Einherjars (死せる勇者の魂) are magic constructs that can be summoned either through a skill or Tier Magic originating from YGGDRASIL.
Einherjars are golem-like constructs created from magic. Once a magic caster initiates the spell, a ball of white light coalesce in front of the magic caster, which slowly shapes itself into a humanoid form until fully resolving itself into the shape of a person.
Einherjars are considered physical bleached-white replicas of their summoners.
Einherjars, though a cosmetic reflection of their creators lacks spellcasting abilities and several skills. While possessing no magic items, they are able to mimic their summoner's overall appearance of weapons, armor, etc. The stats of these beings were otherwise the same as the user who summoned it. As golem-like constructs, they nearly had identical resistances and immunities like the undead.
- Shalltear Bloodfallen is able to summon an Einherjar and use it as her trump card as shown during her battle with Ainz Ooal Gown in Light Novel Volume 3.
- In Norse mythology, Einherjars are warriors who have died in battle and are brought to Valhalla by valkyries.
