A Greedy Emissary: Diablo IV Event

In a classic homage to Diablo, World of Warcraft is holding a special in-game event with hellish rewards!

Strange winds blow in from another world, and sightings of odd, bag-holding creatures spot the land. Find them and see what treasure they may hold!

When: May 25 at (10:00 a.m., Pacific) through June 14
Where: Across capital cities and Dragonflight zones.

The spreadsheet in the Wowhead article was created by Xirev-Vashj EU and the Achievements Discord, and it confirms the Treasure Goblin's spawn cycle. Image link from Wowhead.

This event is the source of Baa'lial, the lovely little demon goat that was datamined:



From reports in the EU, it has a decent droprate, and from Lazey:

Baa'lial Soulstones drop even if you've learned this account-unique pet. They are tradeable with eligible players (4 hours incl. time offline, no need to be in a group on kill), so help the more unlucky people with your duplicates or ask gently for one.

It looks like it's going to be a better version of Baa'l with a more useful ability set, so best of luck to everyone hunting down this pet!
