This set comes with five new heroes with which you can go a dungeon-crawling. But new heroes also means new challenges. The set also comes with two new Bosses, each with their own special dungeon tile (one for Level 1 and one for Level 2 of the dungeon).
And while Masmorra, itself, isn't an expansion of Arcadia Quest, this set does include stat cards so you can use the heroes from it in games of Arcadia Quest.
13 days left in the campaign and they've already made it through a bunch of stretch goals.
