Maltel is a holy spear.
Maltel was a gift given to Jeanne d'Arc from Michael, after she was chosen as a vessel for the gods. Armed with this spear, Jeanne was able to utilize Michael's power and use to defeat and kill formidable opponents, such as the demons Pazuzu and Azazel.
The Maltel emits a bright golden light when used, both when firing projectiles and during charge attacks, with the apparition of Michael appearing every time. Jeanne is also able to recall Maltel to her hand.
