Pike of the Forgotten Legion

You gain a +2 bonus to attack and damage rolls made with this magic weapon. This weapon has 6 charges and regains 1d4 + 2 expended charges daily at dusk. While holding this pike, you can expend 1 or more of its charges to cast one of the following spells from it (save DC 16): mirror image (1 charge), phantom steed (1 charge), speak with dead (1 charge), or spirit guardians (2 charges).

Spectral Warrior. Once on each of your turns when you hit a creature with this pike, you can choose to summon a spectral warrior from the weapon. Until the start of your next turn, that creature is haunted by the warrior. While haunted, a creature has disadvantage on weapon attacks against you. This property has no effect against undead creatures.

Haunting Phalanx. You can use an action while holding this pike to expend 3 of its charges and point it forward commandingly. Five spectral, pike-wielding warriors appear before you and march in a 25-foot-by-50-foot line in a direction you choose. Any creature within that line’s area must make a DC 16 Intelligence saving throw. On a failed save, a creature takes 3d10 necrotic damage and 3d10 psychic damage and is affected by the weapon’s spectral warrior property. On a success, the creature takes half as much damage and isn’t affected by the spectral warriors. Undead creatures automatically succeed on the saving throw.
