Hogwarts Master of Color

The wizard's emotion is the core key to the effectiveness of the spell, which directly determines the power, accuracy and even effect variation of the spell. Positive emotions, such as pure happiness, can empower the Divine Protection Charm, extreme love can form a strong protective barrier, and negative emotions, such as murderous intent, can strengthen the Avada Kedavra Curse. When a little wizard is able to see emotions, he can even touch and control them. So can he become a god to wizards.
