Remote Bomb (Rune)
Breath of the Wild
The Remote Bomb rune is obtained in the Ja Baij Shrine while exploring the Great Plateau. It allows Link to create a spherical or cube-shaped Bomb that can be detonated on command using the Sheikah Slate. Remote Bombs can also be detonated by shooting a projectile at them, though this is largely unnecessary; enemies can also intentionally or unintentionally detonate them as well. Like Bombs in other games, this Rune can be used to blast away certain obstacles, such as cracked walls or a pile of boulders. They can also be used to damage or defeat enemies from a distance.
The spherical Remote Bomb will roll away from its position, which is useful for blowing up locations down a slope or in otherwise unreachable areas. The cube-shaped Remote Bomb will stay in its place, and can be used for easily reachable locations. After detonating a Remote Bomb, a timer will appear that will restrict when Link can create another Bomb. Besides this restriction, there is no limit to how many Bombs can be created or held at once, and it is possible to create both a single cube-shaped and spherical bomb to be placed in tandem with one another, with the timer being tied to the shape of the bomb, allowing for simultaneous detonation.
This Rune can be upgraded if Link visits the Hateno Ancient Tech Lab and speaks with Purah. She will allow Link to use the Guidance Stone in order to upgrade to the Remote Bomb+, which features a shorter cool-down.
