What is the dark attribute of the seal and what is its function?

At present, the seal has two dark attributes: 1. Powerful obstacle pet: Enhance the powerful obstacle to pets, similar to the green attributes of weapons "Powerful Forgetting" and "Powerful Freezing", but only effective for pets, not monsters and characters. 2. Pursuit rate: There is a certain chance to pursue fixed damage during physical attack. The damage value is related to the role level and has nothing to do with other attributes such as equipment.
