Four-level inscription

Yang Yan: spell attack +2.5, spell penetration+1.4.

Erosion: spell attack +0.9, spell penetration +3.8.

Instant: Maximum Health+13.5, Movement Speed +0.7%

Analysis: the inscription of level 4 is overused, because Zhuang Zhou is not a transshipment tank. If only the maximum life is added, Zhuang Zhou's output ability will be wasted, and the upper limit of life is not high. It is better to directly improve his output ability and ensure his advantage in individual combat. In addition, it can increase the considerable moving speed, ensure his flexibility, and let him do whatever he wants when fighting containment.
