Arcane Dominator

"A Magical Compound Bow once used by a charismatic dictator from long ago. They used this weapon to dominate the battlefield and blast waves of armies away, while using its magical properties to enhance their charisma and bring together the masses under a tight rule. No one knew where the weapon came from or how it was made, and its magical properties were never able to be recreated. One day the dictators entire nation vanished without a trace, all that was left was the bow, lodged into the ground on a barren field. No one was able to move or pick up the bow from the spot it lay. It stayed lodged there, as if waiting for the right person to one day find and wield it, and use its power to build a new empire with absolute authority.

On fail, the person/creature will be blasted back 25 ft. by a magical force, taking 3d6 bludgeoning damage and be paralyzed for 1 hour. If said person/creature attempts to pick the weapon up a third time, they must roll another charisma saving throw (DC: 20). On a fail, they will instead be teleported to the Astral Plane for 24 hours, where if they survive, they will be teleported back to their original spot. This curse is only lifted as long as this weapon and the person/creature attuned to it are on the same plane of existence.

Each spell will cost a different number of charges based on the level of the spell. To use a spell, state which spell you intend to imbue into the bow, then use your main action to make a ranged attack. If the attack hits, the spell you choose will act as written. Spells that are activated as a reaction or bonus action can still be done so without making an attack, but will still use the required number of charges. Charm and Buff spells can be done without doing damage if called before hand. Ritual casting is not possible through the bow.

-Warlord's Ethereal Call: You can use available charges on the bow to summon apparitions of warriors from the Ethereal plane (or any plane of existence the DM chooses).
