Steps:
In area B, you kill 5 enemies & 10 enemies via certain methods to get Chest #B3 and Chest B4.
In area B, you kill 3 enemies via certain methods to get Casket #B1.

What it should be based on trends throughout the rest of the zone:
In area B, you kill 3 enemies & 6 enemies via certain methods to get Chest #B3 and Chest B4.
In area B, you kill 5 enemies via certain methods to get Casket #B1.

Why this is a bug:
In area A B C & D, you do something related to doors to get Chest #[ ]1.
In area A B C & D, you do something related to Devices to get Chest #[ ]2.
In area A C & D, you kill 3 enemies & 6 enemies via certain methods to get Chest #[ ]3 and Chest #[ ]4.
In area A & C, you kill 5 enemies via certain methods to get Casket #[ ]1.
In area D, you kill 6 enemies, one of each job to get Casket #D1. This makes sense as there are 6 different jobs, and positioning of them in zone is basically screaming for us to kill one of each.
