She had missed, the glengal shifting so her strike missed the space between plates. However, her soulsense, spread so she could see the entire fight, allowed her to witness Kaeni's attack and learn how to defeat the glengal. "Mercury!" she yelled, "Get it from above!"
At the noise, the glengal's tail arced toward her, barb aimed straight for her chest. She stumbled backwards a few steps, then tripped on a rock and fell backwards, her head hitting the ground not quite hard enough to daze her. I should have practiced my falls more! The glengal's aim shifted as she moved, and she rolled to the side as it was about to hit her.
It missed her chest, but hit her arm. Her sword arm. She cried out as fire shot through her arm, down to her fingertips and up into her chest.
