You must finish Erza quest, then she will give you the ability to f**k them xD.
Hmmm….. I’m pretty sure I did? Went into the dungeon found whatever she was looking for, unlocked DP scene…. No dialogue available with her and no guidance from Naamu either so I’m guessing somewhere along the line the questline got broken maybe and skipped over setting this particular flag? Hmmmm….
If you go to the floor 28 and Melkor kicked you out. Erza will tell you to rest, then skip one day. Go to her and give Erza one XL Wisdom Potion, and she will tell you to look 3 pieces: The first one is from Solan (buy it for 2000 gold), the second is from Ginny (this one is sealed), and the third one is from Luna (she asks you to find it. It's behind the couch). Then go back to her and her quest will be finish, now you can see a new scene and the new ability.
