Boss Fight
Use Heroism/Bloodlust at the beginning of the fight. Your raid leader should have split the groups into two, having healers and DPS on each side. The boss will put circle debuffs on players which shrink over time. As they shrink, they will deal more damage. Have these players stand behind or to the side of the groups.
The boss will occasionally have his tail grow behind the players and mark a shadow on the floor. After a couple of seconds, it will slam down killing anyone under it and shooting waves of lava in either direction. There will also be puddles of lava spawn throughout the fight to avoid.
When the boss reaches 100 energy it will begin to cast Flood of the Firelands, and two large soak circles will appear. Your groups should split evenly into each and position yourself to get knocked the direction you are moving. After this happens, lava will quickly spread across the floor and the boss will begin to cast Serpent’s Fury. This is a good time for your healers to use their cooldowns and the rest of the team should stack and use defensives. Shortly after this the cycle repeats again until either the boss dies, or you run out of space and the boss reaches its enrage timer.
Mythic Difficulty
The main difference in Mythic difficulty is When Coiling Flames finishes it becomes a group soak that you need a few people inside very quickly before it hits. Having a rule for when the tail appears which way to run will help the group with positioning and remember to never stack the soaks at the end of Coiling Flames.

Hellboil

Flood of the Firelands
Each time Volcoross reaches 100 energy, he spawns two group soaks. These need several people in each to split the damage. It then knocks players from the centre and spawns Hellboil puddles on the floor that grow quickly. Volcoross always uses Serpent’s Fury after this.
Serpent’s Fury
The boss shoots fireballs at every player several times over 5 seconds that needs healing through. Volcoross casts Coiling Flames on players during this.
