Have gotten through most of the Majesty Original spells and have been fiddling with making proper Hero Support functions to allow them to work better as a team. Also fixed some bugs inherent in the base game such as multiple Charm stacks on a single target. All that's left is the Priestess and Generic Spells to port over.
