Who is Cissia and why start farming now?
Cissia is an S-Rank Electric agent dropping in Zenless Zone Zero version 2.7 Phase 2. Maxing her out takes a mountain of materials, and the players who farm ahead can run her at full strength the moment she lands. This guide covers every resource she needs, where to get it, and how to spend your Battery Charges efficiently.
What are all of Cissia's promotion materials?
Promotion materials gate how high you can push Cissia's level. Getting her from 1 to 60 requires:
The early ascension at level 10 only asks for 4 Basic Attack Certification Seals and 24,000 Denny. The final push from 50 to 60 demands 20 Pioneer's Certification Seals and 400,000 Denny in one go.
Promotion materials by level
What skill materials does Cissia need?
All five of Cissia's skills (Basic Attack, Dodge, Special Attack, Chain Attack, and Assist) pull from the same Shock Chip pool. Maxing them all requires:
Early skill levels are cheap. Levels 2 and 3 only need Basic Shock Chips. The cost jumps hard at level 8 when Specialized Shock Chips become the requirement. Level 12 costs 15 Specialized Shock Chips and 1 Hamster Cage Pass per skill.
Core Skill materials
The Core Skill uses a different material track. Ranking it from A to F requires Exuvia of Refinement and Higher Dimensional Data - Bloodstained Miasma Feather, plus Denny:
Full A-to-F progression costs 9 Exuvia of Refinement, 60 Bloodstained Miasma Feather, and 405,000 Denny.
How do you get Exuvia of Refinement?
Exuvia of Refinement drops from the Miasma Priest weekly boss in Scott Outpost's Notorious Hunt mode. You unlock the boss by clearing one of the weekly boss challenges. Each week gives you 3 free reward attempts. After that, you can run Pursuit to the Depths mode at 60 Battery Charges per attempt.
With 1 drop per session and 9 total needed, expect to spend at least 3 weeks of free rewards plus Battery runs.
How do you get Bloodstained Miasma Feather?
Higher Dimensional Data - Bloodstained Miasma Feather comes from the Expert Challenge boss Sacrifice - Covenant Guardian at the HIA Club. Each session costs 40 Battery and drops 5 feathers. 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 fight.
You need 60 total. That's 12 standard runs (480 Battery) or 6 Burnout runs (480 Battery). The math is identical, so pick whichever cadence fits your schedule.
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 Denny. The S-Rank W-Engine totals are:
A-Rank W-Engines need slightly less (3 Attack, 26 Reinforced, 24 Specialized) and 320,000 Denny. B-Rank costs even less. Farm Attack Components from W-Engine Modification mode in Combat Simulation against the Armored Hati card.
How much Denny does Cissia need in total?
Adding promotion, skills, Core Skill, and S-Rank W-Engine, the combined Denny cost is massive. The character-side total (promotion plus all skills) comes to roughly 3,705,000 Denny. The S-Rank W-Engine adds another 400,000.
Drive Disc upgrades cost more. Each S-Rank Drive Disc piece runs around 72,000 Denny, putting the six-piece total at roughly 432,000 additional Denny.
Denny resource overview
Where to farm Drive Disc upgrade materials
Cissia's Drive Discs use Ether Plating Agents as upgrade material. The most efficient sources 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 costs somewhere between 600 and 800 Battery total.
Summary: What to farm first
With limited Battery Charges each day, here's the priority order that makes the most sense before Cissia's banner:
- Miasma Priest (Notorious Hunt) every weekly reset for Exuvia of Refinement
- Sacrifice - Covenant Guardian (Expert Challenge) for Bloodstained Miasma Feather
- Lightfoot Rover MK II (Combat Simulation) for Shock Chips
- Hati (Combat Simulation) for Attack Certification Seals
- 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. Combat Simulation runs can fill in the rest of your Battery budget around them.
