== Powers, Skills & Abilities ==
Back when it was the Heart of Tengu it can protect its keeper from attack, its main ability was enabling whoever possessed it to control the five elemental mystics who served the Demon Shredder. 
It is assumed that this artifact was created by the Ninja Tribunal at some point before or after their victory over the Demon Shredder as a way to keep these powerful Mystics in check as their master was. 
The Utrom Shredder somehow came into possession of the Heart and used it to control the mystics.
Although it appeared that the mystics were loyal to Ch'rell, it was later revealed that they were disgusted by their servitude; thus, they hatched a plot to resurrect their master by using an invisible bone demon to gather his helmet, gauntlet and body from the Ninja Tribunal. 
The demon was defeated by Master Splinter and the Ancient One, and it is unknown if the mystics made any further attempts to free themselves, but their mistreatment at the hands of Ch'rell reignited their desire to return to their true master.
To this end, the mystics tricked the E.P.F. into stealing the artifact and destroying it, finally freeing them from the Foot's control. 
When it became the Heart of Earth, Adam transferd all the powers from his Heart induced body into the formerly destroyed necklace and can turn the Five N.I.N.J.A.S. into the Foot Mystics but thanks to Adam's Golden Power, the evil was removed and became usful to use help Adam.

It was later revealed that the Golden Power was mixed into the Heart also:
* Nigh-Omnipotence - The user is virtually omnipotent (unlimited in power, unless part of the power is taken from them, in which they have a limited amount of power left), like when the First Spinjitzu Master used this elemental power to create Ninjago (using the main elements that make it up). Another example is when the Overlord became the Golden Master, he wanted to use this elemental power to destroy all of Ninjago. The user does not need materials around them to create objects using Creation. Unlike Creation, the Golden Power can be used for offensive energy attacks, and its "constructs" are mostly made of energy rather than matter. The user is able to use the five main elements that comprise it (including Energy).
** Potentikinesis - The user can manipulate various superpowers and elemental powers.
*** Power Granting - The user can give elemental powers to other people.
*** Power Restoration - The user is able to restore the power of others.
*** Power Enhancement - The user can increase their power thousandfold.
*** Power Removal - The user can remove an Elemental Master's powers and use it for themselves.
** Flight - The user can freely fly in the air.
** Elementumkinesis - The user can create, shape, and manipulate the basic elements of nature (Fire, Earth, Lightning, and Ice). Capabilities may include moving, altering, and mixing existing elements. The user has control over four other elements - Fire, Ice, Earth, and Lightning. He can use them as vividly as the specific master of those elements can but has full control over them.
*** Pyrokinesis - The user can create and control fire.
*** Geokinesis - The user can create and control earth.
*** Electrokinesis - The user can create and control electricity.
*** Cryokinesis - The user can create and control ice.
*** Elemental Blasts - Users of this element can fire blasts of the main four elements with the Golden Power, usually as an offense.
** Telekinesis - The user can influence, manipulate, and move objects and matter (because it is comprised of the elements that Golden Power controls) from great distances, usually to attack or defend against an adversary.
** Ergokinesis - The user can manipulate a stronger form of Energy, usually to attack an adversary (the Golden Master can generate powerful beams composed of gold-colored energy).
** Meta Matter Manipulation - The user wields a stronger form of Creation (even stronger than the Tornado of Creation), usually to attack or to defend against an adversary.
*** Omnifabrication - The user can create, reshape, and move objects or matter to create anything they want/need.
*** Materialization - The user can create organic and inorganic matter from nothing either as finished objects or simply unfinished elements.
**** Remote Materialization - The user can create and reshape all kinds of things in distant and far off places without the user even being present.
**** Life Creation - The user can create life.
** Spinjitzu, Forbidden Spinjitzu, and Airjitzu - The user can do Spinjitzu and Airjitzu. Anyone can do Spinjitzu and Airjitzu with immense skill, but the user can do Golden Power Spinjitzu and Airjitzu. It is possible the user can do Forbidden Spinjitzu too.
** Golden Influence - The user can send golden waves to weaken enemies.
** Golden Beam Emission - The user can shoot a blast/ray of Golden Power/energy from his hand. The user can make a beam of Golden Power with two hands which is a more powerful version of the ray. This move is usually done with two hands as it requires more energy.
** Golden Shields - The user can make or encase himself in a Golden Power shield/dome/field.
** Chryso-Photokinesis - The user can create a golden-colored light.
*** Golden Purification - The user can heal themselves and other people from any injuries and Dark Matter.
** Powerful Artifact Creation - The user can create powerful artifacts, like the Realm Crystal.
** Dimension Travel - The user can travel to another realm with this power as when the First Spinjitzu Master left the First Realm.
