# Energy Energy is a general term for a resource that is used to perform certain actions. On NA there are 3 main sources of energy: Chakra, Stamina and Double jump. These energies are additionally explained by [the player tutorial](https://narutoadventures.gitbook.io/wiki/basics/getting-started/the-player-tutorial).

♨️ Chakra

Chakra is the resource required to cast [jutsus](https://narutoadventures.gitbook.io/wiki/basics/jutsu). A player's chakra is found to the right of their health bar at the bottom of the screen , or alternatively by using [/menu](https://narutoadventures.gitbook.io/wiki/useful-commands):

Further [player ranks](https://narutoadventures.gitbook.io/wiki/player-ranks) get larger maximum chakra reserves and regeneration rates (per 2 seconds). They are as such: * Genin - 200, chakra regeneration 1. * Chuunin - 300, chakra regeneration 1. * Jounin - 400, chakra regeneration 2. * ANBU - 500, chakra regeneration 2. * Character - 600, chakra regeneration 2. When missing the chakra required to cast a certain jutsu, the caster sees the following message in chat:

and is unable to cast the jutsu until they regenerate the required amount of chakra for the jutsu. #### Chakra renegation To regenerate chakra a player must **hold shift.** While holding shift, particle effects will emit the player's body indicating that chakra is being regenerated. Changing the colour of these particles is possible through [donating to the server](https://narutoadventures.gitbook.io/wiki/donator-perks). Additionally, certain jutsus are able to boost chakra regeneration, or steal chakra from other players.

🏃Stamina

Stamina is the resource used to perform [weapon skills](https://narutoadventures.gitbook.io/wiki/gameplay/weapons#weapon-skills) using [weapons](https://narutoadventures.gitbook.io/wiki/gameplay/weapons). It is indicated while an weapon is being held by a player in the form of a green circle above the player's hotbar

. Using [weapon skills](https://narutoadventures.gitbook.io/wiki/gameplay/weapons#weapon-skills) will drain the stamina from the gauge. While the stamina gauge is empty a player will not be able to perform any [weapon skills](https://narutoadventures.gitbook.io/wiki/gameplay/weapons#weapon-skills) until the required amount of stamina is regenerated. Stamina is regenerated passively over time.

🦘 Double Jump

Double jumping is a movement feature on NA, to double jump, players must double click their jump key (space bar by default, see [tutorial](https://narutoadventures.gitbook.io/wiki/getting-started/the-player-tutorial#double-jump-tutorial)). Double jump has two charges indicated by the bar on the **right side** of a player's screen:

Double jump charges are regenerated at a rate of **1 charge / 10 seconds.**
