Passive Perception? Other Passive skills? (Also, nat 1 and nat 20 on skill rolls?)
I'm just reading through the 5.5e core rulebooks. I came across passive perception in the Monster Manual, and looked it up in the Player's Handbook.
Is it basically "take 10," but automatic?
Also, are there other skills that get the same treatment? Like, for instance, History? "You glance at the painting and it sparks a memory" type of stuff?
I've been watching a lot of comedy sketches ("group at the table playing D&D, here's 3 minutes where something funny happened"). I'm seeing a lot of nat 1 and nat 20 references. I thought that those only mattered during attack rolls? Do they apply to saving throws and skill checks, too?
