Sheikah Slate

The Sheikah Slate is a key item in.

Location and Uses
The Sheikah Slate is a multipurpose tablet bearing the Crest of the Sheikah. Link obtains it shortly after being awakened by a disembodied voice in the Shrine of Resurrection. Though Link has no recollection of seeing it before, he finds it familiar. He must first use it to get out of the Shrine of Resurrection.

The Sheikah Slate can be used to access the Map of Hyrule, which displays the current temperature and time, and any Pin and Stamp placed. It also grants access to any of the many Ancient Shrines and Sheikah Towers located across Hyrule. Link must activate the Sheikah Towers to extract the local Map to the Sheikah Slate. Link can use the Sheikah Slate as a Scope when the R Stick is clicked down. In addition to providing a closer view, the Scope ability provides a first-person view from which Link can set Pins.

The Slate is able to receive Runes, a form of information that bestows the device a number of different abilities. They serve as a replacement for traditional items such as Bombs. These Runes can be obtained and installed onto the Slate at the Ancient Shrines found in the Great Plateau.

The Camera Rune, the Album, and the Hyrule Compendium features are unavailable at the beginning, as they are encrypted in Sheikah text. They are restored when the tablet is brought to Purah at the Hateno Ancient Tech Lab. Included in the Camera's Album are 12 photographs which were taken by Princess Zelda 100 years ago. Upon completion of the Main Quest, "EX The Champions' Ballad", Monk Maz Koshia gifts Link the Master Cycle Zero Rune.

The Sheikah Slate makes an appearance in as part of Link's  Champion Tunic outfit and his Tunic of the Wild outlook. It is mostly only used to summon out a round Remote Bomb and to detonate it.
