There's no Warlock "fix" that you approve of, Bel? (they're homebrew - basically they tend to give some more Invocations)
I'm prioritizing the Rose Petal game, but for this one that also looks like a lot of fun I was thinking a necromancer with a complete lack of morals (so not a fan of evil/rampage, but just unable to distinguish a good from a bad act...), mechanically a (ranged) Warlock or Cleric/Warlock/Eldritch Disciple.
