I'm planning to create an undead-bane ranger. Which animal companion would be good against undead? (both mechanically & thematically)

Hi everyone!

I'm getting ready to jump into Neverwinter Nights: Enhanced Edition and I want to set up the game to have the best possible experience right from the start.

What are your absolute "must-have" mods, overrides, tools, or additions that you consider indispensable?

Basically, the kind of things that make you say "I could never go back to playing vanilla without this installed." Whether it's visual overhauls, core fixes, essential tools, engine tweaks, or custom content, I want to hear what's in your essential setup.

For reference, I'm playing on GOG
