Sunna is an S Rank Physical Support agent in Zenless Zone Zero whose upgrade path is built around Support promotion materials, Physical skill chips, and two late‑game boss drops. Having her entire material curve mapped out makes it much easier to plan Battery and Denny before committing to her banner.
Quick answer: To completely finish Sunna (level 60 promotion, all skills, core skills A→F, and S Rank W‑Engine 60), you need 4 Basic Support Certification Seals, 32 Advanced Support Certification Seals, 30 Ruler Certification Seals, 25 Basic Physical Chips, 75 Advanced Physical Chips, 250 Specialized Physical Chips, 9 Clouded Crystalline Substances, 60 Higher Dimensional Data: Bloodstained Miasma Feathers, 5 Hamster Cage Passes, 30 Specialized Support Components, 32 Reinforced Support Components, 4 Support Components, 150 Ether Plating Agents, and 3,337,000 Denny for her plus 400,000 Denny for the S Rank W‑Engine, on top of any Drive Disc enhancement costs.
Sunna promotion (ascension) materials to level 60
Promotion raises Sunna’s level caps. She uses the standard Support‑type Certification Seals and a single Denny pool.
| Promotion band | Support materials | Denny |
|---|---|---|
| Lv 10 → 20 | Basic Support Certification Seal ×4 | 24,000 |
| Lv 20 → 30 | Advanced Support Certification Seal ×12 | 56,000 |
| Lv 30 → 40 | Advanced Support Certification Seal ×20 | 120,000 |
| Lv 40 → 50 | Ruler Certification Seal ×10 | 200,000 |
| Lv 50 → 60 | Ruler Certification Seal ×20 | 400,000 |
| Total | Basic ×4, Advanced ×32, Ruler ×30 | 800,000 |
All three Certification Seal tiers drop from the Agent Promotion mode of Combat Simulation against the Bulky Intimidator enemy card.
You know you have everything for promotion when your inventory shows at least 4 Basic, 32 Advanced, and 30 Ruler Certification Seals, and 800,000 Denny reserved for Sunna.
Sunna basic skill level materials (per skill)
Each of Sunna’s Basic Attack, Dodge, Special Attack, Chain Attack, and Assist skills shares the same Physical Chip curve. These levels are separate from core skills A–F.
| Skill level | Physical Chips | Denny (per level) |
|---|---|---|
| Lv 1 → 2 | Basic Physical Chip ×2 | 2,000 |
| Lv 2 → 3 | Basic Physical Chip ×3 | 3,000 |
| Lv 3 → 4 | Advanced Physical Chip ×2 | 6,000 |
| Lv 4 → 5 | Advanced Physical Chip ×3 | 9,000 |
| Lv 5 → 6 | Advanced Physical Chip ×4 | 12,000 |
| Lv 6 → 7 | Advanced Physical Chip ×6 | 18,000 |
| Lv 7 → 8 | Specialized Physical Chip ×5 | 45,000 |
| Lv 8 → 9 | Specialized Physical Chip ×8 | 67,500 |
| Lv 9 → 10 | Specialized Physical Chip ×10 | 90,500 |
| Lv 10 → 11 | Specialized Physical Chip ×12 | 112,500 |
| Lv 11 → 12 | Specialized Physical Chip ×15, Hamster Cage Pass ×1 | 135,500 |
Maxing a single skill from level 1 to 12 uses:
| Per-skill total | Amount |
|---|---|
| Basic Physical Chip | 5 |
| Advanced Physical Chip | 15 |
| Specialized Physical Chip | 50 |
| Hamster Cage Pass | 1 |
| Denny | ~501,000 |
Maxing all five basic skills needs:
| All basic skills total | Amount |
|---|---|
| Basic Physical Chip | 25 |
| Advanced Physical Chip | 75 |
| Specialized Physical Chip | 250 |
| Hamster Cage Pass | 5 |
| Denny | 2,505,000 |
Physical Chips come from the Agent Skill mode of Combat Simulation against the Bulky Enforcer enemy card.
The Hamster Cage Pass is the choke point. It comes in very small quantities from the New Eridu City Fund battle pass and limited‑time events, so spending five passes to cap all of Sunna’s skills is a significant commitment.
Sunna core skill materials (A–F)
Core Skills A–F are Sunna’s deeper passives and consume a different pool of materials, including weekly boss drops. Raising her from A to F uses the following:
| Core skill tier | Clouded Crystalline Substance | Higher Dimensional Data: Bloodstained Miasma Feather | Denny |
|---|---|---|---|
| A | – | – | 5,000 |
| B | – | 2 | 12,000 |
| C | – | 4 | 28,000 |
| D | 2 | 9 | 60,000 |
| E | 3 | 15 | 100,000 |
| F | 4 | 30 | 200,000 |
| A → F total | 9 | 60 | 405,000 |
Both boss drops are tightly controlled by weekly or Battery limits.
Clouded Crystalline Substance source
Clouded Crystalline Substance drops from the Notorious Hunt boss Ye Shiyuan The Thrall at Scott Outpost.
You need nine Clouded Crystalline Substances in total for Sunna’s core skills, so three full weeks of free rewards cover the entire requirement if you focus on that boss.
Higher Dimensional Data: Bloodstained Miasma Feather source
Higher Dimensional Data: Bloodstained Miasma Feather comes from the Expert Challenge boss Sacrifice – Covenant Guardian at the HIA Club.
Each clear yields five Bloodstained Miasma Feathers. Sunna needs 60 to go from core skill A to F, so 12 standard runs (or six Burnout clears) are enough.
Sunna S Rank W-Engine materials
Sunna’s S Rank W‑Engine uses Support‑type components. The per‑level costs follow the standard S Rank weapon curve.
| W‑Engine level band | Support materials | Denny |
|---|---|---|
| Lv 10 → 20 | Support Component ×4 | 12,000 |
| Lv 20 → 30 | Reinforced Support Component ×12 | 28,000 |
| Lv 30 → 40 | Reinforced Support Component ×20 | 60,000 |
| Lv 40 → 50 | Specialized Support Component ×10 | 100,000 |
| Lv 50 → 60 | Specialized Support Component ×20 | 200,000 |
| Total | Support ×4, Reinforced ×32, Specialized ×30 | 400,000 |
The same totals also apply as a reference for her “signature W‑Engine” material planning. All three Support Component tiers come from the W‑Engine Modification mode of Combat Simulation against the Heavy Gunner enemy card.
Drive Disc upgrade materials for a full Sunna set
Drive Discs do not use Sunna‑specific items, but their costs are predictable and can be prefarmed alongside her other materials. A typical assumption for fully upgrading six S Rank Drive Discs is:
| Drive Disc upgrade scope | Ether Plating Agent | Denny |
|---|---|---|
| One Disc | 25 | 72,000 |
| Six Discs | 150 | 432,000 |
Ether Plating Agents come from several sources, but Combat Simulation and Routine Cleanup are the most efficient.
Once your inventory holds the Promotion Seals, Physical Chips, boss drops, Support Components, and Ether Plating Agents in the amounts listed above, you can take Sunna all the way to level 60, cap every skill and core skill, and finish both her weapon and Drive Disc set without hitting any unexpected bottlenecks.
