Spirit-soldier
From MUME
Spirit-soldiers are aggressive level ~14 mobiles found in Old Fornost. They are incorporeal. They load with a weapon, and will also pick up items from ground.
An ancient spirit, dressed in the arms of a soldier, challenges you. >examine spirit Standing alert here, this soldier raises his weapon against you. The armour he wears is quite visible, however, the skin underneath is nearly transparent. His ancient and grizzled face seems full of unquenchable hunger...hunger for death, hunger for life, hunger for vengeance.
