I was resetting enhancements on a dwarf FvS after hitting level 20 to switch from leveling to end game and know how much poison is involved and thinking it might be worth it now to start taking enhancements in the Dwarven Poison Resistance line. I'm just getting to hitting this new content so inexperienced first hand.

What are people experiencing? Could this be the new Dwarven Spell Defense to take in the case when saves at level 21-25 might just need to be sick high anyway?
