Lisa's is a little different, as hers is an octagram. Hroptatyr's spell is a heptagram, which is nearly identical to the ones manifested by the Hypostases. It's infamously used by the esoteric cult of Thelema (the primary basis for the Narzissenkreuz) in their Seal of Babalon
Okay, enough time has passed
Can we address the elephant in the room????
This is Hroptatyr’s spell of the blessing/curse of Immortality in the cutscene… and well, Lisa’s charged attack.
