we are getting credit for killing the boss of the event, not sure on the next part ) i have mount from chest already. i had a player i left in maw from weeks back, i saw event was up, went to it, got a progress bar, was able to fill the bar and then the boss at end actually spawned and i killed it. so for now the event works, not sure for how long as this event broke many times during SL and DF, for TWW it has been broken for 1 year plus since pre patch.
the boss at the end is how you get https://www.wowhead.com/item=185973/chain-of-bahmethra chance from https://www.wowhead.com/item=185972/tormentors-cache
