Has anyone tried to get the Armor rating of an NPC? OBSE doesn't have a function that can get it that I can find, although FO3 has a vanilla AV function that returns it. There are so many variables involved and in some cases if a piece of armor the NPC is wearing isn't supported by the OBSE function GetEquippedObject (like the Daedric Helm and Elven Helm which use hair and head slots) then getting the current health is not possible, which would throw off the calculation.

I'm just curious as someone asked me about it, and before I start writing a script in vein I was wondering if anyone else had tried it yet.

Tried Getav defendbonus

It won't get the rating of individual pieces, and might be adjusted by the skill of the actor, but it's about as close as you're going to get short of detecting each piece of armor individually and doing all the math.

Nice, thanks. Didn't even think to look at non OBSE functions for some reason.
