try it
btw with this script you can gain 2 cards at once (normal drop+by script)
I suggest to implement theses commands on your server (rathena only, search the trac)
*addmonsterdrop <monster id>,<item id>,<rate>;
*addmonsterdrop "<monster name>",<item id>,<rate>;
*delmonsterdrop <monster id>,<item id>;
*delmonsterdrop "<monster name>",<item id>;
These commands will temporarily add or delete a monster drop, which will be reset
when the mob database reloads or the server shuts down. They return 1 upon success.
If the monster already drops the specified item, its drop rate will be updated with
the given rate (100 = 1%).
Examples:
// Makes Owl Baron drop Honey at an 80% rate.
addmonsterdrop 1295,518,8000;
// Deletes Executioner's Mitten from Rybio.
delmonsterdrop 1201,7017;
in order to prevent that from happening, you must remove the id card number from the mob_db of that mvp.
