Tang Shaoyang got a lot of knowledge about the support class from Arina, Selena, Kang Xue, and Lunea. He did not know that they had such a big variety of supporting skills. There was also an individual buff and an area buff that affected people in a specific area.
The common was to increase the magic power or destructive power. Arina and Selena had an area of time healing. Kang Xue and Lunea had a skill that increased magic power, an area skill. Lunea even had a skill that could make a player double-cast the spell. If he shot a fireball, it would become two fireballs. It would be big for a big spell, like the meteors he met on the 22nd floor.
