Overview

Byleth pulls out the Hero's Relic Failnaught to fire an arrow. He can charge it for more speed and damage, change directions while charging, and can charge-cancel with a shield until a certain duration. Charging at its maximum duration will fire a powerful arrow that has a similar animation and range to the staff item. A fully charged arrow can nearly break full shields. It must be charged a bit before it can be fired, similarly to how Bullet Climax cannot be shield-canceled instantaneously and must charge first. Byleth may occasionally say "Failnaught!" while using this move. The fully charged version pushes Byleth back and up when used in the air. Deals 12% when using a normal shot and 29% when fully charged.

Timing

Phase 1

Arrow	45-61
Interruptible	81
Animation length	107

Phase 2

Phase 2 spawns its arrow and it travels 300 units on the next frame. It will stop once it collides with something, preventing it from hitting multiple opponents like Light Arrow, unless they were hit right next to each other.
