Silver Hook and Snow Chiffon are playstyles that belong to the Sealing class.
Their single-target seal skills such as "Attack", skills like "含沙射影" (Sneak Attack) and "乾坤一掷" (Ultimate Throw) which are output/damage-dealing skills, are all relatively powerful skills. I will explain them one by one below.
Let me share my experience playing YG, from the old agent's second test to the experience server and now the current closed beta. I have always played this faction, so I have a fairly good understanding of it.
For arena battles, guild wars, quests, monster grinding, clearing maps, events, a Sealing class character is always the preferred choice and holds a very important position in Meng Gu.
Note: YG = Hook, TM = Tang Sect
