Doctor Strange: 31 Easter Eggs & References You Must See
11. The Crimson Bands Of Cyttorak
Even when Doctor Strange is struggling to actually show off the magic that he has endlessly researched and trained to use for something like 5 years (or there abouts), he's capable of conjuring one of his most famous spells from the comics.
The Crimson Bands Of Cyttorak is a spell that sends red coloured bands of energy out of Strange's hands like whips to bind his enemies. While he's not powerful enough to make them as durable as they have been in the comics in the past (and while they're clearly not actually red), it does appear that he conjures the spell while fighting Kaecilius and his zealots at the New York Sanctum.
