One-handed Bow Mastery: Ignore Defense effect is not as expect

[mikeee]

Hi

The description of this attribute is “Ignores 5% of an enemy’s defense per attribute level when attacking with a [One-handed Bow]”

So I expect that when I attack an enemy with one-hand-bow and 5Lv attribute, the damage will be
"Skill Factor x Attack x log10(( Attack / Defense x 0.75 +1)0.X +1) + Additinoal damage."
Where "Defense x 0.75 " is the effect of this attribute.

But after some test, I found that the damage seems to be
"Skill Factor x Attack x log10(( Attack / Defense +1)0.X +1) + Additinoal damage + Defense x 0.25"
I only get Defense x 0.25 additional damage.

Could you help to check if this is a bug or normal setting?

Many thanks

Here I add some test result.
The experiment is done in Taiwan’s server.

Test monster is Rhodedoe with 896 DEF.

character physical attack: 1239~1239

calculated damage = 1239 x MIN(1,LOG10((1239/(896+1))^0.9+1))+896x0.25

= 680.853

test result: (match with calculation)

I think this formula is not the same with attribute description.
Since it doesn’t really ignore the DEF.

I also test Coursing of Hunter, which will reduce monster’s DEF by 7.5%
Target monster and phy attack is the same with above.
Pet attack is 4149.
Coursing LV5, enhance LV30: 296%

Calculated damage = 296% x (1239+4149x0.3) x MIN(1,LOG10(((1239+4149x0.3)/(896x0.925+1))^0.9+1)) = 4161.99
test result: (match with calculation)

So Coursing’s DEF reduce effect is as it’s description.
And this is what I expect that One-handed Bow Mastery attribute will do.

Please help to check this since this miss-match has significant impact on the damage of one-hand bow characters.
