On October 6, 2026, Roxy and Promeia banners are live in Version 3.2 Phase II of Zenless Zone Zero, while Phoenix and Severian are scheduled to drop on October 21 in V3.3. Every Battery Charge and Dennie spent during this window either accelerates a roster or becomes dead weight. The classic IK 45+ trap — one capped DPS, an empty wallet, and half-farmed Drive Discs — continues to catch new Proxies every banner cycle. This guide presents a guaranteed-upgrade-first framework that helps players build one functional team without hitting a stamina wall.

⚡ The Universal Upgrade Priority Order

Guaranteed upgrades always outperform RNG. Agent levels scale every multiplier that skills and discs touch; disc substats are a lottery that punishes early investment. The following hierarchy applies to any new S-Rank, from Roxy to Phoenix:

This is the Zenless Zone Zero upgrade priority checklist that applies equally to a fresh M0W0 Roxy and a day-one Phoenix pull.

🎯 Agent, W-Engine, and Skill Breakpoints

The main DPS should be pushed to Level 60 immediately — that is non-negotiable for Shiyu Defense scaling. Stun and Support Agents can remain at 50–55 until the DPS is finished; the material savings are significant when Level 50→60 costs roughly 800k Dennies per Agent. Certification Seals (Attack, Stun, Anomaly types) are farmed from Combat Simulation using daily Battery Charge.

For W-Engines, the DPS engine should reach 60 while Stun or Support engines stop at 50 — the Impact secondary stat at 50 is sufficient until the carries are complete. Without a signature S-Rank, the Box Galaxy gadget store crafts A-Rank W-Engines that hold a player over without spending a single Polychrome.

Skill investment follows role logic, not gut instinct:

• Attack Agents (Severian, Ellen): Core Passive → Basic Attack → EX Special → Ultimate

• Stun Agents (Roxy, Lycaon): Core Passive → EX Special Attack (Daze) → Assist/Dodge Counter

• Anomaly Agents (Promeia, Jane Doe): Core Passive → Special Attack → Basic Attack

Hamster Cage Passes should be saved exclusively for Level 11–12 upgrades on the strongest S-Rank. Spending them on a 4-star support is a tourist mistake.

🔋 Drive Discs and Battery Charge Discipline

Disc farming before IK 45 is the single biggest stamina trap in New Eridu. The math never favors early RNG when a guaranteed skill level delivers consistent multiplier gains.

• IK 1–35: Zero Battery Charge on disc farming. Use story drops and Music Store pieces; verify only the main stat (ATK% on slots 4, 5, 6).

• IK 35–45: Farm enough for a 4-piece set bonus — Woodpecker Electro for DPS archetypes — and level discs to +9 or +12.

• IK 45+: Chase S-Rank discs with CRIT Rate/CRIT DMG or Anomaly Proficiency substats depending on role.

Daily resource discipline keeps the engine running:

• Spend Battery Charge on Combat Simulation every day; the cap is 240 and overflow is pure waste.

• Drink Coffee once per day for +60 Battery Charge and a drop rate buff.

• Never convert Polychromes into Battery Charge — those are banner funds only.

• Spend Boopons on the Bangboo banner; Windy-Boo provides direct synergy with Roxy's Wind team.

🌀 Version 3.2 Builds and V3.3 Prep

Roxy (Wind Stun) is the IK 45+ unlock for Wind-weak boss content. Her Core Passive should be leveled first — it activates the "Gale Daze" application that makes her kit functional. Skill priority: EX Special → Assist Counter for maximum Daze output.

Promeia (Ice Anomaly) lives and dies by Anomaly Proficiency. An Anomaly Proficiency main stat on Drive Disc Slot 4 must be locked in before touching anything else, then her Special Attack skill should be elevated. Without that slot-4 foundation, her Anomaly damage remains sub-par regardless of level.

For V3.3 preparation, players should start stockpiling Fire-type tactical chips and Anomaly certification seals for Phoenix now — farming them after the banner flips means competing with a new content drop for the same Battery Charge. Pre-farm Wind Attack materials for Severian in parallel. The October 21 launch date and exact banner details should be confirmed on the official site before committing pulls. Proxies weighing Inter-Knot Membership or bulk pull options can compare available packages through reputable retailers ahead of the V3.3 window.
