It makes no difference, just add as much as you want. The higher the equipment level and level, the more external skill attacks will be added. (At the bottom line of equipment, there are figures such as equipment grade1060/1140/1240. The higher the level, the better the attribute. )

The equipment attributes of the same camp and the same profession are exactly the same, but the appearance colors are different, hero blue and villain red.

One party's attribute is better than the other, either the grade is higher than the opposite party or the equipment is strengthened, so the attribute is higher.
