Death Rite Bird
"Death Rite Bird is a Field Boss in Elden Ring. These skeletal bird-like creatures are found throughout the lands between, usually at night. These are optional bosses as players are not required to defeat them in order to advance in Elden Ring, but they do provide useful items and Runes upon defeat. Unlike their weaker cousins the Deathbirds, they have a full set of wings and wield powerful ghostflame magic."
