Let's Play Genius of Sappheiros (Extra) Part 36
Boss Time!
Existence Hater:
This boss has a main body and two mouths. Each of these parts have their resistances and immunities. Just know that the main body is resistant to just about everything except Mystic which it is neutral to. One mouth will do spells and heals including healing individual parts for 10k-20k health. The other mouth can buff its Physical Attack and focuses on offensive attacks. Each part can act up to two times per turn so it is possible for your party to be hit enough times for Alice to run out of blocks with Parrar (though it is unlikely).
Killing both Mouths causes the body to launch a super powerful attack that will most likely wipe the party unless Alice covers or you put up a barrier (it pierces defenses and ignores Reraise). After that, it will raise both Mouths. So kill only ONE Mouth. There is a small chance each turn that the body will ressurect that Mouth but you can just kill One of them again.
Once the boss is past the 25% point, it will use an attack that will do over 900 damage to everyone and pierce all resistances and prevent reraise. You will have to absorb it with Alice's cover. After it is used, the boss will not use it again unless it is healed back above 25% again. With Alice dead, you will have to either get her up again quickly or blitz the rest of the damage away.
