First have to fight Venom Daoist from Pool of Shattered Jade Shrine. Later from the Temple Entrance Shrine, Venom Daoist is in a new area where you fight him again and get to interact with a wall to enter the secret area of Purple Cloud Mountain. This boss is at the end of the secret area.
@@austinjones9276 Chapter 4, yes, after you beat Violet Spider and get lifted to a new area. It's off to a far path going right. There are two paths, one leads to Fungiwoman and one leads to Venom Daoist 2 (only there if you fought him earlier in Chapter 4).
