Start area
Skip the first two bridges, you can use
You will reach an area with two Molten Protectors, drag them with you to the next group of mobs where you can’t proceed. Kill everything there and the bridge to the Molten Effigy will come down.
Note that the Molten Protectors cast a zone which grants enemies inside
Molten Effigy
Stack
There is another single Molten Protector which needs to be focused before switching to the Molten Effigy.
Alternatively, you can use
The moment you killed the Effigy you can /gg if necessary so you don’t have to take the Mistlock Singularity (this prevents the problem where you can’t take the Mistlock Singularity due to being in fight), then you can continue to the next trash group. All following groups of mobs are progress-blocking, clear them to make it to the final area. Molten Protectors have the highest priority (because they cast AoE /gg once directly before the end boss if necessary.
Molten Berserker & Molten Firestorm
When you walk onto the end boss area, a group-wide
Kill the Molten Firestorm first and pay attention to the AoEs and Shockwave attack. Reflects are useful here as well (especially if you’re running without a healer). The Molten Berserker will heal to full health after his comrade is dead, kill him afterwards to finish the fractal.
Do not walk into the hitboxes of the two bosses to prevent them from moving out of damaging fields.
Advanced tactics for Molten Berserker & Molten Firestorm:
You enter the arena after killing the group of mobs before the bridge, before anyone enters the arena place a /gg fast, revive and take the portal to the Mistlock Singularity. It only works well if you know where you respawn.
After entering the arena again you kill the Molten Firestorm, then use /gg the moment it’s dead, this resets your cooldowns (after /gg the boss progress doesn’t reset so you do not have to worry) and you go back into the arena and kill the Molten Berserker.
