Skills ｢能力スキル, sukiru, lit. "abilities"｣ are a type of ability that, on rare occasions, can be acquired in recognition of some form of personal growth.

Properties
Skills are a type of special phenomenon activation system ｢特殊現象発動システム, tokushu genshō hatsudō shisutemu｣[1] that automatically perform inscribed supernatural effects known as powers ｢権能, ken'nō, lit. "authorities"｣. The nature of the power varies from skill to skill, some belonging to magic, some manipulating the world through purely natural means, while the most powerful among them are capable of bending the laws of the world to suit the user's will.

When a skill is acquired, it is chiseled into the person who awakened it. The exact location of the skill varies, with five different potential spots: the material body, spiritual body, astral body, soul, or heart core. Weaker skills typically reside within the body, while skills that are fully sublimated into their user are settled into the soul and are subsequently more powerful as a result.[2]

As long as the user has a sufficient amount of energy — soul force, Mana, magicules, etc. — they can instantly activate a skill just through a thought without any need to understand the mechanism behind it, having an instinctual awareness of its existence and how to activate it. Though it should be noted that the potency of the resulting power is determined by the willpower of the skill owner, two of the same skill can have a vastly different result when activated depending on the will that drives it. The inverse can also be true, with a powerful skill requiring an equally as powerful will to activate at all.[2]

Acquisition
The acquisition of skills happens under several different circumstances. Some skills are inherent to the physiology of the user in the form of intrinsic skills, others are obtained through mastering a certain power as an art and then desiring to obtain it as a skill, and in rare cases they can be obtained as a result of other skills.[1] Sometimes they can be inherited from parents.[3] The most powerful skills — special extra skills, unique skills, and ultimate skills — meanwhile, are obtained directly from the desires of the user simply by wishing for it.

In the process of obtaining a skill, the World Language will acknowledge the will of the user and a certain amount of magicules will be consumed to form the skill. Without a sufficient amount of energy, however, the skill cannot be obtained. Likewise, a lack of will and desire will also result in a failure. Other elements such as timing and luck can also play a significant factor as well.

Types
Intrinsic skills
Main article: Intrinsic skill
Intrinsic skills ｢固有能力スキル, koyū sukiru｣ are skills inherent to the physiology of the user, typically obtained from birth or through evolution. These skills can be broadly split into three different categories, these being species-specific intrinsic skills ｢種族固有能力スキル, shuzoku koyū sukiru｣, bloodline-specific intrinsic skills, and individual-specific intrinsic skills.

Common skills
Main article: Common skill
Common skills ｢コモンスキル, komon sukiru｣ are the most basic level of skills. They are typically limited to only a single effect without much flexibility, making them easy to master in exchange for a lack of versatility.

Extra skills
Main article: Extra skill
Extra skills ｢エクストラスキル, ekusutora sukiru｣ are a step above common skills in terms of power and versatility. They are the highest level of skill that can be obtained through effort and come in a wide variety of different powers.

Unique skills
Main article: Unique skill
Unique skills ｢個有能力ユニークスキル, yunīku sukiru｣ are special skills, typically only born from the strong emotions and desires of equally strong beings. Each one is unique to the user, acting as a reflection of their mind. Unlike common and extra skills, they can change as the user grows and matures.[2][4]

Ultimate skills
Main article: Ultimate skill
Ultimate skills ｢究極能力アルティメットスキル, arutimetto sukiru｣ are the highest level of skills, capable of rewriting the very laws of the world itself. They run on principles on a higher level than magic and make the user immune to lesser abilities under most circumstances.

Resist skills
Main article: Resist skill
Resist skills ｢レジスト系スキル, rejisuto-kei sukiru｣ are a type of skill that are generally passive and enable the user to withstand certain phenomena, both magical and physical. Resist skills are separated into two distinct levels: resistances ｢耐性, taisei｣ and nullifications ｢無効, muko｣. The former grants the user a high tolerance while the latter outright negates certain phenomena. Decipher this text in simple grade 5 terms
