๐ Overview
Ascension materials are the core resources you need to level up your agents in Zenless Zone Zero. Every character requires a combination of Element Chips, Enemy Drop Materials, and Weekly Boss Drops to ascend past level 20, 40, 50, and 60 breakpoints. Skill upgrades also consume vast quantities of these materials, making efficient farming essential for endgame progression.
This guide provides a complete reference for every material type, every character's material requirements organized by faction, and the most stamina-efficient farming strategies. Whether you are pre-farming for an upcoming banner or trying to max your current carries, this is your one-stop resource for all ascension-related questions.
๐ก Key Insight: Pre-farming materials before a character's banner releases can save you up to two weeks of dedicated farming. Always check what materials a new character needs and start farming at least 2-3 weeks before their release!
โก Stamina Budget: A single S-rank character needs approximately 8,000-9,000 total stamina to reach max level with all skills at level 12. Plan your resources accordingly and focus on one team at a time.
๐ฆ Material Types
All ascension and skill materials in ZZZ fall into five broad categories. Understanding what each is used for is the first step to efficient farming.
| Category | Materials | Used For | Primary Source | Rarity |
|---|---|---|---|---|
| Basic Chip | Basic Chip | Ascension 0โ1 (Level 1-20) | Enemy drops, Combat Simulation, Shop | โ |
| Advanced Chip | Advanced Chip | Ascension 1โ2 (Level 20-40) | Combat Simulation (lvl 45+), Elite enemies | โ โ |
| Specialized Chip | Specialized Chip | Ascension 2โ3, 3โ4 (Level 40-60) | Combat Simulation (lvl 60+), Notorious Hunt | โ โ โ |
| Element Crystals | Fire/Ice/Electric/Ether/Physical Crystal | Ascension at every tier (element-specific) | Notorious Hunt (element boss), Combat Simulation | โ โ / โ โ โ |
| Weekly Boss Materials | Unique boss-specific items (see table) | Core Skill upgrades (outer skill ring) | Notorious Hunt (3 attempts/week) | โ โ โ |
| Skill Upgrade Materials | Blade/Shield/Gem/Star tokens (GreenโBlueโPurple) | Skill levels 2โ12 for each skill | Skill Material Domain (day-rotated) | โ โ โ โ โ โ โ โ |
| Enemy Drop Items | Faction-specific drops (see below) | Ascension + skill upgrades | Open world enemies, Hollow Zero | โ โ โ โ โ โ โ โ |
๐ฆ Rarity Breakdown: Chip Materials
| Tier | Material Name | Rarity Stars | Used At Character Level | Quantity Needed (per char) |
|---|---|---|---|---|
| Tier 1 | Basic Chip | โ | 1-20 Ascension | 4 |
| Tier 2 | Advanced Chip | โ โ | 20-40 Ascension | 12 |
| Tier 3 | Specialized Chip | โ โ โ | 40-60 Ascension | 15 |
๐ฅโ๏ธโก๐๐ฅ Element Chips
Element chips are required for ascension at every breakpoint. Each character uses chips matching their attribute (Fire, Ice, Electric, Ether, or Physical). These chips drop from Notorious Hunts (elemental world bosses) and Combat Simulation domains.
| Element | Basic Chip | Advanced Chip | Specialized Chip | Boss Source | Domain Source |
|---|---|---|---|---|---|
| ๐ฅ Fire | Basic Fire Chip | Advanced Fire Chip | Specialized Fire Chip | Pompey / Doomsday Butcher | Combat Simulation โ Flame Training |
| โ๏ธ Ice | Basic Ice Chip | Advanced Ice Chip | Specialized Ice Chip | The Hati / Frost Domain | Combat Simulation โ Frost Training |
| โก Electric | Basic Electric Chip | Advanced Electric Chip | Specialized Electric Chip | Corruption Complex | Combat Simulation โ Volt Training |
| ๐ Ether | Basic Ether Chip | Advanced Ether Chip | Specialized Ether Chip | Rainmaker God | Combat Simulation โ Aether Training |
| ๐ฅ Physical | Basic Physical Chip | Advanced Physical Chip | Specialized Physical Chip | Dead End Butcher | Combat Simulation โ Brawl Training |
๐ฏ Farming Tip: Always run the highest-difficulty Combat Simulation level you can clear. Higher difficulties guarantee Advanced and Specialized chip drops with much better stamina-to-material ratios. At Inter-Knot level 50+, the level 60 domain guarantees 2 Specialized chips per 60 stamina run.
๐ Total Element Chips Per Character
To fully ascend a character from level 1 to 60, you need the following total of element chips:
| Element Chip Type | Level 1-20 | Level 20-40 | Level 40-50 | Level 50-60 | Total |
|---|---|---|---|---|---|
| Basic Element Chip | 4 | โ | โ | โ | 4 |
| Advanced Element Chip | โ | 12 | โ | โ | 12 |
| Specialized Element Chip | โ | โ | 10 | 15 | 25 |
๐พ Enemy Drops & Farming Routes
Enemy drop materials are the most commonly needed ascension resources. Each faction of enemies drops a specific material line with three rarity tiers. You can farm these from open-world enemies, Commission missions, and Hollow Zero without spending stamina on domains.
| Enemy Faction | Basic Drop | Advanced Drop | Specialized Drop | Best Farming Route |
|---|---|---|---|---|
| Thugs (Red Fang Gang, etc.) | Basic Thug Badge | Advanced Thug Badge | Specialized Thug Insignia | Lumina Square โ back alleys; Combat Simulation (Thug Training) |
| Ethereal (Hollow enemies) | Basic Ethereal Core | Advanced Ethereal Core | Specialized Ethereal Nucleus | Hollow Zero โ any corruption zone; Combat Simulation (Ethereal Suppression) |
| Sacrifice (cultist enemies) | Basic Sacrifice Emblem | Advanced Sacrifice Emblem | Specialized Sacrifice Crest | Hollow Zero โ ritual grounds; Combat Simulation (Sacrifice Domain) |
| Construction Machines (Belobog enemies) | Basic Machine Gear | Advanced Machine Gear | Specialized Machine Core | Construction site areas (Outskirts); Combat Simulation (Machine Training) |
| Rebel Soldiers (Obol Squad enemies) | Basic Military Insignia | Advanced Military Insignia | Specialized Military Medal | Military restricted zones; Combat Simulation (Rebel Suppression) |
๐ฐ Stamina-Free Farming: Open-world enemies respawn daily and do NOT require battery charge. Spend 10-15 minutes each day farming the specific enemy faction you need. Use Hollow Zero Investigation Points for material boxes to fill gaps in your inventory.
๐ Open-World Enemy Route Recommendations
| Material Needed | Recommended Route | Enemies | ~Time Investment |
|---|---|---|---|
| Thug drops | Lumina Square โ Port Area โ Back Alley | Red Fang thugs, street gang | 8-10 min |
| Ethereal drops | Hollow Zero โ Outskirts Lv.1-3 | Ethereal spawns, corrupted zones | 10-15 min per run |
| Sacrifice drops | Hollow Zero โ Ritual Grounds Corridor | Sacrifice cultists, altar guardians | 10-15 min per run |
| Machine drops | Construction Site โ Outer Ring | Construction mechs, automated units | 8-10 min |
| Military drops | Restricted Zone A โ Checkpoint B | Rebel soldiers, security mechs | 10-12 min |
๐๏ธ Weekly Boss Materials
Weekly boss materials are used for Core Skill upgrades (the outermost skill enhancement ring on a character's skill screen). These are the scarcest materials in the game because Notorious Hunts are limited to 3 attempts per week at 60 stamina each. Each character needs 9 total of their corresponding weekly boss material to fully max their Core Skill to level 12.
| Weekly Boss | Drops | Used By Factions | Notes |
|---|---|---|---|
| Dead End Butcher | Dead End Butcher's Sinful Relic | Cunning Hares, Anby, Billy, Nicole, Nekomiya | Physical domain boss; drops Physical ascension chips |
| The Hati | The Hati's Frozen Core | Section 6, Soukaku, Yanagi, Harumasa; Ice-aligned agents | Frost domain boss; drops Ice ascension chips |
| Marionette | Marionette's Orchestrating Component | Victoria Housekeeping, Ellen Joe, Lycaon, Corin, Rina | Elegant domain boss; drops Defense-oriented chips |
| Corruption Complex | Corruption Complex's Cleaned Unit | Belobog Heavy Industries, Grace, Koleda, Anton, Ben; Electric agents | Electric domain boss; drops Electric ascension chips |
| Rainmaker God | Rainmaker God's Blessing | Zhu Yuan, Qingyi, Seth, Jane Doe; NEPS agents | Ether domain boss; drops Ether ascension chips |
| Pompey | Pompey's Fury Emblem | Sons of Calydon, Caesar, Burnice, Lucy, Piper | Fire domain boss; drops Fire ascension chips |
| Doomsday / Bringer | Doomsday's Ominous Star | Obol Squad, Soldier 11, Trigger | Mixed domain boss; drops varied ascension chips |
โฐ Weekly Boss Strategy: Always use all 3 Notorious Hunt attempts before Sunday weekly reset. If you are building a specific character, focus their boss exclusively โ the 3-attempt-per-week cap means you need 3 full weeks to get the 9 materials needed for max Core Skill on a single S-rank character.
๐ Weekly Boss Material Requirements
| Core Skill Level | Weekly Boss Mats Needed | Cumulative Total | Weeks of Farming |
|---|---|---|---|
| Level A โ B | 1 | 1 | 1 (3 attempts) |
| Level B โ C | 2 | 3 | 1 (3 attempts) |
| Level C โ D | 3 | 6 | 2 (6 attempts) |
| Level D โ E | 3 | 9 | 3 (9 attempts) |

โก Farming Tips & Stamina Efficiency
๐ฅ General Priorities
| Priority | Activity | Stamina Cost | Reason |
|---|---|---|---|
| ๐ฅ 1st | Notorious Hunt (weekly boss) | 60 ร 3 per week | Limited attempts โ never let these cap. Core Skill is essential for every character. |
| ๐ฅ 2nd | Daily Commissions + 60 stamina spend | 60+ | 60 Polychromes per day from the daily reward track. |
| ๐ฅ 3rd | Skill Material Domains (correct day) | 60-120 | Day-rotated โ farm on the right day to avoid wasted stamina. |
| 4th | Character EXP / Dennies | 60-120 | Always useful; never wasted. Bottleneck resources for most players. |
| 5th | Drive Disc farming | 60 (custom) | Endgame sink โ only once characters are leveled and skilled. |
| 6th | W-Engine Ascension | 60-120 | Low priority unless building a specific W-Engine for a main carry. |
๐ Weekly Skill Material Rotation
| Day | Skill Material Available | Best Activities |
|---|---|---|
| Monday | Basic Attack (Blade) Materials | Blade farming + Weekly boss |
| Tuesday | Dodge (Shield) Materials | Shield farming + Enemy route farming |
| Wednesday | EX Special (Gem) Materials | Gem farming + Drive Discs |
| Thursday | Ultimate (Star) Materials | Star farming + Element Chip domains |
| Friday | All Skill Materials Open | Catch-up on any missing skill mats |
| Saturday | All Skill Materials Open | Same as Friday โ fill gaps |
| Sunday | All Drop Types Open | Best day โ farm anything. Prioritize W-Engine / Drive Discs |
๐ฐ Stamina Efficiency Rankings

| Hollow Zero Runs | 0 (Free) | Investigation Points + shop currency | โญโญโญโญโญ (Free) |
๐ Best Free Stamina Activities: Hollow Zero weekly clear gives 80 Polychromes + shop currency for Master Tapes. Open-world enemy routes give ascension materials without spending battery charge. Always do both every week before spending stamina on enemy drop domains.
๐ง The 80/20 Stamina Rule: Early game (IK 1-40): 80% EXP/Dennies, 20% skill materials. Mid-game (IK 40-55): 50% skill materials, 30% EXP/Dennies, 20% W-Engine. Endgame (IK 55+): 50% Drive Discs, 30% skill materials, 20% everything else. Adjust based on your current bottlenecks!
๐ฎ Pre-Farming Checklist
Before pulling for a new S-rank character, use this checklist to prepare enough materials to get them to at least level 50 with level 8 skills:
| Material | Quantity Needed (to Lv.50) | Quantity Needed (to Lv.60 max) | ~Stamina Cost |
|---|---|---|---|
| Basic Element Chip | 4 | 4 | Free / from daily farming |
| Advanced Element Chip | 12 | 12 | ~120 stamina |
| Specialized Element Chip | 10 | 25 | ~300-750 stamina |
| Basic Enemy Drop | 4 | 4 | Free (open world) |
| Advanced Enemy Drop | 12 | 12 | Free or ~60 stamina |
| Specialized Enemy Drop | 10 | 15 | ~120-200 stamina |
| Weekly Boss Material | 2 | 9 | 1-3 weeks of weekly farming |
| Skill Materials (all skills) | ~60 Green / ~40 Blue / ~20 Purple | ~120 Green / ~80 Blue / ~50 Purple | ~1,000-2,000 stamina |
| Dennies | ~500,000 | ~1,500,000+ | ~500-1,500 stamina |
| EXP Materials | ~20 Purple Logs | ~60 Purple Logs | ~600-1,800 stamina |
โ Frequently Asked Questions
Approximately 29-37 days of dedicated stamina usage (240 stamina/day). This includes character ascension, skill materials, weekly boss farming (3 weeks minimum for Core Skill), W-Engine leveling, and Dennies. Focus on getting your main team functional (level 55, skills level 8-10) before maxing any single character.
Absolutely yes. Save all your battery reserves for double-drop events (usually one per patch). Using 30 batteries during a double-drop week effectively doubles your stamina output for that week. This is roughly 2x more efficient than using batteries outside of events. If you urgently need materials for a Shiyu Defense clear, using 1-2 batteries is fine, but avoid burning your entire reserve.
For free (no stamina): run open-world enemy routes daily. Each route takes 8-15 minutes and gives you enough Basic/Advanced materials for regular ascensions. For stamina efficiency: run the highest Combat Simulation level you can clear. The level 60+ domain guarantees Advanced and Specialized materials. Never run lower-level domains โ the material-to-stamina ratio is significantly worse.
Yes. ZZZ has a material synthesis system in the item menu. You can combine 3 Basic chips to make 1 Advanced chip, and 3 Advanced chips to make 1 Specialized chip. This uses no stamina but does consume Dennies. It's generally not recommended to synthesize lower-tier materials unless you're in a rush โ it's more efficient to farm the correct tier directly. However, if you have hundreds of Basic chips from open-world farming, synthesis is a perfectly valid way to get value from them.
If you know a character's element (from leaks), start farming the corresponding Element Chips and Weekly Boss materials. If you know their faction, you can guess their enemy drop material. Generic items (Dennies, EXP materials, skill materials) are always safe to pre-farm. As a general rule: start pre-farming 2-3 weeks before a banner you want to pull on.
The fastest method is Combat Simulation at the highest difficulty you can clear. The level 60+ domains give the best drop rates per stamina. You can also purchase chip material boxes from the Hollow Zero shop (using Investigation Points) and the Signal Shop (using Residual Signal currency). These are great filler purchases if you have extra currency.
