Thank you so much for help. What i mean in the question 2, is that i think there is there is some kind of event in which several girls are involved: Rokkas, the girl trapped in the body of the orc who for some reason will now be in the body of a puppet now, 2 of the girls with wings from when we recruited jyla , the fairy of mist city, and I think a giant.
my question is, how does that happen, because within the game data, there is an image of them as a group, and another where they turn into stone
It has been mentioned above but I will remention+ explain how you get the stone and group images in game.
Rokkas is unlocked by Phantom express library observing her book and the druid book (next to each other), then using Gorgon braid to free her, after facing her in Tabneth Arena (Post red tome) you can get her to oneshot the demon queen (one of 2 final bosses).
For Knightess (Puppet knight) use punish options and either turn Orc into statue or Remove and discard Collar, other options lock you out last I remember)
For Avian Support (If memory serves they are 2 council members), You find them outside Tabneth (One looking for the other, who has been turned into puppet, find them in hidden alcove to top right of map (near Samaloth Puppeteer enemy spawn region). Reunite them then interact once in Sea Market area to unlock. *THIS REQUIRES YOU SPARE THEM AFTER BLUE TOME FIGHT*
For Fairy* Just mercy her after City of Mist Boss then talk to her once in Forest Spring (Never done this beyond a one off as the spring is an absolute pain in the ass to navigate to)
Giant is Ex captain of Spellball team of New Rokkas, After defeating her spare her, when she challenges you again spare Her again. She will flee to Druid hut in Woods. Talk to her their to get her support.
Regarding the Images of them together (as flesh and blood and Petrified) these are unlocked via different methods. I think the Character assembled Picture is seen if you got support from ALL the character prior to fighting demon queen, they show up at that point and give the option to help you ruin the bosses day (Rokkas can straightup OHKO the boss so is VERY much worth recruiting given Nuan/your best unit is kinda buggered that fight... Same with Sinian aswell**)
The Stone Screen If memory serves is what happens if you take the demonic pact the demon queen offers prior to and partway into the fight. If you accept you turn on your would be allies and petrify them. (May be wrong on certain parts as forgot parts since preffer fighting Hargrave/alternative final boss... she is MUCH easier)
*I Hate that bloody fairy puppeteer fight... the number of times I needed to restart that fight after they got lucky with Ignis Fire or Soul freeze is just... and don't get me started on the invinciblity till x turns passes part, I wasted so much time whaling on the bloody puppet with element infused attacks before I found THAT tidbit out...) I enjoyed Bad ending her...
**As Nuan has access to your heaviest hitting multistrike attacks... (Sable hits hard but is more Rng based to Nuans agility based=Multistrike attacks), Nuans BEST attack (that doesn't take forever building TP for) is Flame strike (High level Nuan with Flamestrike setup can oneshot most bosses nosweat)... which is nosold by demonic enemies absorbing Fire and Dark to heal... this makes Nuan less effective as she cant straightup DPS the enemy to death in 1/2 turns (She can 3 turn Hargrave if properly setup).
Also Sinian has over HALF her spells as fire based... so is also completely fucked against Demonic Spire/Demon Queen. (If you have to sacrifice a unit for Corrupted status effect in journal,sinian is ironically best unit (Commoner is best soulgem item fodder).
Hargave is easiest final Boss as a result (As you can straightup one shot her vanguards with flamestrike if Nuan is maxed out, and basically make this battle a complete joke with Akagiri/Level 10 Ultimate skill. Just save Tp to 100, use cruelty twice, then watch as you instagibb the final boss force).
