Dials

Dials are strange, mysterious devices made from the remains of particular shellfish, which have the ability to store energy and matter. The shellfish remains are gathered from the shallows near the shore of the White-White Sea.

Though they originate from Skypiea, some of them can reach and be used in the lower seas. There are many types of Dials that store various things depending on their type and most of them seem to be common throughout sky islands, though their rarity can vary by type with some being native to specific regions and some extinct. Dials come in many sizes and shapes, from the size of an average seashell to the size of a human. Dials store energy and matter itself, usually by that particular type of energy or matter being absorbed by a tiny hole or holes on one side of the Dial.

 The content can then be released by pressing the apex on the other side of the Dial. As long as they are not used or damaged, Dials seem to be capable of storing their contents indefinitely. If the shell of the Dial is broken they can become unusable. Dials based on clouds are rendered useless on the Blue Sea due to the inability of the clouds to survive at that atmospheric temperature and pressure. Dials are capable of letting the energy out in different amounts. Some use their contents all in one blast, such as Impact Dials, Axe Dials etc., while others are capable of storing multiple uses within their contents until it runs out, such as the Flame Dial, which then has to be refilled with that content for the dial to be used again.
