And what looks like the item, is it a perfect copy of yours or the stats are somewhat random ?
e.g. if you have archmage' clasp with a low-35% recharge, can you expect a -40%recharge or higher ?
The items that drop from clone's corpse is copy of the items your hero wearing, with random stats( can be better or worse, its random).
But when you can use this " bug " any time, anywhere so you can get copy items with better stat quickly.
