4. Devouring Flame - Spits a Lava Bomb at a player, inflicting 6013 to 6987 Fire damage and deals 6013 to 6987 Fire damage every second to anyone staying within 6 yards of the explosion. This effect lasts for 25 secs. 

Strategy:

I have to say this is one of the most simple boss fights in the game.
The encounter starts when we talk to an NPC who will, along with his companions, repair harpoon turrets.  Total of 4 harpoon turrets must be repaired to bring the boss down from the air.  While he is in the air he casts Devouring Flame, which does initial fire dmg and puts a fire patch on the ground that does fire dmg every second if you stand on it.  Throughout phase 1 (while he is in the air), adds will spawn from the drills that come up from the ground, tank and dps needs to focus on getting them down while dodging Devouring Flame and the patch it leaves. Keep tanking and dps down adds till 4 harpoons are repaired and they will be used by the NPC's to bring the boss down. When boss is down on the ground, no need to tank because the boss will be stunned till be breaks from chain to fly up again. I dont know how long the boss will be down on the ground, but dps needs to go all out on him (save your cooldowns until phase 2).  Phase 2 starts when he is 50% health. Boss will be down on the ground and will cast Flame Breath occasionally which is a fire attack toward his frontal cone.  Again, tank needs to tank boss facing away from group.  Boss will still cast devouring flame so the raid needs to get out of it asap.  

Every time boss cast Flame Breath, he puts a debuff on the tank (assuming that the tank is the only one getting hit by the attack) which increases fire dmg taken by 1000 for 1 min.  Start of phase 2 is the optimal time to pop blood lust and cooldowns to get the boss down asap before tank gets too many debuffs stacked on him to the point where the boss can 1 shot the tank with his breath.  However, there is an alternative solution (not verified) where the off tank taunt boss off the main tank till debuff wears off assuming that boss is tauntable.

Other than that, dps hard during phase 2.  Phase 1 is tank adds and wait till harpoons finish repairing and getting boss down to 50% health to trigger phase 2.  

Here is a video, very simple fight.

Again 25 man  but it is no different in 10.
