Titans Quest Anniversary Edition

Just learnes that Steam has this and bought it cause ling ago my physical copy of TQ was lost. Boy I forgot how much I lives this game but a wuestion for those in the know. Back in the day I used a Conqueror build and it was pretty easy this go round I’m going Brigand (rogue/hunter) cause I never used bows. My question is most faqs I see on them say that poison is useless in epic and legendary on undead and skeltons however I have noticed that at least in normal skeletons take poison damage. Is his simething that changed with the anniversary edition as most of the faqs are 8+ years old. Just want a good build that can destroy legendary secret area like my old conqueror.

Sorry for bring up a non Grim Dawn question but figures this was a good place to ask due to it being what Grim Dawn spawned from.
