping for at their suposed spawn points for long periods but I never find them. Is is bugged or something?

The bosses are:
Red Ruby Cave - Endare
Newt Cave - Gravel Tooth
Pothole caverns - Serrin Vol

I finished this achievement earlier this week, but it took weeks of checking the delves to find the bosses.

Some of the bosses have insanely long respawn timers, 4-8 hours. Other bosses appear to be tied to some NPC you kill, so I recommend trying to clear the whole cave and see if they spawn. Beyond that, you just have keep checking back and hope that no one has killed the boss in a while.

None of the bosses have long respawn timers.

What they have is the old school EQ mechanic:
Random chance to spawn on trash kill.

So to spawn them fast:
Group up, run around the dungeons in circles wiping out everything fast.

doing this with a 4man group of V12s destroying everything fast we made all 1-4 bosses spawn in every dungeon in less then 15min. (Almost none were present when we got in)

They do have long respawn timers. I sat in Bloddmayne cave, right by where Ironlash spawns for four hours while I was working from home the other day. No one came in the dungeon, I didn't kill any NPCs, and he just spawned. But whatever, I have no desire to argue about what I experienced, and I've completed the achievement already, so good luck in your endeavors!

Actually, all the bosses have around ~15 minutes spawn timer (or less sometimes). The problem is that only a set number of bosses can be up at any time.
Take Toadstool Hollow for example. There are 4 possible undead bosses + a spider boss at the start of the cave. Only 2 bosses spawn at the same time. If there are 2 bosses up, NONE of the other bosses will spawn UNTIL you kill the 2 bosses that are up. The bosses have a random chance of spawning, so you might have to kill the same boss over a few times before you get the one you want.
Most of the caves with 2/3 possible bosses only have 1 active spawn, so search the other boss spawn locations and if there is a boss there, kill it, wait 15 minutes and check the spawn locations again. One of the bosses will be up.

@SlasherZet That worked.
Was in Pothole Caverns. Just kill the one spawned boss and wait. Only one boss is spawning at a time

I just ran Pothole Caverns with another guy. We made many circuits CW and CCW trying to get Serrin Vol to spawn; over half an hour. We killed multiple instances of the other two. The only thing which worked was to camp on top of him. He spawned within five minutes.
