There are three of them in the lair
the rex
supreme
and prime
rangers attack the prime, melee attacks supreme, and mage attacks rex.
it's not wise to switch around, because only the one you're supposed to fight will you hit the most accurate on.

now for the lair
you have to go through a series of stairs to get to the actual lair containing these danagoth "kings"
The stairs is where you'll appear when you climb the final stairs to the lair.
Tips to follow for a sucessful trip:
1) Mages always go down first, they'll usually find themselves between all three danagoth; their goal is to lure the rex to the blue dot.
2) After the mages goes the melee, they attack the supreme and stay near the green dot. WHAT NOT TO DO: Never run to the red or blue dot, because it'll lure the supreme to range the rangers or mage.
3) Rangers go down last, depending on the speed they kill prime will determine what to do next. ranger's place is the red dot
4) If the prime dies before supreme, the meleers can now change their prayer from protection from magic to range.
5) if supreme dies first, then i guess meleers can go help the rangers kill the prime.
6) if supreme dies first, have protect from range on when it respawns and hope you kill it before the prime spawns.
7) don't worry about the rex, he'll spawn only at where its labeled "rex" on the picture, the mage's goal is to get the rex's attention and lure it away from the rest of the group.

one final thing, the rex attacks with melee, prime with mage (i've seen it hit 50s, can easily two hit anyone, and supreme attacks with range)
9) If prime is alive, no matter how hard supreme hits don't change prayer!
if you know what you're doing, you can protect range when prime is not focused on you; but it's not recommended.
Teams:
the best put together team consists of only 1 mage, two rangers and two melee.
mage keeps drop from rex, rangers share drop from prime, and melee share drop from melee.
but heck.. the more people you have the longer you'll last down there.
Note: this guide is not complete because I haven't taken the time to take picture consisting of those stair ways you have to go to actually get to the danagoth king lair.
Minimum amount people recommended is 5. (least amount of people needed to even get through the first part is 3)
