5) Run all the way back to Lord Stormsong's room without fighting or touching any lingering trash.

6) You'll see two little braziers or small firepots on the left and right side of Lord Stormsong.

We only light up the braziers in the 3rd boss room and got the achievement.

Full credit to Linodas and his team for figuring this one out.

Near the start of the dungeon, in the very first room that you fight trash in there are 4 pillars. The one to your left as you walk in has a small interactable item called Shrine's Breath. DO NOT CLICK IT YET.

Throughout the dungeon, there are 4 braziers that need to be lit. When you pick up the Shrine's Breath, coming into contact with the brazier will ignite them. Once you've ignited all 4, you get the achievement.

The catch is that if you take ANY water damage while you have it, you lose the Breath. If you kill the first boss, the Breath will despawn and no longer be interactable.

What my group did was to avoid taking the Breath at the start and instead cleared literally every single trash mob between us and the third boss, skipping the first and second bosses on the way. It doesn't matter if you take water damage this way since you haven't picked up the Breath yet. Once you clear all the trash, return to the start of the dungeon. On your way back from the third boss, make sure you take the little portal sitting on a brazier between the second and third bosses. This portal will drop you near the first boss.

Get your Shrine's Breath, and sneak carefully past the first boss to the portal that brought you back. Before clicking the portal, jump into the brazier and make sure your torch lights it up. A little blue orb will appear in the brazier, and that means you're good. Once the first is lit, take the portal to the other side, and light the brazier you arrive at the same way you did with the first. After that, simply proceed to the third boss' room and light up the two brazier on either side of him. The achieve will take a few seconds to pop up.

Edit: As per Goldschakal, you only need to light up the two braziers near the 3rd boss.

My btag is FrostyShot#1667 if you have any questions about the metas. (US Servers)
