Some spellcasters permanently mark their bodies with symbols of their deity, eldritch runes, or ritualistic symbols. You can apply a focus tattoo over the course of a long rest, after which it functions as a spellcasting focus. Focus tattoos draw on a bearer’s own magics, and must be attuned like a magic item in order to function and require an attunement slot (information on attunement is in Trials & Treasures). When you cast spells with a focus tattoo in this way, you must briefly touch your focus tattoo with your free hand.
