if you want you can take theorycraft inspiration from this one Oppressor, Level 100 (GD 1.1.9.6) - Grim Dawn Build Calculator
keeping in mind some of the build considerations was made because of the specific class, like the existing necro RR and passives it had, [1.1.9.5]: The Oppressor: 4:20 Crucible, Shard 90, Celestials, the ultimate vitality EoR Oppressor by mad_lee , so need to remember not everything will apply to a paladin,
ex necro gets X RR in class, build uses different amulet. Your paladin doesn’t get same RR so you using a RR amulet might be smart
but like, overall dmg bonuses, RR, conversion amounts, defenses, speed etc
