I thought it was a nice little tryout for a Doc ongoing, but the story itself doesn't
deal with Strange's loss as much as it shows the results of it.
I get that this is an esemble book but the loss of a major character's soul needed to be addressed in a more detailed manner than an offhand remark.
And if Doc needed blood magic to defeat that thing he is offically a whole hell of a lot weaker than he was in his own book.
