Potential Tattoo Ink

You may spend 1 hour pouring this magical ink
onto your skin. A stinging sensation spreads
across your body as the tattoo forms across both
of your hands, in the shape and color of your
choice.
Once per day, as a reaction, when a creature
saves against your spell, you may speak the
tattoo's Command Word "potential" and the
creature must repeat the saving throw, taking
the new roll instead.
Requires Tattoo Attunement.
