Magical Tattoos

Blending magic and artistry with ink and needles, magic tattoos imbue their bearers with wondrous abilities. Magic tattoos are initially bound to magic needles, which transfer their magic to a creature.
Once inscribed on a creature’s body, damage or injury doesn’t impair the tattoo’s function, even if the tattoo is defaced. When applying a magic tattoo, a creature can customize the tattoo’s appearance. A magic tattoo can look like a brand, scarification, a birthmark, patterns of scale, or any other cosmetic alteration.
The rarer a magic tattoo is, the more space it typically occupies on a creature’s skin. The Magic Tattoo Coverage table offers guidelines for how large a given tattoo is.
There are two main types of Tattoos - ones that require Gemdust (Stat impacting) and ones that use runes & Lykeum.
