Long story short, I'm making a Bloodhunter in D&D (uses their own blood to fuel their magic attacks) and for his character design, he has bloody marks over his body that are permanent. Anyone know what culture has runes/symbols/anything tbh that would look cool/be fitting to have be the makeup of these "blood tattoos" ? For reference, it's literally like how they made Aang's tattoos from the live-action film; that's what I'm imagining for my character.
