"That's the Stone Mask, isn't it? That is a fine mask. It is filled with an appreciation for things that go unnoticed." -Happy Mask Salesman
The Stone Mask grants the wearer the power of stealth rendering them invisible to enemies. When Link is wearing this Mask he can sneak past most of the enemies in Termina without being noticed.
How To Obtain
To obtain the Stone Mask, Link must give Shiro, a Clock Town Solider, a red or blue potion. Shiro is found sitting down in a circle of rocks on the Road to Ikana. Link must use the Lens of Truth to see Shiro.
