Spoiled Goods

EDIT:

My comment is outdated. See the other comments. In my opinion it still remains the worst achievement in WoW, maybe 5k PvP pet battles is worse, but thats it.

This is the worst achievement in the history of World of Warcraft. At least in my opinion.

How this even got through beta is beyond me and the only reason there are not more comments here is because everyone is afraid more people will know about this chest. But I don't care because i will ignore it from now on till it is completely reworked.

Every 6 hours (yeah, lol) a chest appears in one of the four zones. Which zone it is is random (of course it is because duh). The chest is marked on the world map and can only be looted by 5 players (of course because this seems to be fun, right?). So the chest spawns at 6 a.m., 12 p.m., 6 p.m. and midnight (yeah like the perfect times to play for any healthy human being). You get a casting bar when you attempt to open the chest, so you can't just sneak in there and open it quickly.

So what happens is that you get like 500 groups fighting for minutes over the chest until it despawns or one massive raid wipes everyone so that a selected few can loot the chest (good times being a streamer).

Like who designs this and thinks "yeah man, thats fun, ship it like that". It is absolutely insane to me this released like it it is. It realy shows that there is no QM anymore at blizzard.

I fully expect to have to wait until the next expansion before I even have a chance of getting this achievement. The entire "event" is just bad and a terrible experience. At this point, it would be better not to have the chest and its associated achievements in the game at all. It's that bad.

Do yourself a favor and don't even try getting this. It will just ruin your day and waste your time. And as long as you don't have a massive raid to ensure you, and only you, loot the chest you have no chance on getting this chest. So don't try it and stop wasting your time.

So, the chest does not appear in a random location, but is tied to the Shadowlands pvp locale
Ardenwald - Dorne
Maldraxxus - Hallowfall
Revendreth - AzKahet
Bastion - Ringing Deeps

Finished this today and want to piggyback on previous comments, add some input, and clarify a few things here.

1. Unbound Spoils spawn 4 times a day, once during every 6-hr intervals, starting at daily quest reset. (E.g. For NA, 1st spawn during 7am~1pm, 2nd spawn during 1pm~7pm, 3rd spawn during 7pm~1am, 4th spawn during 1am~7am)
Find those locations here.

2. Contrary to some previous comments suggested, the chest does NOT neccessarily spawn at 7 o'clock or 1 o'clock sharp, but rather randomly during the 6 hour intervals stated above. It can spawn on the hour, but it may not.
This makes farming unbound spoils very time-consuming.
Over the past 48 hours, I have seen chests that spawn on reset, ~45 mins in, ~1.6 hrs in, ~2.5 hrs in, ~3.6hrs in, ~4.4 hrs in.
Nonetheless, they never bugged out and not spawn.
(yes, I slept very little to figure this out, and I'm dozing off as I'm typing...)

I think the spawn timer confusion stems from the fact that some commenters are lucky enough to see multiple on-the-hour spawns, and its easier to believe this is a fixed-time spawn. However, the timer is actually random, hence the conflicting reports of random sightings of chests.

3. The spawn location is tied to active Shadowlands PVP quest zones, which means the spawn location is predictable. (Big thanks to clancyBY for this amazing discovery, absolutely goated)
Ardenweald - Isle of Dorn
Maldraxxus - Hallowfall
Revendreth - Azj-Kahet
Bastion - The Ringing Deeps

Given this linked relationship, important inferences can be made.

a) Check which Shadowlands PVP quest is active now, you can go camp out the corresponding map, the chest might not have spawned yet.

b) At 7 o'clock and 1o'clock, check which Shadowlands PVP quest is up next, and you can use dungeon teleports to quickly move to target location, in case its an immediate spawn (E.g. Ara-kara for Azj-Kahet, Priory for Hallowfall, Darkflame Cleft for Ringing Deeps).

c) Unbound spoils will never spawn in the same zone consecutively, just like Shadowlands PVP quest will always change zones when one expires.

d) The Shadowlands PVP quest zones make a full rotation every 24 hrs, so does unbound spoils spawn locations.
Therefore whichever zone it is active now, it will be greyed out for the rest of the day. (A day's start defined by daily quest reset)
Given the first 3 spawn location of the day, the last spawn location of the day is always known beforehand.

Happy hunting.
