I had an idea for a pet that has a spell deck of its own and its own pip bar. Then you get to customize his deck and he will count as a fifth member of the team. Most of them could be crowns but i would really like it if non-crown users could get weaker ones witha slightly smaller deck. I also had an idea for A miniature wizard that you could equip items to or a display model house item to show off your extra armor.
