Generally speaking, the rule a wizard chooses to study when advancing to the Third Level is the most private and core secret of a wizard.
This concerns the future developmental direction of the wizard, their combat methods, and even the ceiling of their entire wizard career.
However, considering Viola's notoriously bad temperament, there's no need to ponder what rule she would choose.
Without a doubt, Viola chose the "Pain" Rule!
This rule in the Wizard World belongs to a relatively obscure branch.
It's quite peculiar. If used purely for combat, the direct enhancement to combat power isn't very large.
Especially if you encounter some battle-hardened, iron-willed creatures, the effect of this rule will be further weakened.
However, when facing certain special creatures, this rule has an exceptionally exaggerated auxiliary effect.
For example... the Living Ice and Flame Plane before us.
