So my buddy got nailed by a walrus, and it hit him for HHP damage of 55% of his total health bar in a single hit. I'm just assuming the animals have the same "Only deals 100% of your MHP in a single hit". Does anyone know the grievous damage values for various weapons/animals so I can determine what the "assuming KO to hearthfire works, I'm safe from permadeath if I have at least X% HHP of my MHP"
After thinking about it, with that restriction "safe" means double the max grievous % in a fight. If the walrus actually did get his damage capped and naturally deals 55% grievous, it's always possible a walrus can insta kill you from max HHP to nothing. He'd have to almost knock you down, then deal all of your MHP in one hit.
Depending what grievous is for the various pvp weapons, I can see a way people can cheese this to ensure fairly regular instakills. But at the same time I'm not sure what the weapon %s are.
