Cast from Hit Points: Difference between revisions

* In [[Fushigi Yuugi]], Mitsukake can only use his [[Healing Hands]] once a day because of this. {{spoiler|When he overdoes it towards the end, he dies}}.

* ''[[Shakugan no Shana]]'' has this in Yuji. As a Torch, he's technically already dead, and, under ordinary circumstances, would inevitably be doomed to burn out and fade from existence. However, he's also a Mystes, and happens to have the artifact Reiji Maigo sealed within him, which replenishes his power of existence every midnight. As such, as long as he doesn't use up all of his existence in a day, he can lend his power to Shana, and, later, cast his own unrestricted spells, using his very existence.

** One occasion in the manga being so severe, Sailor Moon's ''entire body disintegrated completely'', she get better of course (because of the Galaxy Cauldron and the 'rebirth wave' she initiated), but damn.

* [[Magical Girl Lyrical Nanoha]] gives one of these to Nanoha in the third season. It's called the Blaster System and it boosts Nanoha's power and gives her a set of [[Attack Drone]]s that can cast her spells independently of her, for a potential boost of better than ''4x'' her already monstrous power level. The cost of this is placing an immense strain on Nanoha's body and dealing physical damage to herself and to [[Empathic Weapon|Raising Heart]]; when she used Blaster 3 in the climax of the third season, she lost 8% of her total magical power and had to spend the next few years on enforced vacation to recover it.

* ''[[Infinite Stratos]]'' does a technological example of this. IS battles end when one side's energy shields are depleted in order to avoid injury to the pilot - in fact, the unshielded IS instantly shuts down to prevent further fighting. The protagonist's most effective (and for a long while, only) attack is [[Laser Blade|Reiryaku Byakuya]] which saps his own shields to pierce through the enemy's and score an instant kill. The first time he used it, he had no idea how it worked and therefore lost the match because his shield zeroed out less than a second before the attack connected. After learning about it, [[Holding Back the Phlebotinum|he's understandably reluctant to use it against a manned IS ever again]].

** In fact, it was his sister who invented the attack and used it to win the IS world tournament.

* [[Toriko|Toriko's]] Autophagy. If he runs out of energy and needs more, his Gourmet Cells "eat" his own body to gain more power. If the Autophagy goes unchecked, Toriko's body will eat itself to death.

* In ''[[Pokémon Special]]'', though it's never explicitly stated, it's safe to assume Yellow's powers fall on the mild side of this trope as overusing her powers runs the risk of exhausting her and putting her into a deep sleep.

* [[Naruto]] has a few attacks like this, though any jutsu can kill the user if they're sufficiently exhausted of chakra, especially if it normally requires a large amount of chakra, [[Ass Pull|Sasuke notwithstanding]]. Pain/{{spoiler|Nagato}} used these almost exclusively; it's implied that this is the MO of most ninja from the clan he was born of, given their naturally long lifespans.

* In ''[[Magi: The Labyrinth of Magic|Magi Labyrinth of Magic]]'', using too much of your magoi is dangerous because of this. Magi, who can use the magoi and rukh outside of their bodies, aren't too bothered by this.
