Ahh! A spear! That is an excellent idea! Thanks @Vargo Seldon! And I can have Stormlight and still have the tattoos, as long as I view them as an extension of myself, right? Yeah.
Ok no I don't! I just have the Bridge Four tattoo that everyone gets (in the book) after they become Dalinar Kholin's guard/soldiers and the glyphs of the first oath of the Knights Radiant. So I was torn between the Cosmere symbol or and Aon. I'm covering my whole arm so space isn't an issue. But my left arm shall be all things Cosmere and part of my side too. But arm first.
