10 Most Powerful Items In The Marvel Cinematic Universe
3. Darkhold & Book Of Vishanti
It wouldn't be right to include one of these items without the other given that they're effectively the antithesis of one another, but on their own terms, the Darkhold and the Book of Vishanti are insanely powerful.
In Doctor Strange in the Multiverse of Madness, Scarlet Witch (Elizabeth Olsen) wields the Darkhold - a book containing dark magic spells of near-limitless power, which ultimately corrupts her mind in her quest to be reunited with the children she created in Westview.
The Darkhold basically allowed the user to do anything they wanted - such as navigating the multiverse and possessing other versions of themselves - while also massively boosting the powers of magic users. However, it also made them dangerously obsessed with the book.
Most perilously, the Darkhold could even cause the destruction of entire universes through the act of dreamwalking.
On the other hand, the Book of Vishanti basically gave sorcerers all the tools they needed to win, and in particular negate the effects of the Darkhold's magic, even if it was ultimately destroyed by Scarlet Witch.
When debating their relative power it's basically apples and oranges, but the abilities both books grant to their users is, frankly, too much for even the most well-meaning hero.
