During FB, the bosses will drop
molders. Molders are materials to make special gold glowing equipments, which are rare, powerful and also expensive. About how to distribute the molder if it drops, it's solely depends on the party members.
High level players will gain
exp and
reputation each time they help on FB bosses. (This is also why so many people offering help on FB quest with tablets)
For
19FB, there will be only one boss. Note that this FB is a must to do as it will reward you a lv20 blue glowing weapon which is powerful enough to use until level30. You will get the tablet and boss quest once you done with level19 cultivation.
