Clarification on bExpAddRace and bDropAddRace

[norightinfo]

Hi, I have clarifications regarding on bExpAddRace and bDropAddRace bonus, how does it work? does this adds on top of the current rate or does it overwrites the rate?

I have an item that adds 10% drop when killing monster (RC_ALL), Just to test this out, I set it to "bonus2 bDropAddRace,RC_ALL,1000;" which is 1000%. now assuming I have mob that drops an item(ex. Card) with 0.05 chance.

Doing the Math from what I understand:

0.05% (Card) + 1000% (bDropAddRace script) = 0.55% (expected result)

Result: When I test it out, it only displays 0.50% (I enabled announce on drop to check the changes)

Proof:
checking mobinfo - 

when it drops - 

-----

So this kind of make me wonder if does it overwrite, If I am wrong with my calculations can you enlighten me on how it really works?

Thank you.

I see, you mean it doesn't affect the announce message provided by the drops.conf ?

// Make broadcast ** Player1 won Pupa's Pupa Card (chance 0.01%) ***
// This can be set to any value between 0~10000.
// Note: It also announces STEAL skill usage with rare items
// 0 = don't show announces at all
// 1 = show announces for 0.01% drop chance items
// 333 = show announces for 3.33% or lower drop chance items
// 10000 = show announces for all items
rare_drop_announce: 333

Also, I further test with 2 additional items the same add bonus drop set to 1000% a total of 3000% (Upper, Middle and Lower)
This is the calculation:
0.03% (Card) + 3000% (bDropAddRace script) = 0.93%

Result: Drop announce with 0.90%, which removes the 0.03% decimal point, I guess it doesn't show some decimal point position or simply rounds it off (not sure though).

1000% = 10 times of your current item drop rate

so 0.05% * 10 = 0.50%

3000% = 30 times of your current item drop rate

so 0.03% * 30 = 0.90%
