Cinderbrew is a controlled-space dungeon. The group needs to know which ground effects are being deliberately used, which adds must die, and when barrel damage becomes lethal.
Brew Master Aldryr: resolve Happy Hour immediately: At 66% and 33%, grab a Mug of Cinderbrew and use it on the enraged Thirsty Patrons. Leaving them active extends group-wide Rowdy Yell damage. Keep Hot Honey and Blazing Belch out of the stack point.
I'pa: kill Brew Drops together and move out: Defeat Brew Drops before they reach I'pa, but group their deaths so the Oozing Honey zones are manageable. During Spouting Stout, use a defensive and leave the resulting ground clear of the next movement lane.
Goldie: break barrels one at a time: Use targeted abilities to clear a controlled number of barrels. Each Volatile Barrel adds Cindering Wounds and waves; clearing too many at once creates damage the healer cannot stabilize before Let It Hail.
These are execution priorities, not a fixed pull-count route. Verify weekly tuning, affixes, and your tank's route before the key, then use the source and current videos for difficulty-specific details.
Boiling Flames is the first named interrupt in the Aldryr wing, and Erupting Inferno requires a quick dispel. Build the pull around that pairing rather than spreading stops across harmless casts.
