Zora Tunic

The Zora Tunic is a type of clothing Link can wear in. It is visually identical to the Kokiri Tunic, except that it is blue, and it can only be worn while Link is an adult. This tunic can also be stolen by Like Likes.

Uses
The Zora Tunic allows the wearer to breathe underwater. While it is almost functionally useless by itself, it must be used in conjunction with the Iron Boots for this ability to really be brought out. The pair renders large undersea areas accessible and traversable, although at a slow speed. Unlike the Goron Tunic, it does not offer any mild defense bonuses: it does not reduce frost damage, only disables the timer seen underwater.

Location
The tunic can be bought by Link at the Zora Shop for 300 Rupees, or it can be given to him by King Zora when the young hero helps him to thaw out using the Blue Fire.
