A champion that is manaless does not use nor benefit from mana or mana regeneration. To date, there are 19 champions that do not use mana.

Of the champions the do not use mana, some utilize an alternative resource to cast their abilities.

These champions use health as their casting resource.

These champions use energy as their casting resource.

The remaining manaless champions have no costs related to their abilities.

Alternative Gating Mechanics

In place of or acting as a resource, there are a number of alternative mechanics that gate the availability of a champion's abilities.


Champions who use their own health as their resource:  Aatrox,  Dr. Mundo,  Mordekaiser,  Vladimir and  Zac.

These champions use their own health to cast some — or all — of their abilities. Champions can never kill themselves due to ability casting, as their abilities become free at critical levels of health. While these champions can cast their abilities more freely than most, their disadvantage is that frequent ability usage will bring them closer to death. With the exception of  Dr. Mundo's Sadism the ultimate abilities of health-using champions are free of any cost; only gated by cooldown.

It's worth noting that all of these champions have at least one ability capable of restoring their health.


Champions who use energy as their resource:  Akali,  Kennen,  Lee Sin,  Shen and  Zed

Energy champions use an alternative to mana for spending on abilities. Having a maximum of 200 energy with no growth per level, the main advantage of energy is its rapid regeneration (10 energy per second), so that energy champions are not at the risk of depleting their resource over an extended period of time. The main disadvantage of energy is that its small capacity restricts the rapid usage of multiple spells in a short period of time. The energy resource bar is colored yellow.


Unique to  Rengar, Ferocity is generated whenever Rengar lands an ability or passively during  Thrill of the Hunt. Rengar can have up to 5 Ferocity, and having maximum Ferocity allows Rengar to use one of his empowered abilities. Rengar's resource bar is divided into 5 sections that appear as he gains 5 Ferocity. While Rengar has between 1 and 4 Ferocity, the sections are colored white. Upon reaching 5 Ferocity, the sections are colored orange.


Fury behaves uniquely on each champion that utilizes it. The only consistent features are that each champion can generate fury on-hit or with their ultimates, and the resource bar is colored red.

Renekton's Fury is generated whenever he attacks an enemy, per enemy hit by  Cull the Meek and passively during  Dominus. If Renekton has 50 or more Fury, his next ability will be empowered at the cost of 50 Fury. Renekton's Fury will begin to deplete if he has not been in combat for 12 seconds. Due to  Reign of Anger Renekton's fury generation is boosted by 50% when he is under half health.


Shyvana does not have access to Fury until she has ranked  Dragon's Descent, and she gains a full fury bar (100) once she does for the first time. Shyvana's Fury does not decay and generates passively and whenever she attacks an enemy. 100 Fury is required to activate  Dragon's Descent, but activation does not instantly consume all her Fury - instead, it depletes slowly until it runs out. Shyvana can still generate Fury with her basic attacks while it is depleting.


Tryndamere's Fury is not required to activate any of his abilities, but  Battle Fury grants him bonus critical strike chance based on his current Fury and activating  Bloodlust will consume his current fury to empower it healing effect. Tryndamere generates Fury whenever he damages an enemy with his basic attacks or abilities, whenever he kills a unit and when he activates his ultimate, Undying Rage . Tryndamere's Fury will begin to deplete if he has not been in combat for 8 seconds.


Unique to  Rumble, Heat is generated whenever he casts one his basic abilities. Heat rapidly depletes if Rumble has not cast an ability in the last 4 seconds. Rumble gains different effects depending on his current Heat. Heat is displayed in Rumble's secondary resource bar, and is colored differently depending on the current amount.

  • 0 – 49 heat — No effect.
  • 50 – 99 heatDanger Zone.  Rumble's abilities gain additional effects.
  • 100 heatOverheat.  Rumble is silenced and his basic attacks deal additional damage until his heat reaches 0. Visually  Rumble's mech is colored bright red and you can hear his cries of discomfort due to the heat.

Other uses of the Secondary Bar

Some champions use the secondary bar to display some ability effects to track them better.

Blood Well

Unique to  Aatrox,  Blood Well acts as a health reserve should Aatrox take lethal damage - reviving him with an amount of health equal to the Blood Well's contents plus a base amount. The revival effect has a cooldown, and the current amount in the reserve is colored red or white depending on whether or not the effect is available. Aatrox fills the Blood Well by casting his abilities, with 100% of the health cost being stored in the Blood Well. The Blood Well slowly depletes if Aatrox has not taken or dealt damage recently.

Aatrox also gains bonus attack speed based on the contents of his current Blood Well, regardless of whether the revival effect is available.

Iron Man

Unique to  Mordekaiser,  Iron Man acts as a temporary, decaying, absorption shield that is generated by the damage he deals with his abilities. The resource bar is colored white.


Unique to  Yasuo, Flow is generated by movement, dashing, teleporting and the passive effect of  Wind Wall, requiring a total of 4000 traveled units to be fully filled. Maximum Flow is required to use  Resolve.

Flow is represented in Yasuo's resource bar and is colored grey while charging, and white once full to indicate it's a shield (as with  Mordekaiser's  Iron Man).

 Resolve: Should  Yasuo take damage from a champion or jungle monster his Flow will will turn into a shield for 1.5 seconds, after which- if it has not been broken- it fully depletes.


  •  Mordekaiser's  Iron Man,  Yasuo's Flow and  Aatrox's  Blood Well and are the only non-resource or alternative gating mechanics that is displayed in the resource bar.
    • It is currently being considered to have  Riven's  Runic Blade charges displayed in the resource bar, in a visually similar manner to Rengar's Ferocity. [1] If this change passes, similar changes may also be applied to similar mechanics (such as  Tides of Blood).
  • 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. [2]
  • When  Riven was first released, she was not technically classified as manaless - she simply had 0 (+0) base mana and 0 (+0) base mana regeneration. She could purchase mana and it would be represented in her resource bar - allowing her to use and benefit from items such as Manamune and Archangel's Staff. This was hotfixed shortly after.

    • Idk, that seems viable. Tell RIot about it!
    • You're right. A player not being able to immediately guauge how much shield he has is fairly crippling for them. Still, I enjoy being Morde...
