Bring Down Those Shields

Look at the button on the side of the controller here. I bet if you got close enough to one of those scourging crystals, you could use the controller to bring its shield down. Then it would simply be a matter of destroying the thing before its shield goes back up.$B$BWhat do you say, $N? You up for it? I can guarantee a nice reward for you if you can bring down those shields and destroy the crystals.$B$BIt's the least we can do to keep the Scourge from making more of their own kind.
