Quilllen Carves the Sigil

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!

Quillen uses one of his quills to carve the sigil into a tree.
