How do I get Faylen past bond level 4.9. When asking the fortune teller she says I need to increase my bond level with Nel but thats already at max.
To improve the bond between characters, Celica usually uses a special item in L.'s shop, joint walks to monsters, and some story quests with the characters indicated in the tip.
There are problems with this in early beta versions of 0.71. So if you are using a copy of the game from third-party sites, wait until the stable version of the game is released or try to work on other characters.
