Wondrous Item (tattoo) , Uncommon (attunement/varies)
This magical tattoo contains the essence of a level 1-3 spell chosen by the spell's creator. While the tattoo is on your body, you always have the associated spell prepared, and you can cast the spell using any spell slots you have of the appropriate level. If you have the Spellcasting or Pact Magic feature, the spell uses your spellcasting ability; otherwise of this spell requires a saving throw or an attack roll, the spell DC is 13 and the bonus is +5. If your attunement to the tattoo ends, the spell vanishes.
You can also cast this spell once without a spell slot and spell components. Once the spell is cast this way, the tattoo vanishes.
Greater Anguisian Spell Tattoo. The spell level the tattoo contains raises to 4-6, and no longer requires attunement.
