ZZZ Drive Disc Salvage — Which Discs to Keep or Dismantle | Zenless Zone Zero

Salvaging (dismantling) clears your storage and turns spare discs into materials. But don't rush it while you're still short on gear: every disc-tuning guide assumes you already own enough S-Rank discs to kit out your main team. If you're new and still have empty slots, keep using A-Rank discs and hold off on dismantling A-Ranks.

Once your storage fills up and your core team is mostly on S-Rank discs, that's the time to cull: keep the good ones, salvage the rest. Golden rule — don't hoard "just in case"; keep only discs that serve a character you're building now or soon.

Dismantling returns two material types depending on the disc's rarity:

• S-Rank disc → HI-FI Master Copy + Crystallization Additive.
• A-Rank disc → Noise Reduction Master Copy + Plasticizer Additive.

Master Copies let you exchange for a disc of the set you want at the shop — targeted farming instead of pure RNG. Additives are disc upgrade/tuning materials. That's why dismantling beats feeding discs as raw EXP fodder: fodder only gives EXP, while dismantling gives upgrade material AND Master Copies.

Each Agent wears 6 Drive Discs. Slots 1, 2, 3 have fixed main stats (flat HP, ATK, DEF) — no main-stat filtering needed there. The value lives in slots 4, 5, 6, where the main stat is randomized:

• Slot 4: 6 options — HP%, ATK%, DEF%, CRIT Rate, CRIT DMG, Anomaly Proficiency.
• Slot 5: 9 options — HP%, ATK%, DEF%, PEN Ratio, and the 5 elemental DMG bonuses.
• Slot 6: 6 options — HP%, ATK%, DEF%, Anomaly Proficiency, Impact, Energy Regen.

Whether a disc is a keeper mostly comes down to whether its slot 4/5/6 main stat fits the character's role.

Keep a disc when its slot 4/5/6 main stat matches the role:

• DPS (Attack / on-field Anomaly): slot 4 CRIT Rate/CRIT DMG/ATK%; slot 5 the character's matching elemental DMG or PEN; slot 6 ATK% (Anomaly units may want Anomaly Proficiency).
• Stun: prioritize slot 6 Impact, slot 4/5 ATK%.
• Support/Defense that scales on HP or DEF: here HP%/DEF% is actually the correct main stat — e.g. HP% for healers, DEF% for Ben.

Beyond the main stat, keep discs from the 2-piece or 4-piece set the character needs, with at least 2 useful substats. Not sure if a disc is good? Drop its stats into gamevika's Drive Disc score checker to compare fast before deciding keep or scrap.

Salvage freely when a disc shows any of these (for ATK-scaling characters, i.e. most DPS):

• Slot 4/5/6 main stat is HP% or DEF% but the character doesn't scale on HP/DEF → dismantle. (Exception: if you run an HP/DEF-scaler like Ben, keep those specific ones.)
• Slot 6 rolls a wrong-element DMG bonus versus the disc/character — e.g. a Fire-set disc granting a non-Fire DMG bonus → dismantle.
• Duplicate set + duplicate main stat but weaker substats than the one you already use → keep the single best, salvage the rest.

This is exactly the filter the JP community uses: open disc storage → Filter → select slots 4-6 and HP% main stat to quickly round up the scrap pile.

Each disc has up to 4 substats. Every time it reaches Lv 3, 6, 9, 12, 15, the game upgrades a substat: if it has fewer than 4 lines it adds a new one, once at 4 it reinforces an existing line. S-Rank discs go to Lv 15 (five upgrades if they start with 4 substats); A-Rank stops at Lv 12.

Resource-saving tip: don't max every disc. Level to Lv 9 or Lv 12, then check — if by then it has fewer than 2 useful substats (CRIT, ATK%, PEN, Anomaly Proficiency…), salvage it rather than pour in more materials. Only fully invest in discs that roll multiple correct lines.

Since Version 2.5, ZZZ has Drive Disc Auto-Dismantle: preset which disc rarities get salvaged the moment you pick them up, keeping storage from overflowing. Rest easy: it only applies to A-Rank (and B-Rank) discs and never auto-scraps S-Rank discs, so new players won't lose a good disc by accident. Dismantling also runs in batches (up to 300 discs at once), clearing storage far faster.

The clean loop: farm discs in the defense mode → use Filter to gather junk (slots 4-6 with HP% main stat, or wrong element) → batch-dismantle → spend Master Copies on the right set at the shop. To confirm what main stat each character wants, check the disc score checker; and if you plan to pull for more discs, read the pity system to budget your resources first.
