Ashen remains in which spirits yet dwell are used to summon the spirits of five mausoleum soldiers.

These spirits represent five headless soldiers who confound foes by disappearing and reappearing at will.

The mausoleum is where the bodies of soulless demigods are lain to rest, and these soldiers followed their masters into Death by severing their own heads from their bodies.

The ashes are located at the bottom of the deep root layer as shown in the image below.

The ashes can be found next to a tree stump at the edge of the map.
