You use your magic to flip the table over with your magic really quick, giving Red some cover.
You then bring your rifle up, imaging the mare was a simple dummy at the range, and fire. The shot hits and the suit does little to protect her, sending the bullet through her kidneys and straight out the other side.
The mare cries out in pain, but manages to fire. Her shotgun was pointing up so the bullets hit the roof instead. It also fell from her grip, sending the shotgun into her face and knocking her out.
One of the last two get a pistol out and tries to fire, only for Red to shoot him dead on the ground. The last one gets up and starts making a break for it.
What do you do?
