Ok, I know this is a somewhat silly question, but I've been brushing up on my rules, and I noticed the take cover action. I always thought the if there was an object between yourself and the gun, you had cover, but this makes me doubt that, as well as ask a few more questions, which I figured I would post here.
1. Does the "Take Cover" action refer to just making yourself less shootable, and when you're behind something, you're just in cover for free?
2a. Do I use a simple action to look out of cover?
2b. If 2a is yes does that mean I cannot cast a spell from cover?
2c. If 2a is yes, does this mean I have to use a simple action to look out of cover, and another to fire, thus, leaving me out of cover?
