Discrepancy on Damage page on wiki
Posted: Mon Mar 26, 2018 5:46 pm
When looking at the table for Damage, Flat Resistance, Modified damage (with 0% resistance) I've noticed it doesn't line up with the formula when modified damage less than 1.
For example, The table says when raw damage is 5 and Flat Resistance is 5 the modified damage is 1/2 (.5). However, when inserting those values into the following formula:
M=1/(1-(D-R))=1/(1+R-D)
M = 1/(1-(5-5)) = 1/(1+5-5) = 1/1 = 1
The result is 1 not .5
I would think the table is correct for all the examples, not the formula, since it would make sense in the example of:
raw damage is 5 and Flat Resistance is 4 the modified damage is 1. As a result, the damage should decrease not stay the same if flat resistance is 5. But this needs verified.
I think the formula should be:
M=1/(2-(D-R))=1/(2+R-D)
Also, this means that the formula that incorporates the percentile resistance (when modified damage less than 1) needs modified if the assumption above is correct:
F = (1 - P) / (1 + R - D)
