Note #1: The [item=93195]/[item=93228] is account-wide and opens the Brawler's Guild for all of your characters.
Note #2: If you fail to get the bonus loot, the quest will reappear and you can try again.
Note #3: If the chain bugs and you stop getting missions (can be caused by using the mobile app), buy [item=143899] from [npc=70752] (A) / [npc=70751] (H) and defeat him again. The mission you were on should reappear in your list.

Quest is acquired from [item=142522]. Can get credit from watching other people brawl (potential bug?). Turn in to [npc=49889] in the bar area of the Brawler's guild.

Rewards 100 Brawler's Gold.

If you're doing on all toons possible to get the follower, and you've come this far, you can purchase first Boss' (Oso) challenge card in the instance, and use each time, untill you finish the quest, that it will still count. If you're having bad time doing the sequencial bosses, why not repeat the easiest first one, heh? Only 3gold per card.
