So, you would like to create new item handler, (or put it into extractable?) I guess and use something like this
if (itemId = XX)
{
activeChar.addItem("Extract", 57, 1000000, activeChar, true);
activeChar.addItem("Extract", 1, 1, activeChar, true);
activeChar.addItem("Extract", 2, 1, activeChar, true);
}
Since EXTRACTABLE items can create just one item per time or maybe there is easier way.. :P
