The first boss’ electrocution is a line AOE cast at each player, and the damage can stack, so it’s best to lightly spread. Also, the adds have very low health (WHM here, soloing them is easy), so I’d leave the tank tanking.
The second boss gains stacks equal to the amount of poison clouds on the field. The mustard bomb will eat four before self-destructing, giving everyone four stacks of poison (which is about 2k per tick). With good DPS, can rush him down without ever dealing with the bombs, but otherwise killing one at two or three stacks is a good idea.
Finally, the sleeping dragons don’t hit particularly hard. They aggro if you come close, open the chest near the second one, or if you kill one of the babies within a certain range of them; the scream wakes them. The range is such that if you pull the first babies onto the “web” or whatever it is, the scream won’t reach. Killing them isn’t bad, as they really aren’t that strong, and they give a lot of experience.
We’ve actively tried to kill ourselves multiple times in the place, so we know a good bit about it. For example: killing Estinien doesn’t remove the debuff on Nidhogg; it instead causes him to jump away and instant-cast Massacre. We were very disappointed that we didn’t get to fight a crazy powerful Nidhogg.
I know that when the waves of adds pop on the last boss that tries to attack our dragoon friend, it’s good to lb the last big dragon while Nidhogg is casting his wipe aoe. I ran this as nin, and the other dps, a friend, was bard. I also found it easier when you’re trapped in the sir, before you get trapped, move to someone who can get you down asap because if you aren’t cut down asap you die, I also found it easier to keep an eye on and heal or dragoon friend through out the fight since he will take the aoe damage from the orbs placed. Took about 4-6 wipes before we found a good position off to the side of our dragoon friend that was far enough so he didn’t take that much damage but was close enough for our healer to keep him up. It was a painful fight but once you get it down and know what you’re doing then it’s easy Thank you for your awesome dungeon guides and entertaining videos!!
From what I understand, each poison cloud up gives the second boss a damage stack, so letting a bomb eat them makes the boss do less damage. But of course, you want to make sure it doesn’t eat too many and kersplode.
In the areas with the baby dragons and the sleeping dragons: the baby dragons will emit a non-damaging (or very slightly damaging) aoe when they die which will wake the sleeping dragon if they get hit by it so tanks should take care to tank the baby dragons away from the sleeping dragon.
