Skill

Skill (能力) is an ability that, on rare occasions, can be acquired in recognition of some form of personal growth. Its acquisition happens by having it inscribed onto the Soul or Body by the World Language or by other skills.

They are like formulas that, once etched onto the individual, can be instinctively used without any practice, though their efficiency and effective use require varying amounts of practice and hard work, depending on talent and compatibility with the user.

Acquisition
An individual can gain Skills by using these five methods:
 * 1) By Birth or Evolution: Certain Races are born with Intrinsic Skills.
 * 2) By Proficiency: By achieving certain feats or by successfully using a skill without having it yet, the corresponding skill can be acquired directly by the individual in question.
 * 3) By Stealing from Others: Accessing the Body of an enemy breaking the Spiritual and Astral bodies of target like Razen does, or using skill-theft specific skills like Gluttony, Usurper or Mammon, allows one to acquire the target's skills.
 * 4) By Voluntarily Granting Duplicates of Skills: Through naming or via certain skills like Gluttony or Beelzebuth, it's possible to share one's skills with others.
 * 5) By Combining and Evolving Skills: By using certain skills like Degenerate that can fuse skills, or by taking advantage of the Harvest Festival, it's possible to evolve skills into stronger ones.

Obtaining new skills has the downside of permanently lowering one's Magicule capacity each time a new Skill is acquired. The amount of Energy that is converted to form the Skill depends on the Skills power. The capacity of skills is based on the body and Soul Force.

Individuals with a high Magicule capacity can gain skills more easily, while named individuals with stronger and more complete souls have a higher skill capacity.

Intrinsic Skills
Intrinsic Skill (固有スキル) refers to the innate Skills that certain Monster and Demi-Human races possess. They are generally the same for the whole race, but Unique Monsters can be exceptions, and higher evolution stages likewise usually grant more skills.

Common Skills
Common Skill (コモンスキル) refers to the most common of skills, which are usually easy to acquire.

Extra Skills
Extra Skill (エクストラスキル) refers to skills with power and efficiency magnitudes higher than those of Common Skills.

Unique Skills
Unique Skills (ユニークスキル) are fundamentally different from the lower skills.

There are times when the mold of one's mind and its powerful wishes give shape to skills. This is the nature of what is referred to as a "Unique Skill." The process to acquire one is impossible without a mighty Soul, but among such beings, some can even have two or three of them.

A unique skill is the shape of the mind itself, meaning that those with a particularly weak ego have no chance to acquire one themselves. In most cases, unique skills possess sub-skills in addition to their main ability.

Ultimate Skills
Ultimate Skills (究極能力) grant access to the ultimate principles of the world. The only way to combat an Ultimate Skill is to employ an Ultimate Skill as well. Just qualifying for an Ultimate Skill requires an extremely strong soul, will, and one to be a Spiritual Lifeform.

Like with unique skills, most ultimate skills also have sub-skills included and are unique to an Individual.

Resist Skills
Resist Skill (レジスト系スキル) refers to a type of skill that is generally passive and enables the user to withstand certain phenomena, both magical and physical. Among this type of skill are Resistance (耐性) and Nullification (無効) the former granting a high tolerance while the latter outright negates certain phenomena.

Resistance-type skills can be imbued into Barriers and Magic Equipment to amplify the Resistance-type skills effects even further.

Medical Skills
Medical Skills (特殊投与能力) are biotechnologically manufactured Skills.
