Lee Joohee, Pilgrim of the Labyrinth has been released as a new Light-attribute Buster. As a Buster, she works best paired with a Stacker, and it is recommended to run her alongside the Supporter Shimizu Akari, who was recently reworked specifically for Busters.

The alternate version of Lee Joohee already has her damage cycle mostly completed at low Advancement levels, with higher Advancements primarily increasing her damage output, meaning she runs smoothly even at low Advancements. However, since advancing your main DPS is crucial for high overall team damage, it is generally recommended to push her to high Advancements if possible.

Lee Joohee features interlocking skills that provide buffs and cooldown reductions. In particular, her ability to restore her Core Gauge with skills and reduce skill cooldowns with Core Attacks gives her exceptionally high sustained damage.

Her skill set and stat options represent the epitome of a self-centered DPS. Packed with self-buffs to boost her own damage and debuffs applied to enemies, she offers no separate buffs to allies, making her a Hunter meant to be played strictly for her personal damage output.

She also possesses many stacking debuffs to inflict on enemies. Thanks to her automatic extra attack mechanism called Lucent Beam, Lee Joohee generates a high hit count, allowing her to stack these debuffs extremely quickly.

Inheriting the typical trait of Busters who generally have complex skill usage, Lee Joohee also features a somewhat intricate rotation. This is because Basic Skills recover the Core Gauge, Core Attacks reduce the cooldown of her E skill, and empowered skills become activated throughout this process.

However, conceptually, it is easiest to approach by thinking of it as alternating between skills and Core Attacks before executing empowered skills. At Advancement 1, her rotation breaks down to: E - Core - Q - Core - E - Core - Q - E - Ultimate.

First, using E - Core - Q - Core makes E available again due to the Core Attack's E cooldown reduction. Using E - Core once more activates Empowered Q, which in turn activates Empowered E. After executing the entire sequence, cast the Ultimate, and during the remaining Overload duration, restart the cycle from the beginning until unleashing a Burst skill before tagging out.

Empowered Q accumulates stacks every time Q or a Core Attack is used, activating once 4 stacks are reached. Based on the rotation above, reaching the second E - Core completes exactly 4 stacks with one Q and three Core Attacks. Since the charging cycle for Empowered Q remains the same regardless of Advancement level, players do not need to worry about the rotation failing at lower Advancements.

The rotation is explained based on Advancement 1 because a base (Advancement 0) Lee Joohee cannot execute the rotation properly due to several factors, including the activation of Empowered E following Empowered Q, Ultimate cooldown reduction, and Power Gauge recovery.

Since Lee Joohee's rotation becomes complete at Advancement 1, step 1 is the essential tier. Subsequent Advancements 3 and 5 grant damage-boosting effects, meaning Advancement 1 alone is sufficient for her rotation to function smoothly. However, because the main DPS accounts for the largest portion of team damage, reaching Advancement 5 is virtually mandatory to unleash maximum damage.

Looking more closely at Advancement 1, the key additions are the 'Lucent Beam' mechanic and the trigger for additional empowered skills. Lucent Beam is an automatic additional attack system that triggers upon performing her two Basic Attacks and Core Attacks. While it deals extra damage and applies a debuff that increases damage taken from Lee Joohee, even more important are its Power Gauge recovery and Ultimate cooldown reduction effects, allowing her to cast her Ultimate in every cycle.

Additionally, the skill name of Empowered E changes, raising its base damage, and a mechanic is added where Empowered E is activated after Empowered Q, laying the groundwork to cast E - Q - Ultimate in the second cycle. Finally, receiving healing triggers the Focus of Light effect, which increases Attack and Light Overload damage, allowing her to unleash even greater firepower.

Advancement 3 activates a self-buff upon using E that increases Attack by 15% and Defense Penetration by 5%, while restoring 400 Mana for herself and her team. Furthermore, enemies inflicted with the 'Extinction' debuff triggered by casting the Ultimate take 50% increased damage from Basic Skills and Lucent Beam, which significantly boosts her extra damage output during the remaining Overload time after using her Ultimate in the rotation. On top of this, Condensation of Doom is added, which increases Ultimate damage by up to 200% at maximum stacks and Burst damage by 60% when using Core Attacks, Q, or Empowered Q on Overloaded targets, massively raising Lee Joohee's overall damage output.

Advancement 5 represents the completion of her firepower enhancements. Lucent Beam is empowered, doubling its Attack multiplier from 400% to 800%, while the debuff increasing damage taken from Lee Joohee applied on Lucent Beam hit rises significantly from 4% to 7% per stack. When Overload triggers, an additional buff increasing Attack and Overload damage is granted, along with a 10% increase in damage dealt per Extinction stack. Combined with Stackers and Supporters, Lee Joohee's final damage output accelerates even faster.

While the Light element features various Supporters such as Shimizu Akari, Min Byung-Gyu, and Laura Walker, the best Supporter for Lee Joohee is Shimizu Akari. Shimizu Akari received an additional buff tailored specifically for Busters, granting her unique buffs that increase Overload damage and Burst damage. Furthermore, she possesses the ability to rapidly stack 'Extinction' to enable the Extinction synergy buffs utilized by Advancement 5 Lee Joohee, putting her in a completely different power tier compared to other Supporters.

The remaining slot naturally goes to Antoine Martinez. Since Lee Joohee belongs to the Buster class, she requires an Elemental Accumulation to trigger Overload, and Antoine is responsible for this role. Antoine has also received enhancements with increased buff durations and strengthened weapon team buff capabilities, giving him superior supporting power. Naturally, regardless of buff capabilities, the Overload duration remains the same at 15 seconds, so using channeling Q while quick-swapping with Lee Joohee is still required to deal maximum damage without wasting Overload uptime.
