It's "plays"

And yes, thegrave, you are absolutely right. But remember that having good +skills is not too useful other than when you're casting venom. Otherwise, you should use CtA. But if you REALLY want to use +skills weapons on your switch, remember to use the Battle command on the CtA FIRST, to get that 1 point difference with your venom, which can be around 500+ poison damage.
