For those who may wonder what the sigil does to adapt to the succubus form (the original one really should be a complete independent form in 3D): I figured, what does a succubus use for energy in the first place?
So it's a kundalini snake produced from the tail, but aimed forward and the mouth of the snake is simultaneously a vagina, removing the actual gut itself and using the ability to absorb energy in the way a demon would instead.
