Is there a limit to how many magical tattoos can be applied to oneself? I know in Pathfinder and DnD they usually restrict you to one or two, but I was wondering if you were going to press any limit besides surface area.

I ask because yes, Hanzo is going to consider the tattoos. I haven't decided if that's immoral or improper for his culture yet, but I can go ahead and go on with it anyways because a badass warrior monk should deserve more badass-ness.
