The question about Magical Tattoos has been discussed in those threads linked above. Some will give examples of it being done, but most say it would be harder to justify. If you like the idea, I say do it, but research those threads and come up with your own answers for those questions when someone asks them before, during, or after a battle RP, so that you aren't only able to say: "Because I want to."
Being confident and well studied in the idea, and having good explanations for it, are the best ways to get your RP across the divides we have in RP in our community. If you want to just say the "because." you are welcome to that too, but it becomes a thing that other RPers worry about (sometimes to ridiculous lengths mind you) that you may just say the same thing to anything proposed no matter how implausible it is.
Take that with the jaded grain of salt it was given in, and you will be fine!
