Upgrade for any unit: Attach Blossfechten vertically or horizontally. When the attached unit is targeted:

You may change the rotation of Blossfechten once during your own turn.

Blossfechten, or “bare fighting,” referred to unarmored combat with swords or other weapons. It was a key aspect of German martial arts, focusing on skill, speed, and technique rather than brute force.
