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. For the specific details about the secondary resource bar, see the champion's page.

Energy
Champions who use energy as their resource:, , , and

Energy champions use an alternative to mana for spending on abilities. Having a maximum of 200 energy (except for Shen with 400 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.

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, the ultimate abilities of health-using champions are free of any cost; only gated by cooldown.
