"Protego," James flicked the offensive spell aside with a shielding spell, his eyes now open and scanning the opponent for any surprises, anything she could throw at him. James never, ever, let his guard down with a wand in hand. In fact, he rarely let his guard down anyways. His cold, analyzing eyes, used to the blazing speed of battle, quickly spotted several environmental factors that he could use to his advantage.
He pointed his wand at Abbey, but as the incantation "Bombarda!" left the tip of his tongue, he angled the wand such that the spell would obliterate the ground in front of her. He did this four more times- once to the far right of her, once to the far left, and twice on either side of her. He flicked his wand quickly and stiffly, to conserve movement and energy, and so that he could easily angle his wand to block any incoming spell.
