After seeing the Torch God’s Favour item and how it works, I think the Guide to Critter Companionship should work similarly to it, as in it is a consumable that adds a toggle to the left of the inventory. This would be useful in both saving inventory space and summoning the Empress of Light easier, as otherwise the item would have to be removed from the inventory either from trashing or having to put it in a chest or a player vault.
