The brewfest boss, Coren Direbrew, drops the equivalent of 41 badge trinkets. You might not want to pay 41 badges for [item]Gnomeregan Auto-Blocker 600[/item], but a couple kills for [item]Coren's Lucky Coin[/item] might be worth it. Or better yet, you can get [item]Empty Mug of Direbrew[/item] and save yourself having to buy [item]Bloodlust Brooch[/item].

Healing and spell damage trinkets also exist, if you want those:
[item]Direbrew Hops[/item]
[item]Dark Iron Smoking...
