Currently, it's very frustrating to get the 6* set reward in the Lost Map.
1) You need rng to get the map fragments.
2) You need rng for the chest to appear.
3) You need rng for the piece you want to drop.
I hope the devs can split the reward dungeon to 2 for each map, one dungeon dropping the accessory and one dungeon dropping the vanity.
This way, the players can aim for a specific piece.
