9. An Infinity Stone
The Eye of Agamotto has the power to manipulate time, and allows Doctor Strange to both create time loops and even reverse it so he can save the lives of everyone in Hong Kong after Kaecilius opens up a portal to the Dark Dimension. Many fans suspected that the Eye would be revealed as the Time Stone, and that happens in the final few moments of the movie when Wong casually mentions that it’s one of the Infinity Stones. The hero’s mentor also points out that Earth is going to come under fire from new magical and cosmic threats now there’s no longer a Sorcerer Supreme, and Thanos will no doubt be among them!
