I would like to suggest that the 3 City of Mercy orbs (Courtyard, Four Temples, and Sanctum) be able to be turned into one of the Cultists, and in return, you get one super orb that works on all of the wards. Something along the name of Orb of the City. This change would make a little bit more bank space, and would still require you to have all of the orbs at one point in time. Thanks for reading!
