Rose vs. Glynda

They've got smarts, they've got wands, but you expect me to believe that sparkly stuff's not magic?

Begin
While patrolling the halls of Beacon Academy, Glynda notices Rose approach the entrance of the building from outside the window. She exits the building to confront her.

''Glynda: What business do you have here? Identify yourself or I'll have to turn you away.''

Rose: I'm afraid that I simply cannot comply.

They both arm themselves.

HERE WE GOOOOOOOOOOOO!!!
Glynda launches several dust-powered explosions towards Rose, who keeps her distance and manages to dodge them. She then flies towards her opponent to close the distance, needles in hand. Glynda barely manages to parry Rose's strikes and jabs with a barrier once she's in melee range. Glynda punches Rose, sending her staggering back before blasting her with another dust explosion.

Rose manages to recover, only in time to see Glynda telekinetically tear a tree out of the ground and hurl it towards her. Rose blasts the tree to splinters with a beam from one of her needles. Glynda keeps up the assault, with everything from more trees, shrubbery, and chunks of the ground, most of which is parried, dodged, or outright blasted by Rose.

Eventually, Rose hides behind some rubble as Glynda lets up the assault to attempt to look for her. In this moment, Rose uses her needles to violently tear the chunk of ground that Glynda is standing on into the air before blasting it to pieces, sending Glynda through the air.

Rose flies at Glynda needles-first. Glynda attempts to intercept, but Rose's ability to fly grants her the advantage. She jabs and slashes Glynda with her needles, before smashing into her with a blast that knocks her away.

Glynda manages to move herself onto the ground to break her fall, and looks at her opponent to see a series of beams rising from the ground, one by one, each one getting closer and closer to her in a linear fashion. She tries to run to the side, but the path of beams follow her and eventually blasts her. Seeing this, Rose begins to walk away, before noticing the clouds above her getting stormy.

Glynda: You're not going anywhere.

The clouds begin raining shards of ice that Rose attempts to parry, but are far too numerous to stop. She is cut by many falling shards, before she is blasted from another dust explosion. Rose, bleeding, struggles to get up from the ground as the ice continues its assault. Rose flicks her needle upwards, destroying the storm cloud in a great explosion, before launching a massive spell beam at Glynda. Glynda puts up a barrier around herself, but it only holds for a few seconds before it shatters, and she is vaporized. Rose, still cut up and losing blood from the ice shards, kneels in exhaustion.
