Or maybe upgrades for the medallion, to carry more spirits with you.
I don't know, maybe you can carry 6 at a time, but only 3 are actives (To battle, and for their abilities).
On one hand, I feel three is a good balance.
On the other, it could prevent back and forth to a spirit tree to change your team.
Also, bonus point : the ability to, when you charm a spirit, to add it to your party when your party is full. Then, you can choose which spirit of your current team to send to the tree.

This would be amazing, especially since the dev team wants to add more spirits in the future 😄 6 slots would give people enough wiggle room for team building and encourage more mons to raise 🙂

An upgrade to allow at least a 4th in battle and and 2 as follows would be nice
