Mortal Shell - Dark Father The Unchained No Shell Boss Fight (NO DAMAGE)

This boss will be the most difficult as it has a variety of attacks and it takes the less amount damage out of all the bosses making you have to pay extra attention as any mistake could lead to a death and a long restart of this boss again.
You will want to have this boss up in your face for the most part of this. This is because if you hit the boss with 6 or 7 hits rapidly you can actually stun it and get 5 more extra hits in before it eithers retreats back makes waves, or attacks you. You will really want to capatalize on these to bring it's health down quick before it starts to summon enemies to attack you.
Once the bosses health gets low enough it will start to spawn enemies that will run at you and attack you. This is the hardest part as throughout this part you will either need to pay attention to 2 or 3 different types of attacks coming at you at once (more if the about 8 enemies are all near you trying to kill you). While enemies are running at you, if you don't deal with them quickly Dark Father can send a wave at you while rushing towards you, while the enemies are trying to attack you, and odds are you will die at this point by one of the three as it is near impossible to pay attention to it all.
You will want to dispath of these enemies quickly before dealing with dark father as they will be the bigger threat at this point. There is also a point where a whirlpool appears and the enemies get sucked into the whirlpool giving the dark father its health back.
