pretty non-passive [1.1.3.1] Sir Dredeon, Bloody Oppressor - Melee DW/Player scaling pets Blood Knight Vitality Oppressor (no greens, Gladiator, SR 75)
I think the “best” option would be to go with player scaling pets.
And this [1.1.3.0] [Caster] Vitality Oppressor (sr/sr+) - feat. fake pets
might be hard to do some kind of “budget” version of them as they require pretty much all that gear
