run 0 fhr so when you tele thru Urdar packs you feel your adrenaline spike as they smack you around
outside of these guys, their tree/snowman clones, and lister, you won't get put into fhr animation unless something breaks your es, assuming you have enough actual damage nullification. Which isn't always enough, either. Aim for whatever BP you can reach without any serious sacrifices. Anywhere from 30-60 is fine. 20 and less is really pushing it, even if fhr only comes into play for edge cases.
This is the information I was looking for! Really appreciate you taking the time to fill me in on this.
