Let me show you how to do this-

Prompt 9: The second component is the Godspawn’s eldritch sigil: a design that symbolizes the creature’s extradimensional nature. Your character must draw it—and so must you! Is it dug into the ground with a stick? Did you trace it in ash on stone? Your own blood—or its blood—on paper? Show it!

Bertrand wastes no time showing Kai how to draw the Eldritch sigil, pricking two fingers to use his blood in lieu of paint.  Judging by the look on Kai's face, this way of drawing is... less than normal.

(Thank you  SchwarzerAlptraum for once again letting me borrow Kai!  I apologise for the switch up between Bertrand and Little Dead Hood though.)
