So, there are a few houses out there in the Spiral that have a special feature that gives a free loot roll on a daily basis, like the Minotaur at the end of the maze in the Aquila Palace or the Genie from the Sultan's Palace . . . or my favorite:
I love that Gorilla! I don't know where he gets these presents from, and I don't know if I want to know!
But, because that free daily loot roll exists in Wizard101 . . . it's awesome . . . and since housing tours came along, I'm pretty sure you'd be able to find a house with a loot roll every day of the week, even if you didn't buy the house yourself (granted the owner didn't selfishly block it off or anything like that).
