Sorcery employed by the servants of Death.

It involves striking the ground with the staff, causing an explosion of ghostflame that engulfs the surrounding area.

In the era without the Erdtree, death was engulfed in ghostflame, a fire guarded by the Deathbirds.

To acquire this sorcery, travel to the end of the river southeast of the Abandoned House.

Defeat the BOSS Death Ritual Bird that appears in this location during the night to obtain this formidable magic.
