The Arcane Hallows update makes the sequel a bit bigger than the first game.

The Arcane Hallows update also adds a lot of other stuff, I'm just excited about the guns. The assassin class from the original Rogue Legacy makes its return, as does the architect NPC. The architect allows you to preserve the structure of a previous run at the game in order to perfect yourself against a layout—or go back to retry a fairy room. New curio shops also appear, allowing you to buy things mid-run.
The center of the Arcane Hallows update is a new region of the castle, the Stygian Study. It's not all books, though: There are monsters trying to murder you and a new boss there as well. I like the new enemies: Killer scrolls, paintings, and mimic treasure chests. I do love a good mimic.
