"Mastery of the Sling Rings is essential to the Mystic Arts. It allows us to travel throughout the Multiverse. All you have to do is focus. Visualize. See the destination in your mind. Look beyond the world in front of you."
Karl Mordo[src]

A Sling Ring is a small two-finger mystical rings with the ability to create a dimensional gateway to another location or even a different dimension.

Theft of the Book of Cagliostro

The Ancient One leaving the Mirror Dimension

After the Ancient One killed several of the Zealots in the Mirror Dimension, Kaecilius used his Sling Ring to open a portal to flee to a park-like area. The portal closed before the Ancient One could follow. She used her own Sling Ring to travel back to the real world.[1]

Stephen Strange's Training

Karl Mordo training Doctor Strange on the use of the Sling Ring

At first, Doctor Strange found it difficult to use the mystic device, able to only generate orange sparks where his peers were able to summon full portals. As "encouragement" the Ancient One used her Sling Ring to transport Strange to Mount Everest and left him there with his Sling Ring. Strange managed to use his Sling Ring to get back to the Kamar-Taj before he froze to death.[1]

Battle at the New York Sanctum

Kaecilius and the Zealots used Sling Rings to travel to the New York Sanctum. When Strange managed to trap Kaecilius in the Crimson Bands of Cyttorak, the Zealot noticed that the amateur sorcerer had lost his Sling Ring, distracting Strange long enough for Lucian to stab Strange.[1]

Doctor Strange returning to the New York Sanctum

Doctor Strange used Kaecilius' Sling Ring to open a portal to Metro-General Hospital in search of Christine Palmer to fix his wound from Lucian Aster's attack. In his haste to seek help, he accidentally left the portal open, allowing the Zealots' Astral Form to follow.

After being saved by Palmer and dueling Lucain, Strange led Palmer to the janitor's closet where he showed her the opened portal; after stepping through back to the New York Sanctum, Strange used the Sling Ring to close the portal.[1]

Battle at the Mirror Dimension

During the Battle of the Mirror Dimension, Doctor Strange tried desperately to use his Sling Ring to escape the dimension, only for the Zealots to warp the world around the portal, causing Strange to lose his focus and destroy the portal. The Ancient One used her Sling Ring to enter the alternate reality to duel Kaecilius. Kaecilius let his Zealots attack her before stabbing her and using his own recovered Sling Ring to push her hundreds of stories to the mortal ground below. The sorcerers used their Sling Rings to escape the Mirror Dimension after the battle.[1]

Battle at the Hong Kong Sanctum

Kaecilius and the remaining Zealots used their Sling Rings to travel to the final Sanctum Sanctorum and destroy it. Doctor Strange and Karl Mordo used their own Sling Rings to travel to the same area. After the battle, Mordo left the Masters of the Mystic Arts and took his Sling Ring with him. Wong and Strange presumably used their Sling Ring to return to Kamar-Taj.[1]

Finding Odin

Loki is sent away to an unknown dimension

"This isn't me."
Thor and Loki[src]

In 2017, after discovering that Thor and Loki had arrived on Earth, Doctor Strange used his Sling Ring to open an Inter-Dimensional Portal in order to transport Loki away. After Thor arrived at the New York Sanctum, Strange used a strand of Thor's hair to create a spell, which he used in conjunction with his Sling Ring to create a portal to Norway, where Odin was located. Strange then used his Ring to open another portal, causing Loki to land in Sanctum before sending the two through the portal to Norway.[2]

Attack on Greenwich Village

Upon hearing Bruce Banner's warning of Thanos' arrival, Doctor Strange used his Sling Ring to find Tony Stark and bring him in the New York Sanctum. Later, during the fight against Ebony Maw and Cull Obsidian, Strange used his Ring to transport Banner to safety upon seeing that he couldn't turn into the Hulk.[3]

Doctor Strange and Wong fight Ebony Maw

Wong and Strange both used their Sling Rings to redirect Maw's projectile attacks, injuring the alien in the process. Wong used his Sling Ring again to save Stark from being defeated by Obsidian as well as severing the giant's arm in an attempt to trap him. Upon discovering that Strange was abducted, Wong used his Sling Ring to return to the New York Sanctum to protect it in Strange's absence.[3]

Battle of Titan

Spider-Man attacks Thanos


After a brief skirmish between the Avengers, Doctor Strange, and the Guardians of the Galaxy, they came up with a plan to subdue Thanos once he arrives on Titan. Strange used his Sling Ring to assist Star-Lord in planting a bomb on Thanos' back, then again to assist Spider-Man in attacking the Titan, but the latter two were subdued in the process. Once the Guardians and the Avengers were able to successfully hold Thanos, Strange used his Sling Ring to transport Mantis on top of the Titan's head to hypnotize him. However, this assault became compromised once Star-Lord found out about Gamora's demise. Once Thanos was able to complete the Infinity Gauntlet, he used it to eradicate half of all life in the universe. Doctor Strange was among the unlucky half to vanish, and his Sling Ring vanished with him.[3]

Battle of Earth

Avengers and other heroes arrive to battle

"Doctor Strange was there, right? and he was like "It's been five years, come on, they need us." And then he started doing the yellow sparkly thing he does all the time."
Spider-Man to Iron Man[src]

In 2023, the Masters of the Mystic Arts used their Sling Rings to summon portals transporting the restored Avengers and their would-be allies to the ruins of the New Avengers Facility in order to participate in the final battle against Thanos.[4]


Sling Rings are used by the Masters of the Mystic Arts to facilitate long distance travel where a temporary portal is desired. Sling Rings are worn on the second and third digits of the left hand when conjuring a portal, and this is achieved by the wearer tracing their right hand in an anticlockwise circular pattern while focusing on a destination beyond the space directly front of them. Most of the time they are simply carried until needed, typically somewhere on a user's belt. Each ring is uniquely crafted for its wearer.


Behind the Scenes

  • While most of the magic and artifacts in Doctor Strange are taken straight from the comics, the Sling Ring is an original item created specifically for the Marvel Cinematic Universe. Director Scott Derrickson explained, "The gateways, the forming of the gateways that are used for that, that's straight out of the comics. I just needed an object for them to carry it on."[5]
