However, as Elder Master Xun said, this Four Symbols Formation is indeed too dangerous.
The line between right and wrong is very thin, and it's hard to control.
Borrowing the power of beasts and integrating it into oneself, using the body as the formation, is almost walking the edge between righteous and evil formations. One moment of inattention, and one might easily stumble and fall into the path of evil formations.
Moreover, Elder Master Xun also mentioned that beasts are close to monsters.
The beast patterns in the Four Symbols Formation can easily evolve into monster patterns.
Because superior "beast patterns" are hard to come by.
Divine beasts almost exist only in legends, exotic beasts are extremely rare, spirit beasts are not strong enough, and they are also very expensive.
These types of "beast patterns" are either scarce or too weak, making it almost impossible to meet the wide application of the Four Symbols Formation.
