💿 Drive Disc Stats Guide — Main Stats, Substats & Optimization
🛒 Optimize your setup with our Recommended Gaming Gear
📋 Drive Disc System Overview
Drive Discs are ZZZ's equipment system — equivalent to artifacts/relics in other gacha games. Each agent equips 6 Drive Discs organized into 3 pairs (2pc × 3) or a 4pc set + 2pc set. Discs have a main stat (fixed by slot), level (1-15), and up to 4 substats. Each disc costs progressively more to upgrade, making efficient resource allocation critical. Drive Discs are farmed at the Music Store using Battery (stamina), starting from IK 15.
🔑 Key Stat Categories
- Offensive: ATK%, Crit Rate, Crit DMG, DMG Bonus%, PEN Ratio
- Anomaly: Anomaly Proficiency, Anomaly Mastery
- Stun: Impact
- Support: Energy Regen, HP%, DEF%
- Universal: ATK, HP, DEF (flat stats — generally worse than % versions)
🎯 Slot-by-Slot Main Stats
Each disc slot has a fixed main stat type. You cannot change the main stat category for a given slot, but you can choose which specific stat to use within the available options.
| Slot | Available Main Stats | Best For | Notes |
|---|---|---|---|
| 1 | HP (fixed) | All agents | Always HP — no choice. Substats matter here. |
| 2 | ATK (fixed) | All agents | Always ATK — no choice. Prioritize ATK% substats. |
| 3 | DEF (fixed) | All agents | Always DEF. Provides survivability. Substats only. |
| 4 | Crit Rate / Crit DMG / ATK% / Anomaly Proficiency / HP% | DPS: Crit Rate or Crit DMG Anomaly: Anomaly Proficiency | Most impactful slot. Crit agents want ~1:2 CR:CD ratio. Anomaly agents want 350+ AP. |
| 5 | ATK% / PEN% / DMG Bonus% / DEF% / HP% | DPS: DMG Bonus% or ATK% Anomaly: ATK% or PEN% | DMG Bonus% (Elemental) is usually 5-8% better than ATK% for DPS agents when both are available. |
| 6 | ATK% / Impact% / Energy Regen / Anomaly Mastery / HP% | DPS: ATK% Stunner: Impact% Support: Energy Regen | Role-defining slot. Your stunner MUST have Impact% here. Supports want Energy Regen. |
💡 Main Stat Priority Rule: Correct main stats > wrong main stats with good substats. Always use a disc with the right main stat even if its substats are terrible — the main stat contributes 80% of a disc's total stat value.

🎲 Substats: What to Keep & What to Trash
Substats are the main source of late-game power: only ~15% of an agent's final stat sheet comes from main stats at max level, with substats making up the rest. Each disc can have 3-4 substats initially, gaining +1 substat every 3 levels (Lv. 3, 6, 9, 12, 15).
Substat Priority by Role
| Priority | Attack DPS | Anomaly Agent | Stunner | Support |
|---|---|---|---|---|
| Top Tier | Crit Rate, Crit DMG, ATK% | Anomaly Proficiency, ATK%, PEN | Impact, ATK% | Energy Regen, ATK% |
| Good | PEN, ATK (flat) | Anomaly Mastery, PEN% | Energy Regen, Crit Rate | HP%, ATK (flat) |
| Niche | Energy Regen | Energy Regen | ATK (flat), HP% | DEF% |
| Low Value | HP%, DEF%, HP/DEF flat | Crit Rate, Crit DMG | DEF%, HP (flat) | Crit stats, DMG Bonus% |
🔥 Substats Rule of Thumb: For Attack DPS, a disc with 3 useful substats is a "keeper." 4 useful substats is "god roll." For Anomaly agents, Anomaly Proficiency substats are so valuable that a disc with 2 AP rolls + 1 ATK% roll is already very good.
💰 Farming Efficiency & Resource Management
When to Farm
- IK 15-34: Do NOT farm Drive Discs. Focus on character ascension and skill materials. Use the free 5★ discs from story rewards.
- IK 35-44: Start farming the Music Store (Rift 5). Only farm for correct main stats — don't chase substats yet.
- IK 45+: Rift 6 unlocked. Begin substat optimization. Use the self-modeling resin (artifact transmuter) on Slot 4 for the hardest-to-find main stat.
Recycling System
Don't discard unwanted discs directly — recycle them at Scott's Outpost for valuable materials:
- Gold discs → 10 Gold per piece → Exchange for self-modeling resins or tuning calibrators
- Purple discs → 3 Gold per piece → Not worth farming but worth recycling if you have extras
- Blue/green discs → Vendor for 10 Dennies each → Minimal value
Daily Farming Route
- Use your first 60 Battery daily on the Music Store (Drive Discs)
- Use 30-60 Battery on character ascension materials (VR Device)
- Reserve remaining Battery for skill materials (VR Device)
- Spend recharge Battery (from coffee, events, etc.) on whatever you need most
