I have a question.i set some custom drop at few monsters,but when i kill a monster,i dont get all drop.i get only 1 of them.can someone tell me how to get all items in a drop,no 1 by 1?

Change the "category" of the drops that you're putting inside of the mobs, if u put 3 objects with same category you'll only be able to take, at least, one.
