Compared to other overly self-assured Blue Dragons, Tassera possessed a degree of self-awareness, for a simple reason: she was a Storage Dragon and a mage. Spell models and mathematics were somewhat similar in nature; if you don't know something, you just don't know it. After failing enough times, anyone would naturally learn a sense of perspective.
Tassera understood her own abilities. Although she had mastered many spells, which made her a bit stronger than an average Blue Dragon, the difference wasn't dramatic. It's like how a mage skilled in numerous spells isn't necessarily more powerful than a clueless warrior.
It had to be said that spending excessive energy on spell mastery inevitably led to neglecting other skills, such as mobility, melee combat, and so on. In fact, even the powerful Chain Lightning wasn't as strong as a Blue Dragon casually using their Lightning Breath, and Autumn Dance Technique couldn't necessarily surpass Frightening Majesty in terms of control.
