You can’t just equip any weapon!
The Duet Night Abyss Consonance Weapon feature only works for those who summon weapons with at least one of their skills. To see which weapons we recommend in Duet Night Abyss, take a look at our Duet Night Abyss Weapons Tier List.
Consonance weapons and weapon proficiency are similar in some ways, but different in others.
In Duet Night Abyss, Consonance weapons are those that are tied to a specific skill of a playable character. For instance, if they have a skill or an ultimate skill that requires them to summon a weapon, then that weapon is considered a Consonance weapon. This is not solely a feature for 5-star characters, though, as there are also 4-star characters who utilise them, too.
Weapon Proficiency, however, is something that all characters have. The weapons they wield in battle depend on their overall Weapon Proficiency. Each character uses two weapons, with one being a melee weapon and the other being for ranged combat.
