The Honed

From publisher blurb:

The Best. Period.

Every participant in The War has training, even if only a little. You are not trained, not proficient, not skilled. The art that has shaped your life since the day you were introduced to it has given you technique that makes a mockery of even your most learned peers. You are a hammer, a paintbrush, a river, and the world is a nail, a canvas, a shore. You are Honed.

The Honed is a pilot playbook for Beam Saber. They are unparalleled at one particular skill, but reaching that peak has left them completely incapable and uncomprehending of certain other actions. It's lonely at the top.
