In the rhythm-driven streets of New Eridu, proper gear is the difference between a glorious victory and a shameful beatdown. Drive Discs (once called Disc Drives) are the vinyl wizards that transform a decent Agent into a combat maestro. By 2026, the Bardic Needle music shop has become a sacred ground for Proxy theory-crafters — a place where Elfy, the cutest android DJ in the city, spins the gacha reels. Think of these discs as the HoYoverse cousin to Genshin Impact artifacts, but with more neon and a killer soundtrack. Each disc slots into a character’s build to boost base stats and, when paired correctly, unleash passive effects that can tip the scales of any Rally Commission.

Unlocking the Tuning System

A green-haired video store owner meets Elfy early on during story quests, and after some resource-gathering errands, the Rally Commissions system opens up. That’s when Elfy calls the player back to Sixth Street, flips the sign on Bardic Needle, and unveils the Tuning mechanic — a dedicated gacha for Drive Discs, completely separate from Signal Searches. Tuning costs five Plating Agents per pull (or fifty for a ten‑pull), and those Plating Agents drop from Rally Commissions like confetti at a punk concert.

The Best Drive Disc Sets for Meta-Chasers

Every Agent has six slots waiting for vinyl magic. Slap on two discs from the same set for one buff, or stack four for a juiced‑up passive. Here’s the 2026 guide to the top‑tier platters that still dominate the meta:

  • Polar Metal ❄️

2‑piece: +10% Ice DMG. 4‑piece: Basic Attack and Dash Attack DMG +20%. When any squad member triggers Freeze or Shatter, this bonus jumps another 20% for 12 seconds. Perfect for freeze‑happy comps that want to shatter opponents’ dreams.

  • Shockstar Disco ⚡

2‑piece: +6% Impact. 4‑piece: The main target of Basic Attacks, Dash Attacks, and Dodge Counters takes 20% more Daze. A stun‑specialist’s best friend, turning even a gentle tap into a one‑way ticket to Stagger Town.

  • Soul Rock 🛡️

2‑piece: +16% DEF. 4‑piece: After taking HP damage from an enemy hit, damage taken is reduced by 40% for 2.5s (15s cooldown). When a tank needs to eat a boss’s ultimate like it’s a mint candy.

  • Woodpecker Electro 🐦

2‑piece: +8% Crit Rate. 4‑piece: On a Crit triggered by Basic Attack, EX Special Attack, or Dodge Counter, gain a 9% ATK buff for 6s. The classic “more crits, more damage” loop that never goes out of style.

  • Chaotic Metal 💜

2‑piece: +10% Ether DMG. 4‑piece: Crit DMG +20%. When any party member triggers additional Corruption damage, the effect grows by an extra 5.5% for 8s, stacking up to six times and resetting the duration per new stack. Ether Agents crackle with stacking chaos.

  • Fanged Metal 🦷

2‑piece: +10% Physical DMG. 4‑piece: When an Assault is triggered on an enemy, the user deals 35% extra DMG to that target for 12s. For the bruisers who love to chew through health bars.

  • Freedom Blues 🎷

2‑piece: +30 Anomaly Proficiency. 4‑piece: Hitting an enemy with an EX Special Attack reduces their Anomaly Buildup RES to the user’s Attribute by 20% for 8s. No stacking with same‑attribute debuffs, but still a solo debuff king.

  • Hormone Punk 🔥

2‑piece: +10% ATK. 4‑piece: Upon entering combat or switching in for the first time, ATK soars by 25% for 10s with a 20s cooldown. Quick‑swap enthusiasts, this is your injector.

  • Inferno Metal 🔥🔥

2‑piece: +10% Fire DMG. 4‑piece: Hitting a Burning enemy cranks Crit Rate by 28% for 8s. Pyromaniacs rejoice — the hotter, the crittier.

  • Puffer Electro 🐡

2‑piece: +10% Penetration Ratio. 4‑piece: Ultimate DMG +20%. Launching an Ultimate also raises the user’s ATK by 15% for 12s. When every ultimate must pierce like a lightning bolt.

  • Swing Jazz 🎺

2‑piece: +20% Energy Regen. 4‑piece: A 15% DMG buff for all squad members for 12s after launching a Chain Attack or Ultimate. Doesn’t stack with same‑name passives, but the team‑wide boost is prime encore material.

  • Thunder Metal 🌩️

2‑piece: +10% Electric DMG. 4‑piece: Whenever any enemy on the field is Shocked, ATK gets a 28% lift. Electrifying everything in sight pays off.

Slot Stats and the RNG Substat Dance

Each Drive Disc occupies one of six slots. Slots 1–3 always roll the same base stats — HP, ATK, and DEF respectively — across all discs. Slots 4–6 feature variable main stats depending on the track’s identity: HP%, ATK%, DEF%, Pen Ratio, Elemental DMG Bonus — you name it. The real spice, however, comes from random substats. Two Woodpecker Electro discs in slot 6 can be as different as a ballad and a techno rave. An S‑rank Shockstar Disco might deliver Crit Rate, DEF, and ATK love, while a B‑rank version could just sprinkle a tiny HP dust. Leveling discs with Plating Agents amplifies all these numbers, so even a mediocre roll can turn into a banger with enough investment.

Equipping and Dismantling Your Vinyl Arsenal

Every Drive Disc is labeled with a slot number from 1 to 6. They can only be equipped to that specific slot, so mixing and matching across characters is a must. A squad member might rock Fanged Metal in slots 1, 2, 3, and 5, while Soul Rock fills 4 and 6 — but you can’t cram four copies of the same disc onto one Agent. That’s just musical chaos, not the good kind.

When inventory starts overflowing with B‑rank rejects, the dismantle option is a boon. Each recycled disc refunds one Plating Agent of its corresponding rank — a B‑rank disc gives a B‑rank Plating Agent. Remember: five Plating Agents buy one new Tuning pull. So, trashing five unwanted discs essentially re‑rolls the dice. It’s a minimalist’s recycling dream.

By 2026, the Drive Disc system has seen balance tweaks and new sets, but these core vinyls remain the backbone of any competitive Agent’s build. Stockpile Plating Agents, pray to the RNG gods, and may your substats always hit the high notes. Whether you’re shredding through Shiyu Defense or styling on Ethereals, the right tune makes all the difference.
