And honestly im not even sure if every tatoo represent some god
They do, it's part of the 'spoiler' part I don't want to talk about

the specifics are revealed in Inquisition.
Oh yes, THAT scene. I'm still getting over THAT scene.
AAAAANYWAY back to BG3 - yes I would very much like to see more animal-inspired designs, or trees, or war-paint, or just.. something that's more medieval-inspired or fantasy-inspired, rather than the modern-looking ones we currently have.

Body tattoos would be nice to see as well, not only the face.
