Arcane
Poison is pretty strong, but crap against undead who are immune. You are also not forced to get Ragnarok and it doesn't come with the anniversary edition. I don't have Ragnarok for example and have no intention of getting it because the reviews/opinions on it are super mixed. Ditto for Atlantis.
I will get them just for the Soulvizer mod which is a must have for me since it expands the game so much:

They are not that expensive either. 15 bucks base, add a discount and it barely hurts at all. The AE version has some really nice upgrades, my favorite being that you can increase the speed of the game, though I prefer "fast" over "very fast" because" very fast" feels... weird. By contrast "fast" hits the spot for me and alleviates one of my biggest gripe I had with the game well over a decade ago.
Also increases difficulty without the idiocy of XMAX.
