During the Captains event in Freeholder, the bartender Rummy Mancomb occasionally throws out small brown swirls that players can stand in (or avoid). He either throws out a significant haste buff / crit buff (desired) or a dot that does damage (not desired, but tanks can potentially move the Captains into the swirl and they'll take the extra damage).

It'd be super helpful in M+ to get timers or at least announcements when Rummy's about to throw out a swirl. If it helps at all, here's a WeakAura that tracks the event (would love to have it OOTB with LittleWigs instead of importing another WA).

You guys rock! Thanks so much!
