More noob questions! Or a question.
Is there a significance in the color of tattoos? And if there is, will that be allowed to a degree?
Each of the different tattoo colors represent a different emotion, which is the one the Demon chooses to utilize. Like Rage, etc, etc.
All the lore on the tattoos that we have are pure, 100% speculation and/or fan fiction.
Notably, you are not allowed to have laser beams coming out of your ritually blinded eyesockets.
