To maximize your combat efficiency and output massive Stun and Anomaly multipliers in HoYoverse's action RPG, you must prioritize unlocking Core Passive upgrades, Assist Follow-Up skills, and ultimate-enhancing nodes for your primary DPS and Stun agents during the early-game progression. Wasting valuable Dennies and Buster Chips on basic attack string upgrades before securing utility-focused skill nodes will severely bottleneck your account during mid-game Hollow Zero runs and Shiyu Defense floors.
Understanding the Skill Priority Hierarchy
When investing scarce materials into your roster, not all talents are created equal. The combat loop of Zenless Zone Zero relies heavily on rapid Daze accumulation, quick assists, and flawless dodge counters. Pumping resources into standard normal attacks yields diminishing returns early on, whereas unlocking utility and combo-extending passives radically alters your damage per second (DPS) ceiling.
For players diving into deep end-game mechanics, managing your resources is just as crucial as handling your gear progression, much like managing your setup in games featured in our V Rising gear score guide. By focusing on mechanical upgrades that boost interaction between character switches, you lay a solid foundation for flawless combat execution.
Best Core Passive Skills to Unlock First
Core Passives are absolute game-changers because they unlock unique character mechanics that define how an agent operates on the battlefield. For instance, unlocking the Core Passive for a Stun agent like Lycaon or Anby directly increases the Daze multiplier inflicted on enemies, shortening the time required to trigger a Daze state.
- Stun Agents (Anby, Lycaon): Prioritize Core Passive enhancements up to Level C immediately. This scales up your Daze damage significantly against elite foes.
- Attack Agents (Ellen, Zhu Yuan, Corin): Focus on skills that boost critical rate or elemental damage multipliers upon hitting stunned targets.
- Support Agents (Nicole, Lucy): Unlock energy regeneration and buff-duration nodes to maintain permanent uptime on defense-reduction debuffs.
Neglecting Core Passives in favor of raw attack stat boosts will leave your teams dealing significantly lower burst damage during stun windows. Make sure to check out our deep dives into character synergies similar to the optimization strategies found in our Final Fantasy 7 Rebirth party builds guide to ensure your team compositions make the most of these passive buffs.
Special Attacks and Chain Attack Enhancements
Once your core passives are online, your next priority should be your Special Attacks and Chain Attacks. In Zenless Zone Zero, Ex-Special Attacks are your primary source of invulnerability frames (i-frames) and elemental anomaly buildup. Upgrading these skills increases their damage scaling percentages without always increasing their energy cost, making them exceptionally cost-efficient.
Why Chain Attacks Dominate Combat
Chain Attacks trigger whenever an enemy is launched or stunned, pulling multiple characters into a sequenced flurry of heavy strikes. Unlocking nodes that augment Chain Attack damage multipliers ensures that every single switch-in hits like a truck. If you enjoy fast-paced action combat mechanics where timing and rapid transitions dictate success, you might also appreciate the high-octane pacing discussed in our Warzone Mobile character unlock guide.
Optimal Skill Progression for Top Tier Agents
To give you a concrete roadmap, here is the exact skill upgrade order you should follow for S-Tier characters dominating the current meta:
- Core Passive (Level A to C): Unlocks foundational team utility and character-specific gimmicks.
- Ex-Special Attack: Scales up your primary damage dealer's main burst tool and elemental application.
- Chain Attack / Ultimate: Boosts heavy burst windows against stunned bosses in Shiyu Defense.
- Assist Attacks: Improves defensive switching, perfect dodge follow-ups, and evasive assists.
- Basic Attack: Leave this for last unless your character is a hyper-carry on-field driver like Nekomata.

Dodge Counters and Quick Assist Investments
Many players overlook Dodge Counters and Quick Assists in favor of flashy offensive skills, but mastering these defensive mechanics is vital for survival in high-level Hollow exploration and Hollow Zero modifier runs. Upgrading your Dodge Counter increases the retaliation damage dealt right after a Perfect Dodge, turning defensive maneuvers into aggressive counter-attacks.
Furthermore, Quick Assists allow you to seamlessly transition between agents when an enemy initiates an unblockable red flash attack. Upgrading these assist nodes ensures that your incoming character enters the fray with temporary damage reduction or immediate energy charge bonuses. Similar tactical positioning and squad management principles apply when tackling tough cooperative challenges like those found in our collection of top free co-op games on Steam Deck.
Managing Materials and Avoiding Resource Traps
Hollow investigator supply crates and Denny caches are notoriously tight during the first thirty levels of your account. Do not spread your upgrade chips evenly across all characters. Concentrate 80% of your farmed materials into your primary hyper-carry DPS and their designated Stun partner. Leaving your support agents at lower skill levels temporarily is entirely acceptable as long as their core support passive threshold is met.
Keep a close eye on weekly boss drop materials required for higher-tier skill enhancements. Planning your upgrades ahead of time ensures you never waste precious Battery Charge on inefficient domain runs. By sticking to this prioritized skill unlock guide, you will breeze through story chapters and claim top ranks in Shiyu Defense with absolute ease.
