Stone Mask

The Stone Mask is one of the most valuable masks in Majora's Mask. The mask prevents most non-boss enemies from detecting Link. Link can therefore walk through most of Termina without worrying about being attacked.

Obtaining the Mask
To receive this mask, Link must use the Lens of Truth to find the invisible soldier Shiro in Ikana Canyon, and he will give the young hero a request. He will ask that Link cure him of his ailments; this is not done with the Song of Healing, however, but rather with a Red Potion. Once Link has given him one, he will hand over the Stone Mask in return.

Trivia

 * Even though the Blue Potion heals, Shiro will not accept it.
 * The mask will not work with a Garo Ninja or Iron Knuckle.
