hes 18 years old...<br/>i don't care how strong your magic is, using that level of power so young and untrained..its extreamley dangerous to both caster and surroundings. On this im speaking on magic in general as it is portrayed in countless games, forms, and beliefs.<br/>For mages like ours, who are all~18ish the closest thing that should get to a "supermode" should be something akin to a daily, like an "undying will" or "desperate power" [for mages, it would likely be something connected to will], and would only work on magics that are say, A rank or better.<br/><br/>As an example: say Destiny uses Pick a Card, and she used the effect to stunlock an enemy, visually represented by magical chains. in a moment of desperate power/unbreakable will, it would amlplify the damage and power of the hold. in another instance like a high cost spell i.e. destiny gate, or even a combination, you could cast those spells with no cost for the duration, but then very likely collapse at the end of the duration. for mages like ours, such power should be classified as high risk-high reward, or something like a saving throw.
