[BUG] Major wounds and damage calculator — "The Mystery of 1"

The Mystery of 1

Hi there, creating this issue by the Nick Coffin, PI#8616's request.

Originally I've noticed some fudging in Damage Calculator's work — DC(Damage Calculator) made you roll twice for major wound to an eye, both without any modifiers. While in reality victim must take a single roll with -10 for the eye injury. By exploring more, I've noticed a pattern. Here's what I've found out: 1) I've experienced the same issue with Eye, Face and Vitals hit locations. 2) Under certain circumstances, DC calculated Major Wound modifiers Properly. 3) Originally I was using [1d imp] OTF and the issue persisted IF I was applying 1 imp damage. But then, I've tried the same thing with [2d imp] OTF and the issue mostly persisted if I rolled 1 on both dice, giving a net of 2 imp damage. So my guess is that the cause lies near the number 1 — if the result is the lowest of all possible, then it happens. At least I know that you may try to simulate the issue with the result of 1 imp on [1d imp] OTF. 4) In my case, the issue persisted only if all the dice I've rolled gave the lowest possible result. But interesting enough, I was actually able to simulate the issue with the result 2 on the die on [1d-1 imp]this formula. After calculations I've got only 1 damage to apply and the issue took it's place.


Tests

So here is some tests. What I did is I threw a bunch of [1d imp] and [2d imp] OTF's until I've got the needed result — a total of 1 for [1d imp] and a total of 2 [2d imp]. Damage was dealt to the Eye, Face and Vitals hit locations and the DR was 0 in all cases, thus everything had penetrated DR. The results for major as follows:

1 die

  1. Eye → No modifier, two rolls instead of one.
  2. Face → No modifier, one roll.
  3. Vitals → No modifier, one roll.

2 dice

  1. Eye → Modifier -10 for both rolls, two rolls instead of one.
  2. Face → No modifier, one roll.
  3. Vitals → No modifier, one roll.

1 die of imp damage, 1 imp damage from this die
