Does your grouping thing maintain the exact order things dropped in? I've noticed that things always drop their items in the same order (if the slot fills). If that's the case, then you can limit it down to:
Slot 1: Diorite
Slot 2: Mythril Ore
Slot 3: Golem shard
Slot 4: Beastman/Kindred Seal
Slot 5: Party 1 Light Crystal
Slot 6: Party 2 Light Crystal
Slot 7: Party 3 Light Crystal
Slot 8: Raxa (could also reversed with slot 7)
For reference, and a reason why I think "first two slots" may not be correct, Jailers have:
Slot 1: Virtue
Slot 2: OAT weapon
Slot 3: Torque
So if it was just "First two" it wouldn't affect the torques. Admittedly, I don't have any kind of a parse proving that TH affects torques, but it just seems unlikely that it doesn't.
