A dedicated F2P player in Zenless Zone Zero Version 2.0 can secure 70+ pulls across a 42-day patch — but only if every daily, weekly, and limited-time Polychrome source is tracked down with ruthless efficiency. Missing a single Hollow Zero bounty week quietly burns 160 Polychrome, a near-pull's worth that snowballs on a tight banner schedule. Mastering the maze of errand rewards and event calendars is mandatory for anyone chasing T0 meta agents like Yixuan.

Daily & Weekly Chores: Your Guaranteed Baseline

Start with the non-negotiable routine: every day, 60 Polychrome lands from completing Daily Errands in the Compendium (think coffee runs, Newsstand scratch-offs, and video store shifts). Howl’s Scratch Cards add an RNG layer, spiking up to 100 Polychrome on lucky rolls — veterans treat anything above 20 as bonus equity. Weekly, 60 Polychrome come from hitting 400 activity points (Weekly Ridu), backed by a fat 160 Polychrome per set from Hollow Zero Bounty Commissions. Miss both weekly layers and that's 220 Polychrome out — or over one full Signal Search lost in seven days. HoYoLAB check-ins are easy to overlook, but they hand out a silent ~60 Polychrome/month, best claimed early to avoid expired days.

Endgame Modes: Where the Heavy Pulls Come From

Every patch cycle, Shiyu Defense Critical Nodes explode with Polychrome — up to 720 per reset, hitting three times per patch for a total of 2,160. Clearing even mid-tier Critical floors far surpasses a week's worth of dailies in value. Deadly Assault missions and seasonal Combat Trials rotate in another 300–600 Polychrome; tracking these resets is crucial since their windows often overlap with event banners. Remember, only Critical Node resets are farmable—Stable Nodes and Disputed Nodes deliver one-off rewards, so new players should blitz these for a backlog windfall, not rely on them for regular income.

One-Time & Hidden Sources: The Backlog Goldmine

Digging into story chapters and side commissions nets straightforward gains: 30–60 Polychrome each, stacking fast during campaign progression. Hitting Inter-Knot Level milestones (20, 30, 40) through the Proxy Primer frontloads bulk pulls for fresh accounts — a true backstop for early pity building. Achievement hunting remains undervalued; with 5–20 Polychrome payouts spread across hundreds of entries (including specialized Godfinger Arcade feats), this route delivers dozens of silent Tapes over time. Trust-building with Agents, collecting HIA Medals via Officer MewMew, and exploring urban zones for district coins all add up — none massive individually, but collectively fueling banner chases.

Events, Codes & Maintenance Mail: The Patch Windfall

Each major version drop supplies a fixed 600 Polychrome through maintenance mail, paired with 300 Polychrome from three special program codes (redeem quickly at the official page before expiry). Flagship patch events typically yield ~1,200 Polychrome each; minor side events contribute ~400 Polychrome apiece. Occasional login events, like the All-New Program, pump in bulk resources — including up to 10 Encrypted Master Tapes (worth 1,600 Polychrome) just for consecutive logins. According to aggregated community reports, combining all event and challenge income with regular dailies yields well over 11,000 Polychrome (about 70+ pulls) per fully engaged F2P patch cycle.

When Free Isn't Enough: Efficient Top-Up With LootBar

Even for hyper-efficient grinders, acquiring a new Version 2.0 Rupture meta anchor often demands more than natural income provides. In these cases, veterans view Lootbar not as a shortcut, but as a controlled, discounted supplement when missing a T0 agent narrows to a handful of pulls as the banner expires. Typical LootBar Zenless listings offer 10–20% discounts versus official store rates, letting paid pulls stretch further without risking account safety on shady generators or sharing credentials. The core framing remains unchanged: every Polychrome is scored for maximum impact, with third-party top-ups serving only to bridge small, strategic gaps — never as a replacement for the F2P optimization grind.
