This won't work. If you kill a gremlin, a server sends you a packet with items dropped on the ground and at the same time it saves the data into db. So if you edit that pack, you could see gremlin dropping 1kk or whatever but it will always be CLIENT side only. The 'real' value is stored in the db and you can do nothing about it. Editing packets from server is just a waste of time since the change will always be only client side. Only way to hack packet modification is to modify outgoing packets(=packets from client) :)
