Except that this damage get's a bit weird during a back-stab or riposte. A backstab under these conditions does 2200 damage, and a riposte does 3700. I'm not sure -why- this happens though, and I'd love it if people could find out why. The hornet ring, as expected, boosts those numbers to 3300 and 5050, but none the less, the damage increase is exponential here, and I'm not sure of why. I've got a theory though.
Obviously it's multiplying the AR by 18 in this equation, I reached this answer by testing a fist weapon that had 360 AR. vs the first mobs outside firelink, the damage is exactly the same inbetween the two weapons, leading me to my conclusion on the multiplier. My assumption is that a backstab and Riposte use the same multiplier for... different results though. If a backstab and riposte add the bonus damage to your AR, that would do some very funny things to the dragon fist, and might explain the disproportinate damage. Otherwise, do we assume the Dragon Hand has a 200 or 300 critical bonus? What is your thoughts on this? I'm very confused...
