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.
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.
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.
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.
