Nice to know about the potentially upcoming changes. I still have much to do before I reach the current end of the game.
Currently I'm trying to get the succubus TF and I'm also trying to get every Succubus Behavior Point. But theoretically there is one point where I don't know how we should get them:
We can get one succubus point by seducing the Obviously-High Magical Girl in the Raiding Yoshida's room quest. But to seduce her, we still should not have access to Yoshida's room.
To get the succubus TF, we need 4 out of 5 items, but 2 of them are not accessible if we wait to seduce the magical girl.
Thats why:
1. The Silk Robe lays in Yoshida's room. If we got access to that room over another way than we are no longer able to seduce that magical girl. So this item is definitely out of question.
2. Zeligniew's toys are only accessible, if we are on the Operation fluffy kitten quest. But if we have this quest active then the Yoshida's raiding room quest will automatically end, since you don't need to raid her room while she have every core with her in the dungeon.
So in my point of view it is impossible to seduce that Obviously-High Magical Girl right now. Or did I miss something again?
