Kill6BillionDemons II: The Successor's coming will be followed by 108 burning threads

I go with the "Incubus is a projection/extension and not as powerful as he is normally." theory.

Still, interesting he is still hanging around. Wonder if its intentional of Allison or not.

Well there's actually multiple questions there.

Incubus' body is pretty beaten up and he appears to be blind.

So there's basically 2 questions:

1) How powerful is Incubus' dream projection compared to his physical body

2) How powerful is that compared to the other Demiurges? Per the author, he is ranked 4th in Demiurge power, behind Jagganoth, Solomon David, and Gog-Agog.

Even if his Astral (or physical) body were weaker, would it still be more powerful than Mammon or Mottom?

As we've already seen, he can make multiple copies of himself at the same time and alter his physical being in the dreamworld.

Perhaps what we're looking at here is different bodies, different strengths, where his Astral body is far more powerful in terms of magic and flexing his Key, while his actual body is more of physical threat with swordsmanship and speed.
