Some mod in BWS is giving lots of NPCs mirrors

I'm not sure what mod does this, but in my megamod install there's some component that gives many NPCs an item called DW#HASPT and puts it on their off-hand slot. It's a mirror that gives them the chance to reflect gaze attacks.

It's annoying because it's removing the off-hand weapon or shield of many NPCs, and it also gives them a physical mirror visual effect on them constantly which I find a bit off-putting. I can't figure out where this component comes from.

For those that use this tool, do you know where this could come from, or how I can find this out?
