How to beat Erlang, the Sacred Divinity in Black Myth: Wukong
In his first form, confuse him with clones instead of transforming

A lot of many

Train mitigation

Beating the four heavenly kings
You’re facing four enemies at once, so stay on your guard
Once you get Erlang’s health down to zero, he’ll call in backup in the form of the Four Heavenly Kings. The four kings represent the four cardinal directions, and are called Duōwén Tiānwáng (North King), Chíguó Tiān (East King), Guǎngmù Tiānwáng (West King), and Zēngzhǎng Tiānwáng (South King). Each of the kings will attack you at once, but thankfully, their attacks are somewhat simple. If you still find yourself struggling, try swapping out your armor set for something stronger.
Presumably in order not to overwhelm the player in the fight, each of the four kings features a simplified version of movesets you’ve already seen in the game. The best strategy is to fight one king at a time, dodging the other’s attacks while you whittle one down. Use light attacks to fill your focus meter, and unleash a heavy attack when you get the chance.
