Nature Transformation

Nature Transformation is an advanced form of chakra control that entails the moulding and defining of the nature of one's chakra, altering its properties and characteristics for use in techniques. Nature transformation is one of two necessary components for creating or modifying a technique, the second component being shape transformation. While nature transformation changes the properties of the chakra, shape transformation changes the actual form and movement, altering its abilities.The release of elemental chakra is typically suffixed with Release.

Basic Nature Transformations
The Five Elements are the five elemental chakra natures, which are the foundation of all elemental ninjutsu. They are so vital to the shinobi lifestyle that each of the Five Great Shinobi Countries is named after one of the five. Each element is naturally weaker than and stronger than another:
 * Fire Release is strong against Wind but weak against Water.


 * Wind Release is strong against Lightning but weak against Fire.


 * Lightning Release is strong against Earth but weak against Wind.


 * Earth Release is strong against Water but weak against Lightning.


 * Water Release is strong against Fire but weak against Earth.

Basically, if an elemental technique is put against another elemental technique of the same level, but of a stronger nature, then the technique with the superior nature will prevail. However, a technique with a weaker nature can overpower a technique with a stronger nature if the former is of a higher level.

A similar principle applies in how technique of the same element interact, what is called counterbalancing. If two techniques of the same nature and the same level are used against each other, they will cancel each other out.

Affinity
In general, every person's chakra has an affinity towards one of the five basic nature transformations. Affinity can at times be genetic, or at least common to a particular family; most members of the Uchiha clan have an affinity towards the Fire nature.
 * Fire: the paper will ignite and turn to ash.
 * Wind: the paper will split in two.
 * Lightning: the paper will wrinkle.
 * Earth: the paper will turn to dirt and crumble away.
 * Water: the paper will become wet/damp.

Shinobi have an easier time learning to create and control a chakra nature that matches their affinity, although even then it may take a number of years. Shinobi are not limited to the nature they have an affinity for, and it is in fact common for jōnin to have mastered two natures.
