Mana

Mana is Spyro's breath meter in The Legend of Spyro series. Since Spyro's breath is no longer an unlimited source of fire like in previous games, there was no limit on how many times Spyro could use his natural ability to breathe fire.

In The Legend of Spyro series, Spyro is limited by the amount of Green Gems that he collects. Each time Spyro uses a breath attack, the mana meter in the bottom right of the screen will go down unless refilled by picking up green gems from defeated enemies or Spirit Gems. This gives Spyro a need to either conserve his gems or find more before he can more easily take on the larger foes. As you progress through the game, you'll unlock new breath types to use in your fight against evil.
