Trivia
- Compared toAreadbhar andAymr, the main relic weapons ofDimitri andEdelgard, respectively, Failnaught has the notable distinction of being the only one of the lords' main relic weapon that can be obtained and used outside of the main wielder's route. In this case, Failnaught,Claude's main relic weapon, can be used outside of Verdant Wind (Claude's route) in Azure Moon (Dimitri's route).
- Claude'sartwork from early press kits forWarriors: Three Hopes mistakenly features Failnaught with theCrest Stone ofGautier instead of the Crest Stone ofRiegan. This was fixed inthe version posted on the official JapaneseFire Emblem Warriors Twitter account.
