A small zone horizontally, you progress by opening up progressively lower levels down a central spiral ramp. Valves to drop the level of the lava become clickable as bosses are defeated. Entry is down an elevator outside the door to Deep Forge from Lavastorm. Click the lever to lower the platform once and go down hall to instance.
Clear the gnomes in the room, then turn the 4 steam vents to lower the lava and activate Fitzfangle.
Fitzfangle becomes active on the first level once all four of the valves (in each corner) turned. This also drops the lava and let you to progress to the lower level. Every 25% of his health he throws about 6 bombs, one at each member of the group. These bombs must be killed before they explode, or the AoE will be fatal. Jousting does NOT work
Having each member back off the tank a bit before each bomb percent and kill "their" bomb before continuing is one strategy, a better one is just to retarget "a bomb" and AoE / burn them, then back on to named. If you deal direct damage to Fitzfangle, he will detonate the bombs early.
Clear the room, including the roaming djinn on the stairs, then position 1 player at each steam vent and pull Ra'Zhish the Steam Lord to one side. During the fight, whenever the water level rises, click the steam vents to lower it.
Ra'Zhish the Steam Lord is an elemental, chained at the bottom of a pit ( -185, -113, 111 ) /waypoint -185, -113, 111. Initially non-aggro it periodically raises the level in the pit, causing nasty AoEs. A valve outside the pit at each end needs to be clicked to lower the level again. 2 ranged DPSers can do this from up top
Once dead, you go back up to the prior room and click the valves to drop the lava to progress to the next level.
About this time on the spiral ramp, you will fight an "enslaved lava golem" guarding a chest. The chest is not clickable yet, the key drops on the Magmadin level from "a sneaky goblin" About the spiral ramp mobs - they can be ranged, but will target one of the group with an aoe knockback, so stay close to the centre of the spiral, or jump down and melee them.
Clear the level and Jailor Ca'iluer ( -20, -192, -183 ) /waypoint -20.28, -191.90, -183.32 will flee from you until he cannot. Pull the mobs to either side of him first. They are social but can be single-pulled. When you pull him, during the fight he will summon flame whirls. Move back when he does this. After he is dead, open the jail cells and click on the drawing in either cell to burn it, revealing a tunnel between them. In the middle is a rock to sample and a red glowing key. Now you can click the steam vents (twice each, once to unlock and one to open) to lower the lava in the central shaft.
- Jailor Ca'iluer
Jailor Ca'iluer becomes active when mobs around him are cleared. Periodically he summons Flames of Ca'ilue. While the jailor is close to these, he has a stoneskin (which also can heal him), and they have a very large radius AoE that is small but constant so if you let too many of these pop up healers will have a hard time keeping everyone alive. So on each summon the group needs to move a bit. The summon can be interrupted with stuns/stifles/interrupts which prevents him from calling the Flames.
Once jailor is dead, 2 prison cells are unlockable. There is a tunnel connecting them, where you will find a key for the 2 chained valves up the corridors a bit ( -39, -193, -162 ) /waypoint -39.45, -192.59, -161.82, and a rock which will update the quest A Sampling from the Thexian Dragoon camp in Lavastorm mountains (near zone entry).
The 2 chained valves need to be unlocked (first click) then clicked again to drop the lava to progress to the next level.
Clear the level by going either way around the circumference, killing all Golems and drakota you find. Do this quickly as the drakota will respawn. Then go back to Magmadin and pull him. During the fight he will port all players into lava pools. Needless to say you need to get out of the lava as quickly as possible and rejoin the fight.
Magmadin periodically ports members of the group to the lava pools on each side (which have a DoT so don't stay in them). So the area must be cleared prior to fighting. Trash drakes repop, so don't take too long to clear. They do not see invisible.
There is a valve either side of Magmadin's location to drop the lava to progress to the final level.
The sneaky goblin roams around this area. See stealth (e.g. Vision Totem of the Cat totem) allows you to target / track him. Make sure you get the sneaky goblin before going to the next zone, as you will not be able to return once you defeat Magolemus. You will have to repeat the quest to get the shard chest.
Be sure to loot the shard chest before you begin this fight as the central shaft will be flooded afterwards.
This is a wave event. Originally everyone pulled the mobs to the stairs. More recently, the way is to charge into the room and fight there. During the first 3 waves flame whirls will be summoned. Move out of them to avoid extra damage. The fourth and final wave is The Reformed Magolemus who will get bigger as time goes on, so kill him quickly. Sometimes one extra wave of adds will spawn in the room after the Magolemus is killed.
To the left of the altar is a banner you can harvest for your home. If you all click together everyone can get one.
As a final parting gift, Najena floods the central shaft so leave quickly or use evac.
- The Reformed Magolemus
The waves are timed, so a low DPS group will still be fighting them when the Magolemus appears. The longer the Magolemus is up for the harder the fight.
After the fight there is a clickable banner behind her throne, which is a house item with some status reduction. If "clicks" are synchronised, everyone in the group can get one.
The lava rises shortly after this fight, so if you take any time to split loot or to cheer your victory, then the only way out is porting or evaccing. If you are fast, you can run out before the lava rises.
