Create Deadly Potion

[BigBurrito]

I want the skill to instead of create one potion, creates two but get the items of one potion, which means 2x1. ex: If i collect enough items to make 100 EDPs, I will get 200 EDPs). I don't want this to be on an NPC for my VIP system reason.

I tried changing in  src/map/skill.c

 

case ASC_CDP:

if(sd) {

clif_skill_nodamage(src,bl,skill_id,skill_lv,1);

skill_produce_mix(sd, skill_id, ITEMID_POISON_BOTTLE, 0, 0, 0, 1, -1); //Produce a Poison Bottle.

}

break;

 

Changing the fourth value (1) into 2, but it did make 2 potion but it also got the items for 2 potions, I want it to make 2 potions and get only the items for one potion. Please Help, Thank you in advance!
