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.
