I would like to add magical tattoos for a D&D campaign in 5th edition.
In 3e (The version that exposed me to D&D), there is the option to add tattoos with magic; They are permanent and can never be lost, but cost twice as much as an item with the same abilities.
However, there are no such rules for magic tattoos in 5e. I am only using the PHB, DMG, MM, XGTE, VGM, GGR, and MTF.
Are there any guidelines for magic tattoos in D&D 5e?
