Where to find B’baba
Since Faye scurries off, the soldiers will tell you that only one person can find her. It’s none other than B’baba, who’s located in Daphan Village, which is east of the city of Hishahn. Upon entering the village, check the house in the upper-left corner and talk to the B’baba. The fortune teller has already prepared for your arrival, and she readily joins your forces.
You should now be able to construct the Divination Parlor in Eiyuden Chronicle: Hundred Heroes. It only requires 1,600 Headquarters Funds. Once built, you’ll see the stall in the room to the right of the Drafting Studio on the first floor (i.e. where you unlock buildings and upgrades).
