This Guide is about making your Life easy as Possible and as Hard as Possible for the Boss ^^ We Only play, so we can't provide any Guides with her. With "we" i mean EisteeTowfu and myself ^^

Eternal Star:

• With Weakness (Choosen Character doesn't matter) If you have the Weakness, wich is the Weapon you get from Vile Visage, You Basicly Just Stay in Range and Spam it. Easy as that

• Without Weakness (Ace) Just Wait for him to Shit his first 3 Projectiles so he is in Range and you Dont have to Platform a lot in this fight and if he is in Range just do Damage, again Pretty Easy

Kur.

• With Weakness (again choosen Character doesn't matter) Just Stay put and Dodge his Attacks and you the Weapon you got from The Perforator, since it Throws his Square things back ( dont actually know the name of his Weapon) wich are dealing more damage than his Weakness it self

• Without Weakness (Ace) Now without his Weakness all you do is stay close and ready up for Melee attacks. Just deal Damage and D-Boost through his attacks

Shatterbreak

• With Weakness Before entering the Boss room make sure you Fully Charged the Weapon you got From Kur (yes you can charge this Weapon, it's the only One by the way) and only hit him with the Charged Kur Weapon he will be Dead in no time

• Without Weakness (Ace) Pretty Basic 20XX Combat Kill him as Fast as Possible otherwise you'll need to Play "Dodge the Ice Spike you don't see coming"

Twin Astrals

• With Weakness Just Kill him with the "Shotgun Ice" it will Freeze the red one but not the Blue one and for some Extra Damage use the Falling Platforms to hit him. The Falling Platforms are Dealing 50 DMG on hit

• Without Weakness (Ace) As usual stay close Deal Damage and of Course use the Falling Platforms to your Advantage

Rollster

• With Weakness With his Weakness you can Interupt his "Rage Phase" but basicly you'll need to deal most Damage through your Basic Attacks

• Without Weakness (Ace) Just Deal Damage, Easy as that xD

Death_Lotus

• With and Without Weakness Climb up and Use his Weakness or Basic Attacks as much as Possible while D-Boosting through his Turtle-Stance. DONT JUMP DOWN!

Vile Visage

• With Weakness Make Sure the Room is clear and then aim for his Weakspot with the Weapon you got from Death_Lotus

• Without Weakness (Ace) Deal damage as usual through your Basic Attacks and keep the room Clean from Enemys

Additional Side Note: You can also just walk Right into him if he is on low Health to Reach the Door Faster

The Perforator

• With Weakness You can Interrupt Phases with the Weapon to Prevent Damage, the Rest is Pretty Self Explaining by now :D

• Without Weakness (Ace) Optimal you want him to Stay Either in a Corner or on the Left/Right side to Prevent Damage whil Dealing Damage to him

Well guys thats it, if you think about it the Bosses are Actually not that hard if you have most of the Weaknesses, if not you'll need some good Dodging Skillz in the Later Stages
