Lord Rhyolith is a fiery giant, and one of the bosses of the Firelands raid. Sadly, when fighting Lord Rhyolith, ranged DPS don’t get the fun job of steering the boss around the room – instead you’ll be responsible for damaging the various adds that will spawn during the fight.
During the main phase of the fight, Rhyolith won’t be doing any direct damage to the raid. Instead, he’ll wander around the room under the subtle guidance of the melee DPS – read our guide to fighting Lord Rhyolith as melee DPS and our main article on Lord Rhyolith tactics to see how it works.
Lord Rhyolith actually has three unit frames – one for his body, and one for each of his feet. Although your main job is to DPS the adds rather than the boss, you may occasionally find yourself with some downtime, at which point you should feel free to hit Rhyolith. If your aim is just to damage him, always target his body, rather than his feet.
Your raid leader may occasionally require you to join the melee DPS in applying damage to one of Rhyolith’s feet – this is what steers him in a particular direction. You should only ever do damage to one of Rhyolith’s feet if specifically requested to do so. Make sure you’ve targetted the correct foot!
Rhyolith will summon adds approximately every 25 seconds. These adds will be either Fragments of Rhyolith (in which case 5 mobs will spawn at once), or Sparks of Rhyolith (in which case only one mob will spawn).
Sparks of Rhyolith throw out constant AoE damage, so your tank will move them away from the raid. You should DPS them down as soon as they appear. Sparks gain a stacking buff which increases the damage they do, but also increases the damage they receive – so the longer they’ve been active, the faster they’ll drop.
Fragments of Rhyolith do comparitively little damage, and should be taken down with AoE damage. The important job here is to make sure they die within 30 seconds of spawning. Any Fragment left alive after 30 seconds will rush at a random raid member and explode, doing some nasty damage. Fragments are priority targets over Sparks: they need to die, and die fast.
There’s fire on the ground. You know what to do.
Rhyolith will cast Concussive Stomp every 30 seconds. As well as dealing out some raid-wide damage, this ability will create volcanoes on the ground. Volcanoes will occasionally erupt, dealing fire damage which will be spread among the raid at random. When Lord Rhyolith steps on a volcano, it becomes a crater, and those are the things you really need to watch out for.
As soon as a crater is created, it will emit Lava streams. The streams will start at the crater and move outwards in all directions. Don’t get in the way – if you stand in a Lava stream it will do what fire does best and burn your feet off.
After 10 seconds, the streams will explode, doing damage to anybody stood in them. So, once again: do not stand in the fire. The streams don’t move very quickly, so as long as you’re paying attention you should be able to avoid them.
When a crater has finished spewing lava, it will become a lava pool – a pool of fire on the floor which you should, that’s right, not stand in.
Phase 2 begins when Rhyolith reaches 25% health. He’ll discard his armor, assume his true form (spoiler: his true form is fire), and attack the raid. Your job here is simply to DPS him as fast as you possibly can. He won’t summon any more adds, but there will probably still be fire on the ground, so watch your step. Rhyolith will be throwing out increasing amounts of damage, so the sooner he dies the more likely you are to be alive to witness it.
