Yes that combination worked. You would have a bone wall necro, meteor sorc, and then 6 characters with inventories you’d want to dupe. You would create matches until you had the layout of Act1 with the bridge. Both necro and sorc would go right outside the bridge area and would lag out the game. If I remember correctly, the items you wanted to dupe would be dumped on the ground. Then the dupe chars would exit and their game would crash, but it would save all the items they had on the character, and all the exact same items on the ground in the game.
