The Brewfest is currently live for testing on the PTR, and one of the biggest changes is the addition of yet another holiday specific boss, Coren Direbrew. Coren himself isn't completely new. He was also present in the Grim Guzzler last year, when he would give you a quest to deliver brew to the Brewfest and get an offhand tankard in return. This year, however, it appears he's a bit more surly. Instead of simply completing a quest, this time you need to fight him.
Luckily, the loot he drops is more than worth the hassle. Most of it is clones of the trinkets available for badges from G'eras, but there's also a couple other drops that look like a lot of fun. Overall, the loot should draw a lot of people out to Blackrock Depths to beat him up.
A list of his loot is coming up after the break.
