Maybe you should read the whole issue again so you can understand what actually happened.
Once again you are the only person saying that is Set.
I said from the start that this was the serpent crown which you ignored as I recall you were saying this was actually Set they were fighting when you initially brought this up.
When I explained the premise of the story and the bits you are leaving out to try and play up what happened in the story you again fall back to untruths after you just posted what happened in the story.
It was even explained that while putting on the serpent crown it is drawing away your energy to summon set in this storyline(one of his acolytes mentioned we now give set what he gave us as they took of all the crowns) which would subsequently make the Serpent crown body immune to those powers that it had already absorbed. Strange's coporeal body had on the crown while he was in his astral form before all this even happened.
So how your getting the BS that Strange can't regularly hurt Set or the serpent crown's body is you relying on PIS.
LOL at Strange losing to Dracula if you actually read that issue all we saw of there fight was Dracula biting Strange at the beginning of an issue but then Dracula ends up losing to vampire Strange so moot point is moot.
