Destiny 2’s new Encore Exotic quest brings a handful of secret chests alongside its new auto rifle, Choir of One. These chests make the new weapon more powerful either by improving its intrinsic or granting you catalysts.
Choir of One’s unique effect causes it to use Special ammo, but it deals a good deal of damage with great ammo economy (at least until Bungie patches it). The weapon feels incredible to use, and even better if you can equip one of its three catalysts to make it even stronger.
