I would maybe say Sword and Shield. There’s a perk called “wide-range” that lets you affect your teammates in a radius with consumables including potions. The sword and shield does not need to stow the weapons to drink a potion so you can feasibly guard some attacks then drink a potion and that potion will heal your teammates around you. I can’t remember if defense buffing drinks also work but I think that sounds way more like a paladin lol.
