Hidden Weapon Tattoo (Patreon)

Wondrous item (tattoo), rare (requires attunement)

You become attuned to this magical tattoo when it is inscribed on your skin. While you are attuned to the tattoo, you may perform a one hour ritual with a weapon you are holding. The tattoo absorbs the weapon, the design shifting to resemble it. You may have multiple Concealed Weapon Tattoos, each holding only one weapon at a time. These tattoos occupy the same attunement slot.

As long as the weapon is in its tattoo form, it is hidden. A suspicious creature must succeed a DC 20 investigation check to become aware of the tattoo’s nature. A creature who is aware of this practice must instead succeed a DC 15 arcana check to detect its magical nature.

You may use your bonus action to call the weapon forth, the ink forming the weapon in your hand. You can also use a bonus action to transform the weapon back into a tattoo as long as you are holding the weapon.

If you end your attunement to the tattoo, the weapon appears within 5 feet of you in an unoccupied space. You can no longer use the tattoo’s abilities until you restore your attunement and perform the ritual on a weapon.

These tattoos of questionable legal and moral origin are a favored method of assassins to smuggle poisoned weapons into high security areas. Finding one who can apply magical tattoos can be difficult as is, and finding one willing to apply one of this nature may require a back-alley deal. Regardless, once this tattoo has been etched into one's skin, their capabilities as an assassin become unmatched.
