In the bustling streets of New Eridu, Sixth Street's Bardic Needle stands as an indispensable hub for agents seeking power. This quirky music shop, nestled beside the Random Play video store, holds the key to unlocking the true potential of your squad through Drive Disc tuning. Operated by the knowledgeable NPC Elfy, the Bardic Needle transforms ordinary Master Copies into game-changing equipment. But how exactly does this neon-lit sanctuary revolutionize character progression in HoYoverse's acclaimed action RPG? As players dive deeper into Hollow exploration, understanding this mechanic becomes crucial for conquering endgame challenges. With Drive Discs directly impacting combat effectiveness, neglecting this system could leave your agents dangerously underpowered against evolving threats.
Core Mechanics of Drive Tuning
Upon unlocking the Bardic Needle, players discover its primary function: transforming Master Copies into Drive Discs through audio-based tuning. This process involves:
-
Resource Conversion: Spend Master Copies to generate randomized Drive Discs while unique soundtracks play
-
Targeted Farming: Use Track Settings to select specific Drive Disc Sets, guaranteeing 100% drop rates for desired items
-
Recycling System: Dismantle surplus discs into valuable materials - but beware, this action is irreversible!
Why risk dismantling recklessly? The shop's comprehensive Database archives every disc ever produced, allowing agents to review names, appearances, and effects before making permanent decisions. This becomes vital when optimizing builds for free starting characters like Billy or Nicole, who remain relevant throughout the campaign. Strategic dismantling converts unwanted B-Rank discs into resources for crafting elite S-Rank equipment.
Progressive Shop Upgrades
As your Inter-Knot Level grows through daily commissions and story progression, the Bardic Needle evolves through three distinct tiers:
| Level | Unlock Requirements | New Features |
|---|---|---|
| Level 1 | Initial Unlock | Basic Tuning (B/A-Rank Discs) |
| Level 2 | Mid-Game Progression | Intermediate Tuning (S-Rank) + Partition Selection |
| Level 3 | Endgame Preparation | Advanced Tuning + Main Stat Orientation |
Level 2 Breakthrough transforms gameplay with two revolutionary systems:
-
💿 Intermediate Tuning: Convert Noise Reduction Master Copies into powerful S-Rank discs
-
🔢 Partition Selection: Target specific equipment slots (1-6) during tuning, eliminating slot randomness
This upgrade solves the early-game frustration of getting disc #5 when your agent desperately needs #2. But what happens when you reach the pinnacle?
Level 3 Mastery introduces game-changing precision:
-
⚡ Advanced Tuning: Hi-Fi Master Copies guarantee S-Rank discs every single time
-
🎯 Main Stat Orientation: Hand-pick core attributes like ATK% or CRIT Rate before tuning
Strategic Optimization Techniques
With the Bardic Needle now fully operational in 2025's meta, top players employ these advanced tactics:
1. Resource Allocation Priority:
- Early Game: Spam Basic Tuning for A-Rank disc sets
- Mid Game: Hoard Noise Reduction Copies for Level 2 S-Rank spikes
- End Game: Reserve Hi-Fi Copies exclusively for perfect stat rolls
2. Partition Management:
- Always match disc numbers to agent slot weaknesses
- Example: Anomaly-build characters prioritize slot #4 discs
Considering the irreversible nature of dismantling, wise agents maintain a "disc library" in the Database before recycling. Why sacrifice a potential future meta-disc simply for immediate resources? The shop's evolution mirrors player progression - those who neglect Inter-Knot advancement will find themselves unable to craft the legendary Golden Ratio disc set dominating current speedrun leaderboards.
