I still think I like Saeryn's Better than Denny's, Last time I played vs Denny, I was able to use incite and boosts etc to counter the effects of the feat. Saeryns' says you straight up can't do something, no matter what.
Well, her feat shouldn't be used to bring down the strength and mat/rat. That is just a bonus. Bringing the defense/arm down is crazy to just anhilate things. but the speed is the money maker. her spell list aside, with the right list with lots of stealth to avoid the shooting, you are golden. Then add her spell list to make you platinum.
