You'll want two tanks and 6 or 7 healers. DPS-wise, you want at least a few solid ranged DPS, but otherwise any mix of melee or ranged should suffice.
The fight is separated into two phases, although the real bulk of the encounter is in phase one. You've got two main goals in this phase -- controlling Rhyolith's movements around the room, and killing the adds he spawns from time to time. Rhyolith himself is not tanked in this phase - he simply walks forward at a fairly steady pace. However, if he should reach the lava at the edge of his platform, he'll actually drink the lava and then spit it all over the raid, causing an intense amount of damage that almost guarantees a raid wipe.
To keep this from happening, you'll need to attack his feet to steer him around the room. Dealing damage to the left foot causes him to turn left, and dealing damage to the right foot causes him to turn right. His feet are also the only way to actually deal damage to him during this phase, so even when you have him pointed in the right direction, you'll still want to be attacking his feet. We found it easiest to assign each of our DPS to one of the two feet. When he's heading in the direction we want him to, everyone just attacks the foot they've been assigned to, but when we want him to turn, the people assigned to the other foot simply switch over temporarily.
Periodically, Lord Rhyolith will use an ability called Concussive Stomp that deals a moderate amount of fire damage to everyone in the raid and also knocks anyone back who was standing nearby. When he does this, he'll also spawn a couple dormant volcanos randomly around the room, and every once in a while he will ignite one of those, causing it to become active. Active volcanos will hit up to 6 raid members every couple seconds for a small amount of fire damage, and also stack up a debuff that causes them to take additional fire damage. In order to stop them, you need to steer Rhyolith around and get him to actually step on top of them.
That not only puts the volcano out of commission, but also causes a couple other things to happen. The good news is, it'll break off a piece of his Obsidian Armor, which means he'll start taking a little bit more damage. The bad news is that it leaves behind a crater, which will occasionally send out streams of lava that cause a very large amount of damage. Fortunately, the streams move relatively slowly and are pretty easy to get away from as long as you're paying attention.
While you're steering him around the room, he'll also occasionally be spawning two types of adds. He alternates between spawning 5 Fragments of Rhyolith and 1 Spark of Rhyolith. These are what'll be keeping your tanks busy in phase 1. One tank should be assigned to quickly rounding up the Fragments of Rhyolith so that they can be AOE'd down. They don't have too much health -- only about 400k --, but if they're still alive after 30 seconds they'll deal half of whatever they have left as damage to a random raid member. Since there's already a fairly substantial amount of raid damage going out, that can easily finish someone off even if they're low, so it's best to just kill them off completely. In most cases your ranged DPS should be able to handle this themselves.
The Sparks of Rhyolith should be picked up by the other tank and pulled away from the group, as they deal constant AOE damage to anything within 12 yards. They'll also gain a stacking buff the longer they're alive that increases their damage, so these need to be burned down relatively quickly as well, although any Fragments that are alive should be a higher priority. Again, this is mostly the job of the ranged - melee DPS should stay on Rhyolith as much as possible.
So, to recap phase 1:
- Steer him away from the edges of the room and towards active volcanos by attacking his feet.
- When you don't need him to turn, split DPS evenly between the two feet. DON'T STOP DPS
- Ranged DPS: AOE Fragments of Rhyolith and kill Sparks of Rhyolith
- Don't stand in the fire!
Once Rhyolith, or I should say Rhyolith's feet, are at 25% health, phase 2 will begin. After a short animation, he'll do a fairly large raid-wide AOE, and one of your tanks should pick him up immediately. At this point the fight is basically just a DPS burn; he has a constant fire damage aura, and hits the tank relatively hard, but otherwise it's just a straight tank and spank. Adds will stop spawning, as well as volcanos, although any craters left over from Phase 1 can still spawn lava streams, so watch out for those. Just keep everyone alive, and hit him until he stops moving.
