Best Skill for Auto-Buff So as you may already know, Beefy's Kitchen lets you craft a lot of things like pet skills that are permanent when you apply them. Since I already have a pet, I decided to make skills that I feel like are useful and soon I'll probably make the auto buff one.The only problem is that I don't feel like Mercedes has that one essential skill that needs to be active 24/7 which makes me question if Auto Buff is even worth the 400 coins. Anyways my obvious question is which buff would be most beneficial to always have turned on?
