I guess something like this Warder, Level 100 (GD 1.2.1.6) - Grim Dawn Build Calculator (did SR 36 with no death not fast but quite safe - it is not an avenger warder though…)
Similar concept, but with no health regen [1.1.9.7] S&B Lightning Savagery Archon - SR 85 / Ravager of Minds / Avatar of Mogdrogen
