Cissia ZZZ Pre-Farm Guide: All Materials You Need

Who is Cissia and why start farming now?

Cissia is an S-Rank Electric agent arriving in Zenless Zone Zero version 2.7 Phase 2. Like every new agent in the game, she demands a significant pile of resources before she hits her ceiling — and the players who stockpile materials ahead of a banner release are the ones who can run her at full power on day one. This guide breaks down every material she needs, where each one comes from, and how to prioritize your Battery Charges across the farming sessions that matter most.

What are all of Cissia's promotion materials?

Promotion (ascension) materials determine how far you can level Cissia. To take her from level 1 to 60, you need the following, according to Game8's pre-farm guide:

The Certification Seals scale in tier as Cissia's level climbs. The first ascension gate at level 10 only asks for 4 Basic Attack Certification Seals and 24,000 Denny. By the time you push through the level 50 to 60 gate, you need 20 Pioneer's Certification Seals and 400,000 Denny in a single step.

What skill materials does Cissia need?

Cissia's skills (Basic Attack, Dodge, Special Attack, Chain Attack, and Assist) all draw from the same Shock Chip pool. To max all five of those skills, you need the following, per Game8's materials guide:

The skill level progression starts cheap — levels 2 and 3 only need Basic Shock Chips — but the cost spikes hard once you hit level 8, where Specialized Shock Chips take over. Level 12, the cap, demands 15 Specialized Shock Chips and 1 Hamster Cage Pass per skill.

Core Skill materials

Cissia's Core Skill uses a separate material track. Getting it from rank A to F requires both Exuvia of Refinement and Higher Dimensional Data - Bloodstained Miasma Feather, plus a large Denny investment:

Fully maxing the Core Skill from A to F costs 9 Exuvia of Refinement, 60 Bloodstained Miasma Feather, and 405,000 Denny in total, according to Game8's data.

How do you get Exuvia of Refinement?

Exuvia of Refinement drops from the weekly boss Miasma Priest, found in Scott Outpost's Notorious Hunt game mode. You unlock the boss by completing one of the weekly boss challenges in Notorious Hunt. Each week, you get 3 free reward attempts. After those are used up, you can activate Pursuit to the Depths mode, which costs 60 Battery Charges per additional attempt, according to both lootbar.gg and Game8's guides.

At 1 drop per session and a cap of 9 needed, plan on spending at least 3 weeks of free rewards just on this material, assuming you supplement with Battery runs.

How do you get Bloodstained Miasma Feather?

Higher Dimensional Data - Bloodstained Miasma Feather comes from the Expert Challenge boss Sacrifice - Covenant Guardian, located at the HIA Club. Each session costs 40 Battery Charges, and the boss drops 5 per run. During the current patch, Burnout Mode is active for featured S-Rank characters' related Expert Challenge bosses, letting you spend 80 Battery for double rewards in one battle, per Game8's guide.

With 60 total needed, you're looking at 12 standard runs (480 Battery) or 6 Burnout runs (480 Battery) — the math is identical, so the choice is just whether you want to run it less often.

What are Cissia's W-Engine materials?

If you pull Cissia's signature W-Engine, leveling it from 0 to 60 requires Attack Components at all three tiers, plus a substantial Denny cost. According to both sources, the S-Rank W-Engine totals are:

If you're running an A-Rank W-Engine instead, the component counts drop slightly (3 Attack, 26 Reinforced, 24 Specialized) and Denny falls to 320,000. B-Rank costs even less. Farm Attack Components from the W-Engine Modification mode in Combat Simulation against the Armored Hati enemy card, per Game8's guide.

How much Denny does Cissia need in total?

Adding up promotion, skill, Core Skill, and S-Rank W-Engine, the combined Denny cost across all upgrades is substantial. According to lootbar.gg's pre-farm breakdown, the character-side total alone (promotion plus all skills) comes to approximately 3,705,000 Denny, with the S-Rank W-Engine adding another 400,000 on top.

Drive Disc upgrades add further cost. Game8 estimates around 72,000 Denny per S-Rank Drive Disc piece, putting the six-piece total at roughly 432,000 additional Denny.

Where to farm Drive Disc upgrade materials

Cissia's Drive Discs use Ether Plating Agents as upgrade material. The most efficient sources, per Game8, are:

• Combat Simulation at the HIA Club
• Routine Cleanup at Scott Outpost
• Drive Disc dismantling
• Commission rewards and shops

Spending 100 Battery on the relevant Combat Simulation enemies yields roughly 20 to 25 Ether Plating Agents. Getting to the full 150 needed for six S-Rank Drive Discs will cost somewhere between 600 and 800 Battery total.

Summary: What to farm first

With limited Battery Charges each day, here is the priority order that makes the most sense before Cissia's banner:

1. Miasma Priest (Notorious Hunt) every weekly reset for Exuvia of Refinement
2. Sacrifice - Covenant Guardian (Expert Challenge) for Bloodstained Miasma Feather
3. Lightfoot Rover MK II (Combat Simulation) for Shock Chips
4. Hati (Combat Simulation) for Attack Certification Seals
5. Armored Hati (Combat Simulation) for Attack Components if pulling the signature W-Engine

The weekly bosses are the hardest bottleneck, so those always come first. The Combat Simulation runs can fill in the rest of your Battery budget around them.
