By the end of "Deathly Hallows", Harry possesses all three Deathly Hallows: the Cloak of Invisibility, the Resurrection Stone, and the Elder Wand, They are three of the most powerful magical items in all of the wizarding-world. However, Harry lost the Resurrection Stone inside the Forbidden Forest, and decides to leave it there. Harry also takes the Elder Wand and lays it with Dumbledore's body, so the power of the wand might be extinguished if he dies a natural death.(In the movie, Harry destroys it by snapping it in half.) However, the new portrait of Dumbledore in the Headmaster's Office agrees that Harry should keep the Invisibility Cloak for himself, since it was his father's.
