The maximum damage of Combust, Dismember and Fragmentation shot is increased by 20% weapon damage per rank, but enemies that move will only take 1.5X increased damage.
Where values less than 100% ability damage are boosted to the minimum of 100%.
$ random(1,100) $ represents a random number chosen in the range $ [1,100] $.
From this, we can calculate the chance for the ability to perform its minimum possible damage:
$ \frac{100}{188} \approx 53.19% $
The damage multiplier from lunging is added to the maximum ability damage and has no effect on the minimum hit. As such, for rank $ R $ lunging, damage follows:
This formula also affects the chance to hit minimum damage:
$ \frac{100}{188+20R} $
Knowing this, we can also calculate the average hit $ A $:
$ A = 100P + Q(144 + 10R) $
Where
$ P $ is the chance to hit minimum damage; $ P = \frac{100}{188+20R} $
$ Q $ is the chance to not hit minimum damage; $ Q = 1-P $
The movement multiplier is added after all other calculations are done, so the average hit is simply multiplied by that number for analysis:
$ A_{moving} = \begin{cases} 2.0 \times A & \text{if no Lunging} \\ 1.5 \times A & \text{if Lunging} \\ \end{cases} $
The movement multiplier is only present on Combust and Fragmentation Shot; Dismember does not deal any increased damage for a moving target, with or without this perk.
