As a Transmuter Hayato is most efficient in changing the properties and shape of his aura. He has mastered his natural type aswell as one other type being Conjuration, he has now moved into his third category being Enhancement. He has mastered the four major principles though he despises one in particular being Zetsu, aswell as having mastered five of the seven advanced techniques with the exceptions of Ko and Ken so far though his skill in In and En are exceptional (his En reaching 50m comfortably and 70m with strenuous effort).
Hayato developed several abilities in which he grants his aura the properties of a blizzard, mainly meaning intense cold. His Nen becomes so cold that in order to even use it he had to first master Conjuration in order to form his typical outfit which protects him from the temperature of his environment.
Hayato Yamashita's Nen Type:Transmutation
Glacial Hand (KANJI HERE,JAPANESE ALTERNATE NAME HERE (IF APPLICABLE))
Hayato's most basic ability, consisting of him freezing whatever he touches. The actual freezing can scale from just cooling a drink as if it had ice cubes in it all the way up to freezing things solid. Though the name says "hand" Hayato can use this on any piece of his body at any time.
Warm Clothes (KANJI HERE,JAPANESE ALTERNATE NAME HERE (IF APPLICABLE))
The precursor ability that Hayato must make use of before he can truly unleash his Nen, this Conjuration ability crafts a set of clothes (Coat, pants, boots, and gloves) that appear over his body or clothing he is already wearing. These "Warm clothes" prevent Hayato's body from being affected by outside temperature changes aswell as automatically changing the temperature of air coming in and out of his body to keep him comfortable. It is important to note that these clothes ONLY protect against temperature, meaning that his own frigid Nen wont harm him nor would immense heat of a desert but these clothes provide absolutely no other protection. For instance if Hayato is wearing "Warm clothes" boots without shoes on underneath and steps on a nail it would feel as if he did so with his bare foot.
