Susan grinned as Seamus muttered darkly about the birds. Battle Magic 101 was always to try and throw something weird and distracting at an opponent. Indeed, Susan's crowning glory was when she'd transfigured a dozen chairs into a herd of enraged sheep and unleashed them on her confused, then terrified opponent. Still, she decided that Seamus wouldn't be interested in that.
As it was, she nearly missed the incarcerous spell he hurled at her, purely because it was unexpected - thus proving her point. It shattered against her shield, but still managed to smack her in the cheek, drawing blood. Right, she thought, her eyes hardening and a battle fog taking over her brain. Jumping to one side, she fired a moderately powerful Confringo at her friend, before feinting left and firing a leg-locking curse at him. She then jumped back like a cat, and threw up the strongest shield she knew.
