This DLC is one of the better ones I've bought in at least the past year. It adds an extra gameplay mode, with 4 different arenas, and gives a good challenge. On top of that, you get some pretty damn good loot from the treasure rooms, even on the lower difficulties! 3-4x waves of 10 is enough to get legendary drops on aspirant. The tribute system lets you exchange tributes to get devotion points from something other than shrines, and the defense system is pretty cool. All in all, a nice addition to the game for a few bucks, and a great way to support the awesome developers at Crate.
