A magical tattoo created with a special needle, emphasizing a single color. To attune, you press the needle to your skin throughout the process, and upon completion, the needle transforms into the tattoo. While the tattoo is on your skin, you gain resistance to a specific damage type associated with its color (chosen or determined randomly by the DM). Additionally, when damaged by the chosen type, you can use your reaction for immunity to that instance and regain hit points equal to half the damage. This reaction recharges at dawn.
