Final Wish

The wielder unleashes their hearts wish that bonded them to the shards. A beam of shimmering light shimmering forms around weapon's form and the user gets ready to release. With every wish made, the projectile shimmers until it's swirling with prismatic light.

The wielder will hold their attack until the next round, upgrading the shooting star attack to the Final Wish Ability. The target must make a Charisma saving throw equal to the caster's Charisma Ability Score. On a hit, the target takes 4d10 radiant damage plus 1d10 for every level equal to the max spell level of the wielder. Once fired, this ability cannot be used again until after a long rest. If attacked, the wielder must make a constitution saving throw. This ability must be used as either its Alpha or Omega form. The wielder must also re-bond with the shards, using a new wish.

Alpha: The user can choose to add their remaining health points to the damage. Doing this will cause the user to fall unconscious and will begin death saves on their next turn.

Omega: The user can choose to add their remaining health points to the damage. In addition, the user can add 1/2 of their maximum health point total to the damage total. Doing this will cause the user to fall unconscious and forego death saves. Only the spells Resurrection, True Resurrection and Wish can bring the caster back.

Bonus Damage: After the caster's initial turn, each player that comes after can choose to forgo an action or bonus action to add additional damage to the maximum total damage. 1 Action = 1d10, 1 Bonus Action = 1d8. For every player that adds damage, the Charisma Save Score goes up by 1. (e.g. base cha is 20, 3 players add damage, new score is 23 to beat)
