The Vow should have the Memory of Timur perk from D1 Rise of iron.
Memory of Timur: Melee attacks on minor minions of the Darkness have the chance to temporarily turn the target against its allies.
But in the Vow it should be non lethal hits.

Since the Vow is a bow belongs to Crimson event, i would rather suggest a perk such as Vow of Love : When you get close to a team member carrying also the Vow, you will get an stronger shield colored in Crimson.
