When you zone in, you will be on a translucent platform in the center of the one-room zone. There are four small circular platforms around the edge of the room (above a stripe of lava) and a switch rising up from the large middle floor.
You will fight a total of five creatures inside this zone, all of whom are Level 55 ^^^ very tall Efrit:
Activate the switch on the main floor to spawn four large glass bottles, one on each of the little satellite platforms.
Fighting The First Four
At that point, each of the first four combat cycles follows the same pattern:
1. Load the entire group onto one of the little satellite platforms. You can arrange your group onto any platform but you should get practice fighting with everybody in the same place, because by the fourth battle there will only be one platform left.
2. Click the bottle to spawn one of the first four Lords above. Over the next several seconds as you fight, the level of the lava in the room will rise to cover the middle platform, making the satellite platforms the only way to survive being in the room. ***IMPORTANT*** Once the mob has spawned DO NOT MOVE! Don't even jump! You may attack and use spells, but don't touch the movement keys.
3. As soon as the mob is dead, the room's lava level will reset, and the platform you're standing on will sink rapidly into the stripe of lava that's underneath it. You have roughly one second after the mob's death to leap screaming back onto the main floor area. The respawn point if not revived in the room is the teleporter area on Level 4 of Solusek's Eye, near where the Speaker of Fates stands. Corpses are placed on the rim of the main floor, and can be revived.
Fighting Djarn and Exiting
When all four bottles, platforms and Lords have been disposed of, a little disk will descend from the ceiling bearing a fifth glass bottle. When clicked, this will spawn Efreeti Lord Djarn, who is needed to complete the Saving Soles heritage quest. As before, the lava in the room will rise when the fight begins, so make sure you load everyone onto the little platform before spawning Djarn.
With Djarn dead, load everyone onto the little disk that held his bottle, and use the switch-on-a-stick to lift everyone up and out of the zone. Anyone who gets left behind because they weren't paying attention when the rest of the group climbed on and departed, can wait for the disk to completely rise, and then use the switch to summon it down again.
Note: killing Djarn will set an 18-hour lockout timer on the zone.
