ZZZ Weekly Boss Farming Route — Notorious Hunt & Expert Challenge Guide | Zenless Zone Zero
ZZZ weekly bosses live in the Notorious Hunt mode: each week you may claim the boss reward for free 3 times, after which every run costs 60 Battery Charge. Each boss drops its own Core Skill upgrade material, so look up which material the Agent you're building actually needs and spend all 3 free claims on that one boss instead of spreading them thin. The HIA Club Expert Challenge is where you farm Higher Dimensional Data at 40 Battery per run (80 in Exhaustion Mode). Because Battery regenerates slowly, the priority is simple: use the 3 free claims first, then spend Battery.
How Notorious Hunt works and what it costs
Notorious Hunt is where you fight ZZZ's weekly bosses for the high-tier Core Skill upgrade materials that no other source in the game gives you. The reward rules:
- Each week you may reap the boss reward for free 3 times, costing no Battery.
- Once those 3 free claims are gone, each further reward costs 60 Battery Charges.
- You can still fight the boss as often as you like for practice, but only free or paid claims actually pay out.
Cross-check which material each Agent needs in the GameVika item database before spending Battery, so you don't farm the wrong boss.

Weekly boss table: who drops what, and their weaknesses
Here is every Notorious Hunt boss currently in the game with its material drop, weakness and resistance — all sourced from official HoYoLAB data and matched against the GameVika item database. Bringing a team that hits the weakness breaks the Daze bar far faster:
| Boss | Material dropped | Weakness | Resists |
|---|---|---|---|
| Twin Marionettes | Finale Dance Shoes | Ether / Ice | — |
| Unknown Corruption Complex | Living Drive | Electric / Ether | — |
| Newborn Dead End Butcher | Ferocious Grip | Ice / Ether | — |
| Corrupted Overlord - Pompey | Scarlet Engine | — | Electric |
| Sacrifice - Bringer | Sycophant's Refinement | Ice | — |
| Miasma Priest | Exuvia of Refinement | Ether | Ice |
| Wandering Hunter | Crimson Miasma Spike | Ice | — |
| Ye Shiyuan the Thrall | Clouded Crystalline Substance | Ice / Wind | Electric |
Which boss to farm for which Agent
This is exactly why you shouldn't spread your claims thin: each weekly boss material only serves a fixed group of Agents. Find the Agent you're building in the right column, then aim all 3 free claims at the matching boss material on the left. Click an Agent's name for their full build page on GameVika:

HIA Club Expert Challenge: farming Higher Dimensional Data
The HIA Club Expert Challenge is where you farm Higher Dimensional Data — the high-tier Core Skill material, distinct from the weekly boss drops above. Each run costs 40 Battery Charges, or 80 if you enable Exhaustion Mode (harder, richer rewards). Since this stage has no free claims like the weekly boss does, only come here after you've used up your free boss claims.
Battery budget: how to spend without waste
Battery is the bottleneck on everything you farm. The baseline numbers worth memorizing:
- Notorious Hunt: 3 free claims per week, then 60 Battery per claim (the most expensive run in the game).
- HIA Club Expert Challenge: 40 Battery per run, 80 in Exhaustion Mode.
Because each of those 3 free boss claims is worth 60 Battery if you had to buy it, always burn your free claims before the weekly reset — it's the single biggest chunk of "free" Battery players forget. If you're still grinding gear instead, put the Battery into Drive Disc farming during weeks when nobody needs a Core Skill upgrade.
Notorious Hunt3 free/week → 60 Battery 
Expert Challenge40 Battery (80 Exhaustion) Your weekly farming route, in order
Rolled into a weekly habit:
- Start of week: review which Agent you're mid-way through building, and check the table above for the material they need.
- Burn all 3 free Notorious Hunt claims on the boss that drops that exact material — bring a team that hits the boss's weakness to shorten the fight.
- Still short: buy extra claims at 60 Battery each, but only if that Agent is genuinely close to a Core Skill breakpoint.
- Battery left over: move to the Expert Challenge (40 Battery a run) if you need Higher Dimensional Data, or go farm Drive Discs if the build is still weak.
- Before weekly reset: double-check you actually spent all 3 free claims — they do NOT roll over into next week.
If you're unsure who to build first, check the character tier list and the team compositions to lock a team core before pouring Battery in — farming the right Agent matters more than farming a lot.
FAQ
Do free Notorious Hunt claims roll over to next week?
No. You get 3 free reward claims each week and they do NOT accumulate — anything unused is simply gone at the weekly reset. Since each free claim is worth 60 Battery if you had to pay for it, forgetting them is the single biggest resource waste ZZZ players make. Build the habit of checking before reset.
How is Notorious Hunt different from the Expert Challenge?
They drop two different material types. Notorious Hunt drops per-boss weekly boss materials, with 3 free claims a week and 60 Battery per claim afterwards. The HIA Club Expert Challenge drops Higher Dimensional Data, has no free claims, and costs 40 Battery a run (80 in Exhaustion Mode). Both feed Core Skill upgrades but at different steps, so you'll need both to finish building an Agent.
Does it matter if my team does not hit the boss weakness?
You can still clear it, but the fight drags noticeably: the Daze bar builds slower, and any element listed in the boss's "Resists" column deals reduced damage. The table above lists each weakness so you can swap your team before entering — if you're fuzzy on how the Daze bar works, read the Stun/Daze guide first, since breaking Daze on time is what shortens boss fights the most.
