So what is it? Arena is a place where you can battle other players without consequences. Your corpse won't get looted, and you won't drop a level. Developer Jason Bender said they may be supporting leaderboards and other ways to rank players in the Arena, but you won't be heading in there to find epic trinkets. "We don't want this to be the way you get loot," Bender said. In fact, the only real consequence of Arena is the hardcore mode, where if you fall in battle … your character gets erased forever. It's pretty much just for bragging rights, but Bender said they may explore some way to entire players into Hardcore Arena battles. With Battle.net and their love of decals, I imagine that's where something will appear.
