This limited-time content focuses on combat puzzles and tactical team decisions—making it critical for those seeking progression without overspending.

Context: Event Timing & Precedents

The Simulation Training event falls between flagship banner phases, offering a focused resource-gathering window for players not chasing the current limited block. By gating access with a moderate Inter-Knot Level, HoYoverse continues to nudge players towards consistent progression.

The event structure mirrors recent limited-time combat activities seen in prior patches, offering escalating challenges tailored for both new and mid-game Proxies. The inclusion of trial Agents—especially featured characters like Seed and Orphie & Magus—gives all participants a risk-free opportunity to test unique combat styles that may sway future gacha decisions.

Key Mechanics & Tips

  • Stage-Specific Gear: Every stage offers bespoke Gear items that grant offensive buffs or tactical advantages. These can drastically alter an Agent’s role or survivability. Practice optimizing Gear selection before committing to high-difficulty clears.
  • Trial Versions: Notable for F2P and new Proxies—using Seed and Orphie & Magus as trials lets you preview their full kit in real combat, helping inform both team strategy and gacha pull plans. Consider documenting your impressions for comparison with their standard banner performances.

Events & Reward Highlights

With event-locked missions tracked by completion, players can expect the following major rewards:

  • Polychromes: Gacha currency, ideal for stockpiling ahead of rumored banners (unconfirmed—subject to change).
  • Boopons: Key for acquiring Agents through standard pulls or event rolls (see EarlyGG currency guide for usage).
  • Upgrade Materials: These expedite Agent ascension and skill levelling—a crucial resource for both meta and favorite teams.

Completion Tips: Prioritize daily mission clears to ensure no stage is missed due to time gating. Several materials require perfect clears or challenge objectives—check requirements before entering high-level stages.

Should You Participate? F2P and Low-Spend Guidance

  • F2P/Low-Spend:
    • The event costs only time and in-game effort, not premium currency—making it highly recommended for netting Polychromes and Boopons without monetary investment.
    • Even if current banners aren’t your priority, these rewards accrue value for future top-tier Agents or reruns.
  • Optimizing Rewards:
    • Review trial Agent kits carefully—early mastery can inform efficient build investments.
    • Prioritize "Showdown" stage attempts for maximum resource payout.
  • Pity and Banner Overlaps:
    • Event rewards alone won’t push most players to a 10-pull, but they supplement banner grinding without extra cost. No current overlaps with competitive, high-rate banners have been stated in official channels.

Preparation Checklist

  • Hit Inter-Knot Level 15 early to prevent time-loss at event start.
  • Clear "Mole in the Hole (I)" in Agent Story mode.
  • Prepare a flexible team—rotation and projectile management mechanics favor adaptable squads.
  • Monitor EarlyGG’s ZZZ event hub for last-minute strategy updates and meta shifts.

What to Watch Next

With limited-time events like Simulation Training, Zenless Zone Zero continues to incentivize multi-Agent investment and tactical experimentation. Expect player discussion to gravitate towards stage solution sharing and optimal trial Agent builds, especially on community servers and social media. Looking ahead, resource catch-up events of this kind may shape the free-to-play pacing around larger patch releases or upcoming reruns (unconfirmed for November banners—subject to change).
