This magical strand of thread must be woven into an existing magical cloak or garment, such as a cape of billowing, or a cloak of the mountebank, in order to function. This process takes 6 hours. For each positive point of Wisdom modifier of the tailor, subtract one hour from the total time required to incorporate this magical thread motif into your garment. For every negative point of Wisdom modifier, add an additional hour to the time.

The embroidery thread of non-detection bestows advantage on all saves against any divination spell or magical effect which targets you while wearing the magical garment into which this thread has been incorporated. Divination spells which do not allow you to make a save are unaffected.
