V stage, also known as the near-rule level.
For every pet beast, the V stage skill proficiency level represents a watershed.
Even the most superficial use of Rule Power holds an overwhelming advantage over conventional supernatural forces.
If one wishes to bring their core technique up to V stage, then a comprehension of the Rule Power of all their attributes is necessary.
This leads to a new problem.
It is that the more attributes a pet beast has, the more difficult it becomes to elevate its skills from IV stage to V stage.
It's like others only need to finish homework for one subject while you have to complete several.
With the same strength, pet beasts with multiple attributes tend to be stronger than those with a single attribute, perhaps that's the price they pay.
If a pet beast has only one attribute, then it only needs to comprehend the Rule Power of that attribute to push its core technique to V stage.
