The Booster Laserer is a module of the Boosting locomotion; it provides a particular functionality for its parent Booster. If it is disabled or removed, then the relevant boosting functionality will behave as by default. Most modules can optionally affect change globally (for both hands' Boosters). Booster modules can also depend upon conditions specified by their dependencies settings.
The Laserer renders a laser in the boosting direction. This is useful for showing the player where they are aiming, which is especially helpful when Antidiminishing.
Different laser objects (example: different color lasers) can be setup to cycle via Booster Aesthetics Cycling.
