Ended up using my spark that I was keeping up for the summer in winter units here because Ferry is one of my favorite characters (ended up getting her on the 30th 10 roll so I sparked Cain D:). I suppose I'll have to pass and skip the summer banner unless the free rolls are willing.
Ferry is the new dark grand character and the first grand dark character in the main gala. She seems to be build completely around supporting Hades Stamina builds and she has strong synergies with Clarisse Valentine.
Her kit is
1) Ougi gives Party wide Dark ATK + DA (same as Ultima's ougi)
2) First skill inflicts DEF/ATK down (25%) and a special debuff that grants 10% echo to all party members until active. The buff is active until the enemy uses a special move in which case it disappears trigger a 1 mil plain damage nuke
3) Second skill does 1500 party wide heal, party wide revitalize, party wide 20% charge bar boost.
4) Third skill gives a special buff to a dark character giving various buffs (DA, TA, Hostility, Charge attack dmg, charge attack dmg cap, charge bar gain is boosted, resurrect if killed) . If the turn is 10+ she also gives TRIPLE STRIKE.
5) Passive reducing all incoming light and dark damage for all allies.
Her kit as you can see screams "hades stamina" and I don't see her working too well in a magna enmity grid.
Her weapon is also a nice Sentence skill so I'm likely going to use my next damascus to uncap that one and see how it goes with my grid in the coming weeks/months.
