specific drop's card rate

[kilow]

Hi,

I didn't found / understand how specific drop's card rate works, aspecially if i need to set a value smaller than global value.
For example :
item_rate_card: 100000  //10%
item_rate_card_boss: 10000    // 1%
item_rate_card_mvp: 5000 // 0.50%
item_drop_card_min: 100
item_drop_card_max: 100000

For GTB, not 0.50 % but 0.25%

      - Item: Golden_Bug_Card
        Rate: 1 -- no change ( > 0.5% according to item_rate_card_mvp)

        Rate: 100 gives GTB card at 25%

but how to set a smaller value?

because writing this :

      - Item: Golden_Bug_Card
        Rate: 0.5 or 0,5 -- make error

 

I alsow tried to write
4128, 2500 in item_db.yml ( db/pre re and db/)
4128, 10 in item_db.yml ( db/pre re and db/) ( to test )

Thank you

@kilow if you want specific adjustment edit  https://github.com/rathena/rathena/blob/master/db/mob_item_ratio.txt

// Specific Item Drop Ratio Database
// Overrides for global item_rate* values from conf/battle/drops.conf
//
// Structure of Database:
// ItemID,Ratio{,MonsterID1,...,MonsterID10}
//
// Result:
// ItemID base drop rates defined in mob_db will not get multiplied
//  by global item_rate* values (aka drop rates) from
//  conf/battle/drops.conf. Instead Ratio will be used (100 = 1x).
// If no MonsterID is specified, all monsters will be affected,
//  otherwise only listed ones.
//
// Examples:
// 909,100 // Jellopies from monsters will drop with 1x drop rate regardless of global drop rate
// 909,1000 // Jellopies from monsters will drop with 10x drop rate regardless of global drop rate
// 909,100,1002 // Jellopies from Porings will drop with 1x drop rate. Other monsters that drop Jellopies are unaffected (use global drop rate).
//
// Notes:
// - By default you can list up to 10 MonsterIDs per ItemID.
//   It can be changed in src/map/mob.cpp by adjusting MAX_ITEMRATIO_MOBS.
// - Only ItemIDs up to MAX_ITEMDB are supported (default: 32768).
// - Does not override item_drop_*_min/max settings.
// - Does not affect card/item-granted drops. To adjust card/item-granted
//   drops, edit them in item_db.
// - Does affect MVP prizes and Treasure Boxes.
// - You can add only ONE line per ItemID. If you need various ratios
//   for different monsters, override drop rate with Ratio=100 and edit
//   base drop rates in mob_db.
// - This file is reloaded by @reloadmobdb.

//Add here
//Example
4128,500 // golden thief bug card drop at 5x drop rate or 0.05%

Rate 1 is smallest value that can be put on db.

Try set all drop rate in conf to normal value (100) and type

@mi 1086

In game, it will show exact drop rate 0.01% for sure. Then adjust drop rate at your wish and check with mi again.

i am not sure what you say exactly but i  would like all mvp to 0.5 ( so i set 5000 as i write in the first post ), except few mvp to 0.25 ( 2500). That is why i did like that, and adjust those few mvp after seting to 0.5 commons mvp.
If i understand you, i can only do that with adjustement mvp by mvp? ( make the card to 0.5% and 0.25 one by one?

ok
Thank you 

Ok, this works, thank you.

 i tried this line in a wrong file because it was written :

// - Does not affect card/item-granted drops. To adjust card/item-granted
//   drops, edit them in item_db.

English is not my native language so i believed that this comment said that for card it can't be possible to writte directly on the file.
