Zuri didn't know how to stop that huge wave of energy that was heading straight towards Zoey. It was just too fast for her to try to cancel it out, so instead of doing something that most likely wouldn't work out, she aims her staff straight at Boslan and charges up her spell before blasting it straight towards him, the shape of a spear and the speed of an arrow shot from a compound bow. The spell is intended to penetrate any magical shield, so the only way to stop it is to dodge it or cancelling it out with the same amount of force, which shouldn't be easy with the rate at which the spell was traveling at, however Boslan noticing that Zuri was charging up the spell earlier could be a possibility unless he was distracted or too occupied by something else.
