An element is one of the technique types that determines the set of elemental abilities available to a character. At the start of the game, a character's element is determined using Chakra Paper.
The game features five basic elements: Water, Fire, Lightning, Earth, and Wind. Some clans have an innate affinity for certain elements. For example, members of the Uchiha clan have an affinity for Fire, and the Hoshigaki for Water.
Each element has its own set of elemental techniques available to characters with the corresponding element.

Water is an element associated with the use of water techniques and the control of large volumes of water.
