i would like to know where you can find the rules about the addition of critical hit multiplier
exemple: i scrore a crital hit with a lance (crit x3) during a spirit charge that already triple my damage.... would id be (1d8 x3) x3 or it become 1d8x4 or x5...

you see what i mean so can someone explain me how it works

and an other question is if you got pounce so you can make like 2 or 3 attack in a charge and u got the feat headlong rush that double your damge on a charge... does it double all your 3 attack or only the first??

"D&D Math" works as follows: each "doubling" is an addition of the original damage. SO, 1d8 * 3 * 3 = 1d8 * 5

(Since "tripling" is, in this sense, adding twice your original damage)

What iconoplast says, but for clarification on the threat range (because that's also wonky): a doubling of 20 is 19-20. Therefore, a doubling of [x-20] is {[20 - (20 - x + 1) (2) -1] to 20.} For example, 18-20 is: [20 - (20 - 18 + 1)] = 3. 3 * 2 = 6. 6 - 1 = 5. 20 - 5 = 15. 15-20 is the result.

A bit complicated, yes, but it keeps things more balanced. Otherwise people could just stack multipliers and end up with x9 or more.

There is a much simpler way to say that...

If you crit on a natural 20 only, the threat range is one, as in, one number. On 19-20, it's 2, as in 2 numbers. Double 19-20 would be 17-20, a four number range.

As for iconoplast's math, I don't understand that explanation...

iconoplast's math works in a "step" system, as D&D does.

x1 is zero steps. x2 is one step. so on.

x3 is two steps. x3 + x3 = x5 because two steps up from x3 is x5.

So, literally, it's (m-1)+(n-1), where m is the first multiplier and n is the second?

thx guy for the reply but its not the threat range taht i got problem with .. maybe i wasent very clear sry..

if im a orc with the feats headlong rush that mean double damage on a charge.. if i use a falchion... the critique range is 18-20 x2...

so if i hit the guy and do a critique on my charque ... will it be 2d4 x3 or 2d4 x2 then i multiply by 2 the total for the feat.... (2d4x2) x2 ??? or what...

Multiplier stacking is additive, as iconoplast said and Arcane clarified. Bascially, subtract 1 from each multiplier, and add it all together, a la the formula that I posted to simplify it.

I know you weren't asking about it, but quite a few people have issues with the threat range. Inarai and iconoplast have the multiplier parts correct.

If you have a x2 multiplier plus another x2 multiplier, it's x3.

Close. It would be (m)+(n-1). Also, note that the "-1" applies to each multiplier after the first. So it would really be something more like:

(m)+(n1-1)+(n2-1)+...+(nk-1)

So a few examples:

[b]Original D&amp;D End<br /> Math double result[/b]<br /> ___________________________________________<br /> 2 x 2 2 + 1 x3<br /> 3 x 2 3 + 1 x4<br /> 3 x 3 3 + 2 x5<br /> 4 x 2 4 + 1 x5<br /> 4 x 3 4 + 2 x6<br /> 2 x 2 x 2 2 + 1 + 1 x4<br /> 3 x 3 x 3 3 + 2 + 2 x7
