To tell the truth, it is best to keep the shoulder, but the landlord said that it must not be changed, so there is only the head. Regardless of the legs, just look at the attributes, and the head and hands are still left. All realms are stronger than Yang Yan's hand, because it increases the hit. If you play enough, all realms are not as good as Yang Yan. If the landlord changes hands, then the hit is definitely not enough (SW graduation), so only the head is left. Because of T6 head bump, the necklace can choose to bring a natural pity brooch. The T6 head is also a symbol of SS, which can be kept.
As for the argument that there is no need to keep 4T6, completely ignore it, fight a battle, let him look at the battle statistics himself, and burn out the proportion in the total damage.
