Elemental Power is the energy present in the element(s) molecules
Soul Masters's control over Elemental Power depends on their Elemental Affinity Physique, Spiritual Power, as well as their comprehension over the elemental laws.
The Ultimate Element is achieved when the purest form of an element reaches the pinnacle. It is able to not only suppress weaker forms of the same element, but also overpower and take control of it. Normal weaknesses do not apply to these elements, and are nullified in the face of the Ultimate Element, unless it is of the same tier.
SKILLS FOR ELEMENTS
1) The Elements' Heart was only significant to elemental-type soul masters. If they wanted to gain true power, then they had to understand the heart of the element they controlled. An element's heart was its essence and as long as one grasped it, not only could one draw upon the power within themselves, they could also tap into the elemental power found in the atmosphere. It was an ability that allowed one's strength to reach beyond their soul power.
2) Elemental Stripping is a skill that reduced some or gradually the whole element in a certain area while Elemental Imprisonment is a skill that forbids or limits the usage of one or multiples elemental abilities and energies within its range instantly.
3) Elemental Devouring is a higher technique form that swallows the element and siphons it to the controller, making it useless for the opposing party to even resist.
