In my opinion 6 is already a good number of slots! :) for vir you wont use branches or rings. So its just a lil hustle for micromanagement :) im always switching them out if i dont need em for the moment. Switch em in again in the moment i need and wait 20 secs use potions switch again... not that hard :D
Sharing potions with Yggdrasil and wedding rings. It could be nice to have item templates that could be saved and applied to towers. That would also be useful to simplify item swapping.
