This is mainly because the harder the spell, the more energy you need to pull it off, which is why certain spells that actually use basic traditional magic tend to cause noise bleeds, dizziness, fainting, and potentially death, depending on how powerful the witch is, in comparison to the complexity of the spell, or just how powerful the spell actually is.
這主要是因為越難的咒語需要越多的能量來完成,這就是為什麼某些使用基本傳統魔法的咒語往往會導致噪音大、頭暈、昏厥,甚至可能導致死亡,這取決於女巫的力量有多大,與咒語的複雜程度相比,或者僅僅是咒語的實際威力有多大。
