Ability resources are tangible resources that are given as such by the game, meant to limit or empower a champion's gameplay in various ways by consuming or generating them with actions such as ability casting or basic attacking. They are shown on a champion's health bar. Each champion is limited to a maximum of two resources, a primary one (displayed in the "resource" line under the current health line) and a secondary one (displayed at the bottom of the health bar, either as pips or champion-specific icons).
This page provides a compilation of all resources and other related matter. For more details, visit the respective pages that are linked.
Mana[]
- Main article: Mana
Mana is exclusively a primary resource and is used by the majority of champions. It is usually expended through ability casting, and is designed as a gating mechanic to that ability casting, meaning champions cannot cast their abilities too often and incur multiple ability costs without running out of it. Its regeneration rate is low and it has a limited pool in abscence of bonus mana or mana regeneration obtained through growth and various other effects.
Manaless[]
- Main article: Manaless
"Manaless" is a broad classification that comprises all champions which do not utilize mana specifically as a resource. However, many of them may use any variety of other resources in place of mana, or otherwise no resource at all. There are 27 manaless champions:
Aatrox, 
Bel'Veth, 
Briar, 
Swain and 
Yone specifically use a resource that serves as a duration indicator for the purposes of specific abilities.
- Resourceless
Of the above, the following champions do not utilize any primary or secondary resource. There are 6 resourceless champions:
Energy[]
- Main article: Energy
Energy is an ability resource used in place of mana. It is also used as a gating mechanic for ability casting, but its regeneration rate is much higher and its pool cannot be improved. As a consequence, casting too many abilities at the same time will deplete it quickly, leaving the user unable to cast again for a short period of time while it regenerates. There are 5 energy champions:
Fury[]
Fury is an umbrella term for a multitude of resources that are telegraphed as so in the game, though each one has unique, champion-specific elements. Fury represents momentum and encourages sustained aggression from users, often gating a power-spike or empowerment. The user is rewarded for regularly cycling its accumulation and expenditure. While mana and energy have a base quantity provided by default, fury must be generated first in order to be usable.
This resource's generation varies between users, but is always done in-combat, and it may or may not decay when out-of-combat. Certain kinds of fury may also have some additional functions on top of basic attack or ability enhancements, such as a transformation. Fury's color varies between users from red at all times, to progressing from white or yellow to red as the bar is filled.
- Gnar's Rage
-
- See: Gnar
Gnar generates fury over time after dealing or taking damage. Upon reaching the maximum, he transforms into Mega Gnar, gaining different abilities as well as the ability to cast his ultimate, and his rage begins to deplete over the duration, transforming back to 
Mini Gnar when fully depleted.
- Renekton's Rage
-
- See: Renekton
Renekton generates fury upon landing basic attacks and hitting abilities. While above the threshold, his next basic ability consumes some fury to gain enhanced effects.

Haymaker, he stores a portion of the damage taken as Grit up to a cap, which quickly decays when not damaged. When Haymaker is activated, he consumes all Grit to gain a 
shield and deal damage based on the Grit consumed.
- Shyvana's Dragon Fury
-
- See: Shyvana
Shyvana generates fury naturally and with her basic attacks. With enough fury, she may cast Dragon's Descent at the cost of depleting all of her fury over time.
- Skaarl's Courage
-
- See: Kled
When Skaarl's health drops below 0, she flees from the battlefield, dismounting Kled. The player can afterwards restore Skaarl's courage by performing various actions, such as attacking and taking down enemies. Once fully restored, they remount and a portion of Skaarl's health is restored.
- Tryndamere's Battle Fury
-
- See: Tryndamere
Tryndamere generates fury with his basic attacks and some of his abilities. It grants him 
critical strike chance and he may consume it to increase 
Bloodlust's healing.
- Udyr's Awakening
-
- See: Udyr
Udyr charges up for an Awakening passively and upon triggering 
Monk Training attacks. Upon the resource filling up and Udyr entering a stance, he may cast the respective ability of his active stance again in order to empower it for a duration, consuming all Awakening charge in the process.
- Vladimir's Crimson Rush
-

Transfusion. When the second charge is gained, he gains its effect for a short duration, causing his next cast of Transfusion within to be empowered.
Shield[]

Flow[]
- See: Yasuo

Blood Well[]
Blood Well is a resource that thematically represents draining the life force from enemies. It is generated through a champion's own empowered form, and can be refreshed by passing a certain condition during combat. Blood Well depletes at a certain rate automatically, different for each champion. Only Aatrox currently uses this resource as a primary one, as the other champions use Mana as well.
- Aatrox's World Ender uses Blood Well while his empowered form is active.

Heat[]
- See: Rumble
Rumble generates heat whenever he casts a basic ability, and loses a portion of it over time after not casting for a period of time. While above the threshold, his basic abilities are empowered.

Daredevil Impulse (innate) and has a maximum of 6 stacks.

Style is displayed below Samira's health bar as pips. The first three pips have a white color, the next two have a yellow color, and the final one has a red color.
For added flavor, the player sees Style as six grades next to her health bar as well, from lowest to highest: 
.

For the player, pips will also appear on the side of the screen when there is 10 moonlight or less remaining in his main weapon.
Ammo[]
- Also see: Health bar#Champion ability indicators

Trivia[]
- When the mechanic was unique to Renekton, Fury was known as "Rage".
- When HUD animations were first revealed on the PBE, Tryndamere, Shyvana and Renekton's resources were described as Battle Fury, Dragon Fury and Rage, respectively.[1]
- When HUD animations were first revealed on the PBE,
- Gnar's Rage was once named "Tantrum".
- When Riven was first released, she was not technically classified as manaless. For example, she could purchase mana and it would be represented in her resource bar, allowing her to increase her 0 mana and 0 mana regeneration and benefit from items such as Manamune and Archangel's Staff. A hotfix was released to remove this interaction shortly after.
