ZZZ Auto Chess Co-Op: Amillion F2P Shiyu S+ 90k Guide

Introduction to ZZZ's Auto Chess Co-Op Mechanics

Ever jumped into a co-op lobby and watched your team steamroll bosses without lifting a finger? That's the magic of ZZZ's Auto Chess PvE mode. You've got four key roles: DPS for raw damage output, Break for shields and defense, Support for buffs and heals, and Daze Master for those clutch stuns. Aim for one of each to balance things out—unlocks Elite lobbies after level 10, and trust me, it makes clears buttery smooth.

Here's how it kicks off:

1. Host picks the stage.
2. Everyone grabs agents that fit their role.
3. Hit confirm with a quick chat ping.

Those temporary cards and emblems? Game-changers for tweaking stats on the fly. Need a progression boost? Buy Zenless Zone Zero premium currency safely through BitTopup—instant delivery, killer prices, full security, and rave reviews from the community.

Core Mechanics: Controlling the Board

Positioning is everything. Cards and emblems pump up stats and trigger co-op bonuses, while quick chats, revives, and resonator badges layer on extra perks across all eight mission types. (Pro tip from the edit desk: I've seen lobbies wipe because someone forgot to front-load the Daze Master—don't be that guy.)

Quick mission rundown:

• Annihilation: Just wipe out the enemies.
• Elite: Unlocks post-level 10, wave after wave.
• Timed: Double speed multipliers if you hustle.
• Elemental: Play to resistances.
• Alarm: Solve the puzzles fast.
• Treasure: Hunt those randomized chests.
• Final Battle: Boss loot heaven.

To dominate:

1. Slot emblems smart—Daze Master up front.
2. Revive any downed agents ASAP.
3. Badge up for those sweet stat bumps.

Daze mechanics hit hard on story bosses: 37.5% buildup (30 DEF, 200% Stun DMG, 12s stun, -20% Physical RES, freeze immune). Brutal, right?

Best Bangboo Teams for Co-Op

Amillion steals the show for F2P Physical squads—pair it with Billy (DPS), Anby (Break/Daze), and Piper (Support). Cunning Hare CRIT synergy? That's 20-30% output spikes. Second boss (60 DEF, 25% buildup, -20% Ether/Physical RES, +20% Fire RES, 12s stun) practically begs for Ether/Physical + Amillion. (Editor’s take: Tested this in 20+ runs; it's the meta king until 2.5 drops.)

Run it like this:

1. Stack that Physical team.
2. Trigger Chain Attacks off daze procs.
3. Grind Boopons in Shiyu.

Top F2P Bangboo Alternatives

Amillion reigns supreme for Billy/Anby/Piper Physical (hello, Cunning Hare bonuses), powering S-rank Shiyu clears. Boopon farming? 80 pulls beat pre-2.5 W-Engines, straight to Awakening Currency.

Budget setups:

• Physical core: Billy/Anby/Piper + Amillion.
• Swap Piper for Elemental Domains if needed.

Nail it step-by-step:

1. Snag Amillion from free events.
2. Level with Research Items across 20 investigation tiers.
3. Test in Arcade multiplayer.

Shiyu breakdown: 5 stages, 60k points max each, S+ demands all S-ranks for 90k+ total. Shop jumps Polychrome from 720 to 780.

Maximizing Rewards: The Loot Breakdown

Chase these: Research Items, Gadgets, Clues/Chests, Polychrome, Awakening Currency, Merits. Shiyu S+ showers Polychrome, Boopons, weapons, materials. Treasure Hunt? Randomized jackpots. Shop sells Awakened Potentials (Polychrome 720→780).

Max it out:

1. Clear all 8 stages for Research Items.
2. Nail Shiyu stage 5 S+ (3 rooms, 5 Critical Nodes, 3 teams).
3. Stockpile for v2.5 Phase 1 (Dec 30–Jan 21).

Critical Nodes want S/SS agents; cap speed at 60k per stage. Data shows it's worth the grind.

Strategic Tips for Co-Op Success

Spam quick chat for revives and badges. Physical teams feast on that -20% RES debuff. Boss counters: Story loves 37.5% buildup Physical/Daze; second thrives on 25% Ether/Physical.

Execute:

1. Host from Arcade: Main Story to Prologue Intermission, Sixth Street right of the video store.

2. Multiplayer: Arcade → Multiplayer → Invite (+) → Match.
3. Lean on Daze Masters for 12s crowd control.

Cross-play's live; server levels gate Final Battle. Smooth.
