Cryonis

Cryonis is a Rune ability in. The Rune allows Link to create pillars of ice from a water's surface.

Location and Uses
The Cryonis Rune is obtained in the Keh Namut Shrine at the Great Plateau. The Cryonis Rune allows Link to spontaneously create pillars of ice from the surface of any body of water. When activated, the Rune creates blue grid lines across areas where there is sufficient water. From this area, Link can create a pillar of ice that will raise up from the water. Link can create up to three pillars of ice at once; raising a fourth one breaks the first. In addition to creating pillars of ice, Cryonis can also be used to break them as well, as indicated by a hammer cursor. After using the Cryonis Rune, a timer gauge will appear which must reach full before Link can use Cryonis again.

The ice pillars created have various uses, and can be used as stepping stones, leverage, obstacles, as well as to manipulate certain surroundings, such as opening a gate by raising a pillar beneath it.
