Lighter remains one of the most memorable additions to Zenless Zone Zero since his explosive debut as the game’s inaugural limited S-Rank male Agent. Even in 2026, new and returning players are still eager to recruit the undefeated Champion of the Outer Ring. To fully unleash his Stun potential and fiery combat style, you need to gather a specific set of Lighter materials. This guide breaks down every required resource, where to farm them efficiently, and how to integrate Lighter into your current team compositions.

Lighter is a Fire Stun Agent who excels at building up Daze and locking down enemies. His kit revolves around rapid-fire punches and a charging mechanic that lets him deliver devastating interrupt windows for your main damage dealers. With his unparalleled close-quarters technique, he earned the nickname “undefeated Champion” by ending the twenty-fight winning streak of the notorious thug, Bellum. Beyond raw power, Lighter’s personality shines through his deep friendship with Billy from the Cunning Hares, both of whom share a history as champions in the Old Oil Field. This backstory has only added to his popularity among Proxies.

To acquire Lighter in 2026, you must pull on the time-limited Exclusive Channel banner. Originally introduced in version 1.3, this banner now occasionally reruns alongside other limited characters. Keep an eye on the in-game notices for his next availability window. Once you’ve added Lighter to your roster, your next step is to maximize his level, talents, and Core Skill enhancements. The full list of required materials has been continuously updated since his release, and the table below reflects the final confirmed requirements for reaching level 90 with maximum skills.

All Lighter Ascension and Skill Materials

The following table lists every material you need to fully upgrade Lighter. Quantities assume you are taking him from level 1 to 90 and raising all his combat talents to the highest possible rank. Note that some high-level materials require farming the most challenging stages of Hollow Zero or Expert-level HIA commissions.

Resource Type Material Name Total Required Primary Source
Agent EXP Official Investigator’s Log 421 W-Engine EXP, 3,200,000 Dennies equivalent HIA Commemoration Commission
Ascension Material Burn Seal Controller’s Certification 46 (including higher rarities) Expert Challenge: Flaming Fraternity
Common Enemy Drop Anomaly-Tainted Fluid (and its upgrades) 36 Defiler’s Core, 30 Bane Engine Ethereal encounters in Hollow exploration
Weekly Boss Drop Blazewood Heart of the Conqueror 18 Notorious Hunt: Overlord’s Feast
Skill Talent Book Stun Dynamics (Basic, Advanced, Specialized) 9 Advanced, 63 Specialized HIA Career Guidance: Stun Drill
Core Skill Node Materials Higher Dimensional Data: Frenzy 5 Notorious Hunt weekly boss or Signal Shop
Component for Talent upgrades Hamster Cage Pass (for each talent branch) 5 per talent Reoccurring events and Inter-Knot Store

Dennies act as the universal currency required for every upgrade step, totaling well over 4 million if you fully invest in Lighter. You can farm Dennies in the relevant HIA commission or by completing daily training missions.

Efficient Farming Routes for Lighter Materials

Because many of Lighter’s materials are shared with other Fire or Stun Agents, smart planning will save you a significant amount of battery charge. Ascension materials such as the Burn Seal Controller’s Certification can be obtained from the Expertise Challenge “Flaming Fraternity” on Monday, Thursday, and Sunday. Aim for the highest difficulty tier as soon as your Inter-Knot level allows to get purple and gold rarities consistently.

For talent books, the Stun Dynamics line drops from the HIA Career Guidance domain “Stun Drill.” This domain is open daily, so you can farm it whenever you have spare battery. Since Lighter requires a massive number of Specialized Stun Dynamics, consider using the Waveplate Double Drop event periods to stock up.

The weekly boss material, Blazewood Heart of the Conqueror, is a hard cap on progress. You can only claim rewards from the Notorious Hunt “Overlord’s Feast” three times per week. Start farming this early, as you need 18 pieces to fully max Lighter’s talents. Any excess can be converted into other older weekly materials using the Synthesis Station.

Anomaly-Tainted Fluid and its upgraded versions drop from standard Ethereal enemies across Hollow expeditions and story stages. The most optimized route is to repeatedly clear the highest-level Free Exploration zone in Hollow Zero and target Elite-class Ethereals that guarantee a drop. Use the in-game enemy collection tracker to pinpoint specific zones loaded with Fluid-dropping foes.

Building a Team around Lighter

Lighter’s Stun kit synergizes exceptionally well with Attack agents who benefit from extended enemy downtime. Pair him with characters like Soldier 11 or Ellen, as their high burst damage can capitalize on the stun windows Lighter creates. Additionally, because Lighter is a member of the Sons of Calydon, any Burn-type support, such as Lucy, can activate his additional ability that increases stun accumulation against burning enemies.

For a balanced composition, use Lighter as your stun engine, a hard-hitting DPS, and a support that either buffs fire damage or provides grouping utility. Agents like Koleda can accelerate stun via frequent chain attacks, but Lighter’s rapid-fire strikes often outperform in single-target scenarios. Experiment with Drive Discs that increase Daze inflicted and energy regeneration to keep Lighter’s enhanced punch state active for as long as possible.

In the current 2026 meta, Lighter remains a top-tier pick for any team that relies on burst windows. His unique combination of elemental coverage and relentless pressure makes him a staple in both Shiyu Defense and Timely Assistance challenges. Even with the release of newer limited Stun agents, Lighter’s ability to fit into multiple elemental teams ensures he never falls out of favor.

Lighter’s materials may seem daunting at first, but with a consistent farming schedule, you can have him fully built in a matter of weeks. Prioritize weekly boss drops and ascension seals, and use all battery overflow events to your advantage. Once completed, Lighter will reward you with some of the most satisfying combat sequences in Zenless Zone Zero. Now it’s time to step into the ring and prove that the undefeated Champion still has what it takes.
