while on mission list (and map view) there is a flag on left side, click there to unfold the list of kidnapped girls, count that those dungeons are difficult on new kidnapped girls, and it makes easier the more corrupted they are, so depending on your current teams, can try a rescue or notHow does one attempt to rescue "kidnapped" party/guild members ?
In-game, when a party member "goes-down" . . . your told you can always rescue them later .
Bull-Crap !!! I have yet to get any opportunity, to attempt to do that, None, Nada. Zip !
Is it really a game feature ? , or , something that hasn't been implemented as yet ?
if use to have girls on that state, check them often as its a way to get some items as reward that unlike normal drops from chests are curse free, so even with a novice team can end a dungeon, not by clearing all, but explore locate girl and rescue her, and if possible try to sneak past to the end to get the reward, if you see that last part as impossible can also retreat with your girl back but no extra reward
is not uncommon though at least to me, that on some rescue mission i got the girl back but got one or more captured instead, when that happen, the rescued girl can take the place of one of the fighters on your team, but caution, as if she is not yet equiped with three cursed items should be naked from main clothes so vulnerable to equip attacks from enemies, if she is equiped with 3 or more can still be vulnerable to equip attack but also has a cursed class
