Invested Champion

3rd-level evocation (ritual)

Casting Time: 1 action
Range: Touch
Components: V, S, M (a vial of holy water)
Duration: Concentration, up to 1 hour

You touch one creature and choose either to become its champion, or for it to become yours. If you choose a creature to become your champion, it fights on your behalf. While this spell is in effect, you can cast any spell with a range of touch on your champion as if the spell had a range of 60 feet. Your champion’s attacks are considered magical, and you can use a bonus action on your turn to encourage your champion, granting it advantage on its next attack roll.

If you become the champion of another creature, you gain advantage on all attack rolls against creatures that have attacked your charge within the last round. If you are wielding a shield, and a creature within 5 feet of you attacks your charge, you can use your reaction to impose disadvantage on the attack roll, as if you had the Protection fighting style. If you already have the Protection fighting style, then in addition to imposing disadvantage, you can also push an enemy 5 feet in any direction away from your charge when you take your reaction. You can use a bonus action on your turn to reroll the damage for any successful attack against a creature that is threatening your charge.

Whichever version of the spell is cast, if the distance between the champion and its designated ally increases to more than 60 feet, the spell ends.
