So I finished the game at 59/60.
Bessie and Ray were 60, the MC was 59, and dinged 60 after
.
The Eris fights were so much easier then Eden, although for some reason Ray showed no heath, just the MC's tank it up buff, and every time I used Cura on her the health just vanished. Same for Ray's mana pool, it stayed right around 500ish, if I used Ray's spirit control, the extra vanished right after her turn was up. Same for a hi-ether, it bumped Ray up to 9999 then dropped right back in the 500's.
No problem with the MC, one shot from Ray's spirit leech and he hit max MP, ditto with Bessie and her Osmosis shot reclaiming her used MP.
