Claymore Greatsword mod - requesting help with a few things

[TheRizzler1]

Seems I've been posting in Mod Talk rather than this more relevant subforum, woops! The title no longer really applied anyway.

I've been working on a Claymore Greatsword weapon mod and it's nearly done, I just need help with a few more things;

 

1) how can I increase the health/damage resistance of an NPC without having to add more amour? You need to kill a lightly-armored NPC to get the sword; here's his stats page. The HeavyArmour value didn't seem to do anything

 

 

2) How can I make my workshop/special furniture glow at night/in the rain like other ones in the world do? Pictured left; an existing cooking pot, right; my cooking pot

 

 

Thanks for the help.
