I've been enamored with the Dhampir Class, and Ideally, I would use it with Matt Mercer's Blood Cleric class. But in the event that I can't, (more than likely my DM would not allow us to use UA with HB) I'm trying to find classes that allow me to distribute my health amongst allies and maximize my bites effectively.

• I'm considering Eldritch Knight and Bladesinger for access to Vampiric touch and while maximizing the number of extra attacks one can replace with bites.
• I'm also considering death cleric, for the access to vampiric touch and maximizing all necrotic damage.
• I'm considering Paladin Classes, especially Crown, because I can substitute damage to party member's hit points with my own large replenishing constitution, and a few extra hit points and spells.

Which do you guys think is the best class combination to achieve this goal, converting hp to healing, a sort of savage bloody healer, is there something I haven't considered?
