The blue Mana bar

Mana is the most common resource heroes use to cast abilities. Underneath your green Health bar a blue bar shows your Hero's Mana supply. Using an ability requires you to have enough Mana to fulfill it's Mana cost. If a Hero starts running low of Mana, the number of Abilities he/she is able to use immediately drops (they’ll turn dark purple in the Hero’s Ability list). Mana replenishes over time, but not always quickly.

Overview[edit | edit source]

Scaling[edit | edit source]

Heroes that use Mana start the game with 500 Mana at level 1 and gain 10 maximum Mana every level onwards. What this means is by level 20 mana users have a mana pool that is almost 40% larger and have over 60% more mana regeneration. Mana costs are constant, so as the game progresses mana becomes less and less of an issue. Some heroes can additionally increase their Mana cap through Talents.

Mana Regeneration[edit | edit source]

A hero's Mana restores over time based on their Mana Regeneneration. Mana regen is passive and continues even when a hero is disabled. Mana regen is measured in mana per second. Mana regen can be increased by some talents. Heroes that use mana, except for Gul'dan and Probius, start with 3 mana per second at level 1 and gain .0975 mana per second every level. There are also some abilities that can refund Mana if their requirement is fulfilled (e.g. Medivh's "Arcane Rift" refunds some of the Mana cost if it hits a hero).

Other Resources[edit | edit source]

Main article: Resource


Some heroes don't use Mana at all or use another resource similar to Mana. Heroes that do not use Mana include Abathur, Auriel, Chen, Cho'gall, D.Va, Fenix, Illidan, Junkrat, Lt. Morales, the Lost Vikings, Murky, Samuro, Sonya, Tracer, Valeera, and Zarya.

Core Concept[edit | edit source]

  • Mana is a limiting factor for self-sustain: Any hero who can use abilities to recover their own Health quickly, without taking risks, is generally be limited by Mana. This helps ensure that damage enemies deal to them actually matters and isn't just magically erased at no cost. Requiring Mana for HP sustain makes it possible to win wars of attrition and is one way to keep game length from spiraling out of control. Heroes who don't require Mana for sustain generally "pay" for their sustain in other ways (such as Auriel who relies on aggression to generate Energy), or have more modestly-paced sustain with adequate counterplay (such as Muradin, Illidan, Sonya).
  • Mana is a limiting factor for harassment: Ranged Assasins with harassment abilities, like Li-Ming, Jaina, Kael'thas, can wear down enemies before committing to a fight. At the same time, those abilities are packaged with significant Mana costs and/or Cooldowns that really give them weight - the cost of missing is not trivial, so it feels really good when you hit. It's important that something limits the frequency with which those abilities are used, and that enemies feel like dodging those abilities is meaningful.
  • Mana can be a very flexible resource:' Used properly, Mana forces you to think about your ability use in more of a long-term perspective beyond just "spam on CD". It can also serve as a limiter in cases where Cooldowns don't really factor in, such as Li-Ming's trait reset rampages. Interestingly, the degree to which Li-Ming burns her Mana before resets kick in ends up affecting how crazy she can go with those resets, so how you choose to spend your resources in that case has a big impact.[1]
  • Mana should be a meaningful part of the game, particularly in the early stages when wave clear is at a higher premium. As the game progresses, Mana tension should become less important as Heroes gain more base Mana and the game’s focus shifts to team fighting.[2]
