Hold R2 + hit Circle, move ground targeting ring until it's red & on some mobs, hit X to launch attack (also like magitek). And then....nothing. It seemed like I could use the stun attack ok (when it wasn't on cooldown, obviously), but the Circle attack just was.not.firing. So unbelievably frustrating.
