WIZARD PK RING. (Jan 2006) Designed by World Magic Shop. (This is a substantial improvement on the principle of the Elohim Ring, the MasteRing and the Emerson & West Ring.) The "new" rings on the left were released within weeks or months of the Wizard PK Ring and the creator of the Incarnum Ring says on a Malaysian Magic Forum that he is "piggybacking on the marketing of the Wizard PK Ring"
