Why don't we post our save files for people who either are too lazy or tried everything and can't do it.
I'll start by uploading my Good ending file
That has the good ending, 2 zhelms, level 4 final weapons, Solo Zeru, Solo Antlan, Sup~heal Serene, and mob Royke. All strikes unlocked for Zeru, all 'sevens' unlocked for Antlan. All party+reg heals on Serene, and Everything except Ragnorak, Strafe and arrow rain on Royke
Put in the FinalStory folder. Don't forgot to move your save files somewhere else in case you want them again because if you replace em they're gone for good.
P.S. If this is disobeying some rule do not hesitate to delete.
Zeru's note
(Yes it is link is removed, no sharing save files in public in the forums but I won't mind if you send save files by PM's or other methods.)
