The Blessed Lance (聖なる槍 Seinaru yari, lit. Holy Spear) is a Lance that debuts in Fire Emblem Gaiden. As its name suggests, this lance is imbued with the divine property of inflicting effective damage against monsters. In addition to this, the lance automatically restores a small amount of HP to its wielder at the start of every Player Phase.
In Fire Emblem Warriors, this is also the Signature Weapon of Azura via DLC. It retains its effectiveness against monsters, however it doesn't restore the player's HP.
