Santana, walked into the arena, and looked at the fog, it was peaceful, she doubted she'd have much peace in the next 10 minutes with this duel. She'd been sent a mask, showing half of her identity but she declined the offer, she didn't have to hide her identity, she didn't have anything to hide in general.
She saw a person at the end of the field, opposite from her wearing her mask, her brain racked for ideas, of people who might be hiding themselves, Milo, James, Jack? She had no idea. She saw the owner enter the middle, and say, 'Let's begin" she drew her wand to make the first, move but she could tell the other girl beat her to it as a spell, cam at her fast. It hit her in the chest, and sent her flipping and spiralling in the air, this was not fair.
She had broken her wrist from that fall, easily not she'd just have to do the same. This wasn't going to hurt the girl, but punish her, she pointed the wand at her, and whispered, "Furnunculus" and then yelled, "Obliviate," but she though because she was so far away, the second spell would miss the target only time would tell. She was about to cast again, but she was fair, she drew her wand to her chest, and waited to block the next attack.
