Hitbox visualization showing Byleth's neutral aerial, when landing.

Overview

Spins Failnaught around himself, hitting multiple times. Byleth's fastest aerial attack. It is useful for edgeguarding and approaching, has some combo potential, and it also possesses a landing hitbox, making it a useful multi-purpose aerial attack. Byleth may occasionally say "Failnaught!" while using this move. At its highest, it does 10.5% damage overall.

Nairquake Loops

The Nairquake Loop is an advanced combo that involves the use of repeated neutral aerials, with a fast fall during each one to get the landing hit. While this may not kill on its own, it can potentially deal a lot of damage and lead into other combos.

The exact number of repetitions in each loop varies depending on the character. A list of how many repetitions can be done on each character can be found here.
