Yeh you are!,

the packet of items on the ground HAVE NO data to say if there plus 1/ Blessed/ Enchanted, the packet only gives the Items UID, Item ID, X, Y Position. Nothing more so leave it as no, carnt and will nvr be able to do so unless you make your own server, and restructure the Clients reading of Drop items packet to include if the items +'d, so dream on.
(Would require editing to the Server and Client, so i dont see it ever happening on Offical Co hahaah.

)
You see this topic come up all the time, noobs use search :S!
Btw, to the ppl who think that server decides if the items +'ed or not when you loot the item, your wrong.
All of the item details are within the Server, and only very little is sent to the client (enough to show what it is and the position is at), the server holds more behind it

.
This is the Packet sent Server>Client (Used in showing an item on the ground).
write_2bytes(20); // Packet Length
write_2bytes(1101); // Packet Type (44D)
write_4bytes(_ItemUID);
write_4bytes(_ItemID);
write_2bytes(_ItemX);
write_2bytes(_ItemY);
write_2bytes(1); //Always 1 (doesnt Mean anything)
write_2bytes(0); //2 blank bytes
As you can see nothing that contains if its +'ed, So nvr will happen, unless what i said above.
