The equation on the wiki is taking into account the probability of of all of the outcomes.Ī general understanding of it is: It works by doing one roll for double damage first, and if it fails, proceeding with the next. I was just simplifying it for conversation purposes. The equation you linked is what I was getting at. I think each are valued the same - neither stat is more significant Which has the same idea as the comment but with the order reversed This comment says DS happens then CS applied to what's left after DS happens I also do not know if PD2 has played with the mechanic and allows it to stack.Īre you saying that DS happens then CS happens without any calculation from DS? This having been said, this mechanism is difficult to truly test.

Whichever is higher takes precedent I believe. If a Barb were to use Gladiators Bane which gives +2 to crit, it doesn't get added to the crit from the Barbs General Mastery. For example, the barb gets crit chance from the General Mastery skill and the Amazon gets crit from its Crit skill. To my knowledge, depending on which class you are, crit chances do not stack from different class sources. It should be listed on a D2 wiki if you search deadly strike.

There's a calculation you could look up if you wanted to run the numbers yourself. While it doesn't simply stack the percentages together, you still have an overall higher chance to crit based on getting to roll 50%, twice. The value in having both is that you get two chances at doing double damage.

Roll 2 - Crit Percentage, if successful, then you do double damage, if the roll fails, you do normal damage and there are no more rolls.

If the roll fails then proceed to next step

Roll 1 - Deadly Strike Percentage, if successful, then you do double damage and ends the attack.

DS and Crit do the same thing but each chance rolls individually of each other, ie they do not 'stack'.
