Thief's gloves - 4 items on champion.

If you build thief's glove on a 1 star unit then build recurve bow on another 1 star unit you have in your base you are going to end up with 4 items once you upgrade to 2 stars.

Doesn't work with 2 whole items.

Doest work with one whole item either.

Haven't tested with any other single items other than recursive bow yet.
