Jump Pad

Jump Pad or Jump Device (점프 장치, Jeompeu Jangchi) is a type of Shinsu Teleportation Device that are very simple and common to be used in the Tower. The Jump Pad itself is like a giant circular ground platform.

Just like other type of similar devices, Jump Pad were created as additional technology to make Teleportation more common to use and more efficient without having to use Lighthouse for example. This device doesn't seem to be mobile though and once placed on certain area, it will not be able to move into different location.
