Complete farming guide for Zhao’s ascension materials in Zenless Zone Zero with optimization strategies
Understanding Zhao’s Material Requirements
Zhao’s progression system in Zenless Zone Zero centers around two primary material categories: Defense Certification Seals and Freeze Chips. These resources directly complement her combat role as an Ice-element Defense specialist. Recent data mining by reputable sources like Hakush.in reveals the exact quantities needed for maximum ascension, allowing dedicated players to begin resource stockpiling immediately.
As a defensive ice-wielder, Zhao’s material requirements reflect her tank-oriented playstyle. The Certification Seals enhance her defensive capabilities while Freeze Chips amplify her elemental affinities. Understanding this synergy helps prioritize which materials to farm first based on your preferred build approach.
Maximizing Zhao’s combat effectiveness requires systematic investment in her ability upgrades. While the core boss materials for her signature skills remain undiscovered, planning around the known resource requirements ensures you’re prepared when that information becomes available.
Defense Certification Seal Farming
The Defense Drill challenge serves as your primary source for Basic, Advanced, and Defender Certification Seals. This combat simulation is accessible through the VR terminal situated inside the HIA Club headquarters. Each completion grants seal rewards based on performance, with higher difficulty settings providing better drop rates for advanced variants.
Optimization Tip: Focus on completing the Defense Drill during peak energy regeneration periods when your battery charge is naturally replenishing. This ensures you can run multiple attempts consecutively without waiting for charge recovery. The drop rates typically follow a tiered system where Basic Seals have 80% drop chance, Advanced Seals 45%, and Defender Seals around 15% on the highest difficulty.
Common Mistake: Many players waste attempts by not checking their current seal inventory before farming. Since these materials have stacking limits, exceeding your capacity results in lost resources. Always verify your storage space and consider ascending Zhao incrementally to avoid hitting material caps.
Freeze Chip Acquisition Methods
The Icing Test Combat Challenge provides all three tiers of Freeze Chips (Basic, Advanced, and Specialized) through wave-based combat scenarios. Accessible from the same HIA Club VR console used for Defense Drills, this activity consumes battery charge per attempt, making energy management crucial for efficient farming.
Strategic Approach: Since battery charge regenerates slowly over time, plan your Icing Test sessions around your daily play schedule. The most efficient method involves running these challenges when your charge is near maximum capacity, then switching to other activities while it regenerates. Specialized Freeze Chips have approximately a 20% drop rate on the highest difficulty setting.
Advanced Technique: Coordinate your team composition to include characters that boost drop rates or reduce battery consumption. Certain support agents provide passive benefits that can significantly improve your farming efficiency. Additionally, completing perfect runs (no damage taken) sometimes triggers bonus reward opportunities.
Hamster Cage Pass Obtainment
The Hamster Cage Pass represents the rarest material in Zhao’s upgrade path, primarily obtainable through the New Eridu City Fund battle pass system. Reaching level 30 guarantees one pass, with occasional additional copies appearing as event rewards during limited-time activities.
Battle Pass Strategy: Focus on completing daily and weekly missions that offer the highest battle pass experience points. The fastest route to level 30 typically takes 3-4 weeks of consistent play, but strategic focus on high-value missions can reduce this timeframe. Consider purchasing the premium battle pass if you want additional resources alongside the Hamster Cage Pass.
Event Opportunities: Limited-time events frequently offer Hamster Cage Passes as milestone rewards. Monitor the in-game event calendar and prioritize participating in these activities when available. Some events have provided duplicate passes, allowing players to stockpile this crucial resource for multiple character upgrades.
Advanced Farming Strategies
Resource Planning: Create a farming schedule that alternates between Defense Drills and Icing Tests based on your battery charge levels. Begin with Certification Seals since they don’t consume energy, then transition to Freeze Chips when your charge is full. This approach maximizes resource acquisition during extended play sessions.
Avoid These Pitfalls: Don’t neglect your team composition when farming – certain character synergies can reduce clear times by 30-40%. Never attempt high-difficulty challenges under-leveled, as failure still consumes attempt opportunities. Avoid spending premium currency on material refreshes unless you’re close to an important ascension threshold.
Time Management: The estimated total farming time for all of Zhao’s materials ranges from 15-25 hours depending on your efficiency and luck with drop rates. Breaking this into daily 1-2 hour sessions across 2-3 weeks makes the process manageable without burnout.
