Formula for single hit damage
#1
So the other night in a SM Library run, I encouraged Alram's 36 rogue to roll on the Hypnotic Blade. He was reluctant, as the int bonus does him no good, and the fast speed makes it a poor choice in the main hand, particularly for ambush.

So discussion afterward (he did roll at my urging, luckily no one else wanted it) made me doubt whether I was correct. His current main hand dagger is Broad-Bladed Knife, which, while the DPS is poor, has a very slow 2.0 attack speed. I had to concede that I didn't run the attack power numbers to see if I was correct in assuming that the huge DPS margin between the two was actually enough to make it better in the context of a single hit. I'd always done such comparisons by simply measuring the average of min and max.

So, I thought about it and came up with this. I'd like to have people correct me if I'm wrong. There are two parts to single hit damage as I understand it, the weapon portion, and the attack power portion. The attack power portion will scale up depending on the weapon speed.

Formula for single hit damage:


(WpMin + WpMax)/2 + AtkPwr*WpSpd/14


While the original question dealt solely in terms of ambush, I believe ambush is a % multiplier and an additional flat add on top of this, so just this formula should be sufficient to answer the question.

So, our two weapons:

Hypnotic Blade: 26-49, 1.4 WpSpd
Broad-Bladed Knife: 23-44, 2.0 WpSpd

Setting these two weapons equal, I want to see how much attack power you would need before the Hypnotic Blade lost in terms of single hit damage comparatively. This comparison is easy as neither weapon has a mod that changes attack power:


(26+49)/2 + AtkPwr*1.4/14 = (23+44)/2 + AtkPwr*2.0/14


Solving for AtkPwr yields 1.33. This makes sense because the weapon only portion is very near, and the attack power portion scales up quite a bit quicker on the broad-bladed knife.

Does all this look correct?

It's a pretty good bet that a level 36 rogue has more than 1.33 AtkPwr :blink: so it appears that I was wrong to encourage him to declare need. So, I'm sorry for pushing you to take this Alram -- good news is it was greed for everyone else.
