Early stage: Sun Bin's main role is to assist teammates and ensure their safety. Therefore, he should swim more to support teammates from all walks, and he can release his second skill to cover his teammates' escape.
Mid-late stage: In a large-scale group battle, Sun Bin can control the enemy with big moves, disrupt the formation of the enemy, and connect a skill to stun the enemy, so as to facilitate teammates to cause higher damage to the enemy and assist teammates to kill the enemy.
The difficulty of Sun Bin's operation is mainly that the release of the first and third skills needs to predict the enemy's position, which may make some budding new players inaccurate in judging the position of skill release, so that Sun Bin's role in the battle is not high, but these are only subjective factors, which can be improved through more practice.
Frost staves increase Sun Bin's spell attack damage, and passive frosting can slow down the skill from hitting the enemy. The Book of the Sage increases a lot of spell damage and makes Sun Bin damage per second more impressive.
The frozen heart increases Sun Bin's physical defense, makes Sun Bin more viable, reduces skill CD, increases maximum mana, and makes Sun Bin's skill release less restricted. Passive ice heart can also reduce the attack speed of nearby enemies. The guards' glory increases the movement speed, which makes Sun Bin move more flexibly. The passive legion can improve the attack damage of the surrounding friendly forces.
Sun Bin mainly relies on skills to control the enemy, which consumes a lot of blue, but Sun Bin is not the main output, so he can't grab the blue buff of his teammates. Therefore, the first piece of equipment is recommended for the Holy Grail, which can not only restore a small amount of mana to Sun Bin, but also reduce the skill CD. Cool boots can improve the moving speed and reduce the skill cooling time, which can make Sun Bin's skill release more flexible.
