Her own armour protects her from most of the impact, but it disorients her enough to keep her from firing off a blast. Plenty of time for you to close the distance and launch into a flying roundhouse kick.

The two of you hit the ground, sliding along the surface on your respective sides. Shooting back upright, you both charge at one another, launching into a flurry of strikes.
