Specifically, just a quick and dirty way to count average extra damage and whatnot. Only, I know nothing about math.

So. If a keen greataxe has a critical matrix of 19-20x3, about how much extra damage would that deal? I'm looking for a percentage here. Since I know nothing about math, I won't take any offense to people pointing out blatant errors in reasoning, etc.

Assumption: You hit on at least as many numbers as you threaten on.

Then your bonus damage from criticals is, on average:

x2 : 5% per threat range number.
x3: 10% per threat range number.
x4: 15% per threat range number.
x5: 20% per threat range number.
x6: 25% per threat range number.
x7: 30% per threat range number.

So a 19-20 x3 weapon is a x3 threat weapon which threatens on two numbers (19 and 20), so it averages 20% extra damage from criticals. That means that you can essentially figure nultiplying your initial average by 1.2 to figure your actual average damage.

Only multiply the damage that gets multiplied with crits, however. So if you do a d8 + 6 + a d6 of sneak attack, that's 10.5*1.2 + 3.5 damage, and not (10.5+3.5)*1.2.

If you'd like, I can show you the math proof, but it sounds like you don't want it.

The additional assumptions there are that you are attacking a creature which is susceptible to crits and has no chance of negating them (such as fortification armor).

Usually it's best to maintain your sanity and just work within these assumptions, but be aware that the actual average damage value of crits will be ever so slightly slightly lower than calculated.

And if we don't use the asumption that you hit on at least as many numbers as you threaten? Do you get a whole lot of different answers depending on what your to hit percentage is?

If you hit on less numbers than you threaten on, the number of numbers you threaten on is equal to the number of numbers you hit on.

So in the example of the 19-20 x3 weapon, if you only hit on a natural 20 - you are only doing 10% extra critical damage per hit. Again, assuming your opponent is not immune or resistant to criticals.

And assuming you can convert all threats to crits. Things like Power Crit do weird things to the numbers.
