Defeats Ningal, another directly-empowered agent of the Dweller-in-Darkness(whose power is such that he can casually distort space itself) by trapping him in an arcane vortex and imprisoning his life-essence in mystic amber - DSMMA 37
Opens a fiery pit to the core of the earth to destroy two demons - DSMMA 38
Removes the evil half of the Shadowqueen, an evil sorceress empowered by the N'Garai (Spawn of the Elder God Chthon) and absorbs it into himself, then exorcises all of it from himself, expelling it from his being in the form of an enormous lightning bolt so bright it wakes most of Manhattan - DSMMA 44
Inscribes a mystic circle and seal using the very soul itself. Strange then wielded that power, described as pure life itself and capable of shaping or shaking a universe. He uses it to seal the doorway of the N'Garai into the human realm and banish the invading N'Garai - DSMMA 45
Cleanses himself of a poison that was seeping into his pores - DSMMA 46
The Eye of Agamotto pulls his foes into another plane of existence, against their will - DSMMA 46
Is able to hold his own against Ikonn, a mystical deity held in the same league as Cytorrak himself (both are Octessence wager members) and eventually banishes Ikonn back to his own realm by freezing his summoning bell in time, despite Ikonn defending his link to the earthly plane - DSMMA 47
The radiance of the Eye can rival the Sun's - DSMMA 48
Can review a hundred spells in an instant - DSMMA 49
Destroys Mordo's bodily form and disperses it across an entire dimension (Mordo at this point had spent months absorbing the mystic energies from a focal point between dimensions, through which their power flows) - DSMMA 49
The Eye of Agamotto's mystic light shatters Nightmare's mystical cage in his own dimension - DSMMA 50
Turns Tiboro into stone by manipulating the human egos he consumed - DSMMA 54
Even when heartbroken by Clea leaving him (he hadn't eaten for a week), he faces and overcomes D'Spayre, a Fear-Lord (like Nightmare and the Dweller) whose sphere of influence is despair, which made Strange especially vulnerable to him at the time. He recovers from D'Spayre's touch of fear (which impresses D'Spayre himself), dispels his illusions, and even overcomes his attempt to trick him with an illusion of Clea, before banishing him with the Crimson Bands - DSMMA 55
Humbles Margali of the Winding Road, Sorceress Supreme, in mystical combat - DSMMA 57
Neutralizes the power of the Darkhold, Book of the Elder God Chthon, by invoking the Vishanti in a spell to surround it in a Nirvalonic Sphere, from which he could read it safely. Despite the book possessing a mind of its own, and that it could marshal its own energies to attempt to kill Dr. Strange, the book was outmatched by Dr. Strange's spells. It is worth noting that such is the power of the Darkhold that when it was read out aloud for a day it summoned cataclysmic disasters that ravaged the world, boiling Atlantis' oceans and melting Wakanda's vibranium ore reserves to poison the ground - DSMMA 61
Despite earlier suffering a concussion, Dr. Strange seals a portal to an extra-dimensional plane after hurling all the invading demons back through it, and then proceeds to alter the memories of all the unfortunate party guests who bore witness to the event such that they never saw a thing - DSMMA 65
Blocks his own spell reflected back at him by Umar, who amplified its power a hundred-fold and manifested it as Faltinian Flame - DSMMA 69
