Ok, so with things like Force Push, Lightning ect...do you still follow all the normal targeting rules as if you were making a normal ranged attack? Or being range sight can they target anyone they can draw los to. Same question for stuff that have range 6 like grenades, they have to target the closet without cover?

If it says "target" it follows standard targetting rules, unless otherwise stated. Sight is a range.

And it appears you have it slightly wrong. You can't target someone in cover UNLESS they are the closest enemy. It is a small distinction that can trip people up.

Ya thats what I meant, I just worded it wrong, I appreciate the quick answer
