Rygelon | Brewmaster Guide

Welcome to the Brewmaster Guide for Rygelon in the Sepulcher of the First Ones Raid Encounter! This guide contains Brewmaster-specific tips and tricks and is primarily geared towards the Mythic encounter, so don’t forget to check out Tanknotes by Panthea, or the Sepulcher of the First Ones Boss Strategy Guides and Raid Overview on Wowhead for a general overview of the mechanics of the fight on Normal and Heroic difficulties.

If you have any questions or feedback about this guide we’d love to hear from you! You can always contact us in the Brewmaster Monk section of the Peak of Serenity Discord server!

We’ll start with the boss directly on Star, and for each upstairs phase, move to the next marker clockwise. If your guild is particularly attached to starting in a different part of the room, you can start on any of the three markers, just as long as you’re moving clockwise each phase.

After the second set of Quasars spawn (about when the third Cosmic Core spawns) slowly move the boss to the area marked by the white circle for the appropriate section. Having the boss in this position when pushing into the next phase will ensure that your Unstable Cores in the downstairs phase spawn in the correct locations.

“Upstairs” Phase


As a Brewmaster, Celestial Brew offers us a lot of flexibility with stack order, since we can use it to prevent getting the debuff from Corrupted Strikes at all. The following order is my recommended taunt swaps to allow tanks to soak orbs without having to taunt the boss back and move it out of position, which offers some wiggle room for moving the boss away from quasars that aren’t dying in time. If you or your cotank is struggling with swapping in this manner, you can also just swap on every stack throughout the phase.


On Mythic, there are three sets of three Cosmic Cores that will need to be soaked. Each set will spawn with one roughly in melee, one roughly mid, and one roughly ranged. If swapping in this manner, your cotank should soak the melee core on the first set, and you should soak the melee core on the second set. This will line up so that you are holding the boss the entire time your cotank is soaking, and vice versa.

Use Ring of Peace to knock away any Quasars that get too close to the boss, but make sure that you are using it only when absolutely needed, as knocking away quasars can cause issues since they need to die at very specific times and locations.

Try and rely on Celestial Brew and trinkets to mitigate the damage in the upstairs phases, as your cooldowns will all be used to soak downstairs.


Each upstairs phase is exactly the same as the first,  so once you come back up, move the boss to the next clockwise marker, rinse and repeat. For the final upstairs phase, the entire outer edge of the room will be covered in puddles, so you’ll need to tank the boss a little closer to the middle. Bring it back to Star and get it as close to the edge as possible. The final upstairs phase is the main one you’ll want to be on the lookout for any quasars that need Ring of Peace, as there’s nowhere that you can inch the boss back to give them room to die.

“Downstairs” Phase


On mythic there will be three Unstable Cores that need to be soaked once they die. At the start, the ranged will go to the closer far core, and melee plus tanks will go to the core under the boss. There will be swirlies at the start of the phase that melee need to dodge, but feel free to stand in these as they don’t really hurt tanks.

You should start with the boss and take one stack, then have your cotank taunt. Shortly after, the ranged core will start to detonate, and you will roll over to it and soak it.

Depending on your timings, your cotank may take 1 or 2 stacks of Corrupted Strikes from the boss here. Aim for one, and if your cotank isn’t a strong class, you can taunt early and move the boss a little so that they only get one stack (just taunt right before the second stack).

After taunting, move the boss to the third core. The melee core should be detonating around this time and your cotank will soak it, then the entire raid will stack on the third core. You will then hold the boss until the next upstairs phase, so make sure you use Celestial Brew on either the first or second stack that you take.

When the third core detonates, your cotank should soak it and you should move the boss either directly towards the next marker, or if you need the extra DPS on the Unstable Matter, towards the closest matter so that DPS can cleave onto it while pushing back into the upstairs phase (only do this if your DPS on the Unstable Matter isn’t already too high).


For a cooldown rotation for soaking the Unstable Cores, you can use Dampen Harm > Zen Meditation > Dampen Harm, and save Fortifying Brew as a reactionary cooldown to cover any periods of high damage/unexpected low health at any point in the fight. However, this is very flexible and can easily be moved around depending on externals available to you in the fight. Brewmasters can comfortably live a soak with almost any cooldown, so if you are in danger at any point in the fight, don’t die without using something. You will likely be okay on the Unstable Core soak as long as you have any sort of healer external or defensive trinket like Blood-Spattered Scale.
