Request: Light of the Dawnstar should only resist hostile spells

It seems like the Light of the Dawnstar aura on Xoti's lantern resists ALL spells, even beneficial ones. I don't assume that this is intended behaviour. I was wondering if anyone was able to mod a quick fix, making it only resist hostile spells?

I also think the scaling is kind of bonkers. Since you'll want to stack religion on her for all of her other bonuses, you'll be getting an insane amount of spell resist with that. If reducing the scaling is possible, and not too difficult, that would be a welcome change as well.
