[b]Energy Sap:[/b] (6 Energy)
Flare can concentrate and absorb heat from his surroundings causing him to gain the [i][b]Charging[/b][/i] status effect. While Flare is [i]Charging[/i] his defense is halved and he gains all the damage he takes or deals during this time is taken as charge. In addition he can not use basic attacks or abilities. Flare can consume this effect to deal damage equal to the current charge he has in addition to his ATK value.[/quote]
If you're going to limit Flare's use of his powers then I'd actually allow him to become [i][b]On Guard[/b][/i] (25% bonus to Defence), rather than weakening his Defence, since he'd be concentrating on absorbing energy. Also he'd be allowed to gain power from any damage received, whether it drains his Health or not, so his added Defence would allow him to draw in more power in one go without risking his Health too much.

[quote=@Eklispe]Also for Warming up, the reason I wrote it like was so that it applied to both energy expenditure as well as energy stealing effects.[/quote]
Okay, so any time Flare's Energy is reduced, either through use of abilities or enemy action, he gains the [i][b]Fired Up[/b][/i] status effect, giving him +1 Energy Regeneration and +1 Attack for two turns.

I'd limit this to only once per turn though, otherwise he'd very quickly become overpoweringly strong if facing multiple opponents, especially since his [i]Blazing Blood[/i] would already be bouncing damage back on anyone attacking him as well.
