They have no bounty attached to them if that's what you're asking. If you're asking if they kill CS do you get the gold for it then the answer is yes.
Yeah the bounty.
May I ask what to build late game? I usually get boots + 3, HG and then Sheen.
What is this? I don't even... No that's a bad idea. Go like this are you winning lane? Buy Abyssal. Are you losing lane for some unknown reason? Buy a Frozen Heart against AD, Abyssal against AP. Congratulations the game is now over.
