Most Proxies don't hit the Inter-Knot Level 30–40 wall because the game is difficult — they hit it because they spent their first 20 hours skipping Daily Errands, overflowing Battery Charge, and pulling into banners without tracking soft pity. Every one of those mistakes is measurable lost progress. This guide covers every core system — progression gates, combat mechanics, leveling priorities, and pull economy — structured so you reach Shiyu Defense without repeating the community's most documented errors.

Understanding ZZZ's Core Progression Systems

Your Inter-Knot Level (IKL) gates everything: story chapters, character level caps, and Shiyu Defense difficulty tiers all unlock at specific IKL milestones. The Reputation Level system compounds this — Proxy Rank Up trials at IKL 20, 30, and 40 raise World Level and loot quality, making them mandatory checkpoints, not optional content. Skipping even one delays your farming efficiency for entire weeks.

Battery Charge functions as both a material-farming currency and a direct XP source. Spending 1 Battery Charge yields 10 Inter-Knot XP, which means your daily natural regen of 240 Battery represents 2,400 XP sitting idle if you don't spend it. Veterans treat Battery overflow as a direct IKL loss — the cap is 240, and anything generated above it disappears.

How to Level Up Fast: Prioritizing XP Sources

Ranking activities by yield prevents misallocation:

Prioritize the Main Story first — it delivers the largest single XP chunks available. Never let Battery cap at 240; spend it daily at the HIA Club on ascension materials. Daily Errands take under 5 minutes and deliver a guaranteed 600 XP — missing one day is a straight deficit with no recovery mechanism. The Proxy Handbook functions identically to Genshin Impact's Adventurer's Handbook: completing early objectives front-loads XP and funds further pulls. For players willing to invest, the Inter-Knot Membership at $4.99/month delivers 3,000 Polychromes over 30 days (300 instant + 90 daily), which supplements daily XP gains and maintains pull cadence simultaneously.

Combat Fundamentals: The Stun Meta and Chain Attacks

Every team composition in ZZZ is built around one loop: fill the Daze bar to 100%, trigger the Stun, execute the high-damage window. Stunners like Anby, Lycaon, and Qingyi fill the Daze bar fastest and belong in virtually every early-game roster. During the Stun window, cycle through your team's Chain Attacks to concentrate burst damage — this is where most of your actual kill speed comes from.

Disorder damage is the secondary damage event new players most commonly overlook. Applying a second Anomaly effect while the first is still active on an enemy triggers a Disorder burst — one of the highest single-hit damage events accessible without a complete roster. Pair an Anomaly character with a Stunner and you access both high-value windows simultaneously. For gear, prioritize Drive Disc set bonuses over raw stats until IKL 40; a 4-piece set bonus on mediocre substats outperforms a mixed stat spread on premium pieces at this stage.

Gacha Mechanics: Understanding Pulls, Pity, and Polychromes

Monochromes purchased from the shop convert to Polychromes at a 1:1 rate. Polychromes then purchase Master Tapes and Encrypted Master Tapes. Understanding this chain matters because new players frequently confuse the two currencies and miscount their pull budget. Soft pity begins around pulls 74–75 on S-Rank banners, meaning pull rates increase significantly in that range. Hard pity guarantees an S-Rank at 90 pulls. Pulling without tracking your current pity count is the single most-reported way new Proxies waste premium currency — maintain a manual count or use a community pity tracker.

Free Polychrome sources — Daily Errands, Proxy Handbook completions, event rewards — provide a steady drip that reduces spending pressure. Time-limited banners create real urgency for targeted top-ups, but only when your pity count makes the math favorable.

Topping Up Polychromes: Official Channels and Trusted Platforms

Monochrome tiers run from $0.99 to $99.99, with first-purchase bonuses doubling the amount on every tier. The in-game Signal Shop and the official zzz top up center at sdk.hoyoverse.com both support the full tier range — the web portal is the practical choice for players topping up outside the mobile client or on behalf of another account. Platform stores (Google Play, App Store, PS5 PSN Wallet) support the same tiers through their respective payment systems.

Unauthorized third-party sites consistently produce account bans — the community documents this repeatedly. Authorized alternatives include CodaShop (Southeast Asia, supports GrabPay and GCash) and Razer Gold (global). For players evaluating community-referenced options, LootBar top up is a platform that appears in pricing discussions. Regardless of channel, HoYoverse enforces a strict no-refund policy: a chargeback through your bank results in a negative balance and an immediate account ban until the debt is resolved. The Inter-Knot Membership at $4.99 remains the highest per-dollar Polychrome value for daily-active players — 3,000 Polychromes over 30 days against a $4.99 outlay outperforms every single lump-sum tier on a value-per-dollar basis.
