Disabling Companions
I think it would be a good idea to have a "Disable Companion Effect" options so that you can still use the companion, but as an acessory rather than a bonus.What I mean by this is, you have a list of companions on a dog, but you only have 1 with an effect in-use. For example:
Enabled Companion
Short Faced Bear Cub
Disabled Companions
Dire Wolf Cub
Margay
Savage Werewolf
Large Stray Dog
So in that example, your 'Bear Cub has it's freezing affect... but the 'Wolf Cub, Margay, 'wolf, and 'Stray Dog are being used soley as accesories meaning that their effects do not occur on the dog.
