[How to enable an item db like this?]

I look up a JRO weapon that discribe the effect like this:  Deal extra damage to the monsters in the Biolab and nightmare Biolab based on the refine, I try to use the "bonus2 bAddDamageClass,mid,x;"，found out it has a mount limit, can only use to 10 monsters. So how can I enable the actual effect like the weapon discribe ?

[How to reduce bonus time or remove a certain bonus from a player?]

If I use the "bonus_script" to add multiple bonuses to a player, how can I reduce just one bonus' duration or remove a certain bonus instead of using the "bonus_script_clear" to clear all of the bonuses?

1.) Store string variable of all card bonus.

2.) Players bring card to NPC.

3.) Store int for index of card and Use bonus_script with 999999999 timer for each card bonus when player success trade / login.

 

It's not the best idea but I confirmed this can be use.

Thanks, I will try, but I'm not learning the script enough, so it  may not work eventually, but thanks for the idea !

[Want a card consume NPC that gives the player permanent bonus!]

1、A NPC that player can give some cards to

2、After recieving a card, the NPC will give the player bonus like the player actually equiped the card, or gives player some bonus of the card.

3、The NPC can check wether the card was given by the player or not, and the same card cannot be given again.

Recently I used a shop script that contains a lot of invalid items, items that exist in the iteminfo.lub but donn't exist in item_db.txt. How can I  use a script to check and delete invalid item in this shop automatically?
