Sorry English is not my language, I use google translator, I hope it will be clear.
The first boss goes through block and counterattack. The main thing is not to get hit when he swings his girlfriend's body. Then the same through the block, counterattack, and spinning (defense + attack). The second boss also through the block and counterattack, the complexity in the second phase, there you need to break the sword after twice blocking it with a shield, it is difficult to hit it hitbox small. Third boss (Goddess) [try to keep shield until the third phase]- first phase hit her on her legs, and run away from the trident and do not get under her boots when she starts stomping (shield block practically does not work). The second phase is relatively easy, block the blow when she crawls on her belly and swings her sword, then don't miss the moment when you need to use the special attack near the altar to set the spear on fire. when it hits the milk, destroy the sperm, then you'll get to the Goddess again. Have time to kill her before she starts moving otherwise you will have to dive into the milk again. The third phase - through block, spinning and counterattack to kill her. The fourth boss - Dragon, how to pass I do not know.... Stuck on him.
