How to Obtain
Drive Discs are farmed from Routine Cleanup at Bardic Needle (unlocked at Inter-Knot Lv. 20). Use Battery Charge to claim rewards. Higher difficulty stages drop S-rank discs more frequently. You can also craft specific sets at the Music Store using disc materials dismantled from unwanted discs.
How Drive Discs Work
Each agent can equip 6 Drive Discs across 6 slots. Equipping 2 discs from the same set activates the 2-Piece bonus. Equipping 4 discs from the same set activates the 4-Piece bonus (stacks with the 2-Piece effect). A common strategy is 4+2 (one full set + one 2pc from another) or 2+2+2 (three different 2pc bonuses).
