For some reason whenever I play the OG NWN2 Campaign at some point between the swamp ruins and Your step foster father sending you to Neverwinter, I get 10 additional health added to my max. It is consistent so it is either an unavoidable bug or canon for the story. I looked in to the common glitches and this does not match any of the max health glitch scenarios. Does anyone know what is going on?

In the event that it matters, my char is a human rogue/fighter geared to become a Blackguard.

nvm I figured it out after all these years.

Well for anyone else wondering, it is the shard you pick up in the swamp ruins.

Yes, it was. I just ever accepted it as a quest item that I couldn't equip. So I just kept it in inventory and only paid attention where it was in the storyline. Didn't even know that things not equipped could affect your stats.
