Packet editor question

how do i edit pockets like for example:

am doing a quest and i need 10 monsters and when i kill that monster there is a drop that says what you just collected

how do i edit that i can only edit it when its a find quest but i cant edit the packet when its on a monster quest can you help me out here D:

I don't understand your question, but packets don't create the item or make it drop. They simply auto pick up the item for you
