Introduction to Jinzhou Keeper Guide

Wuthering Waves Jinzhou Keeper Guide: Jinzhou Keeper is a 4-star Rectifier weapon in Wuthering Waves, designed to honor the Midnight Rangers and their unwavering dedication to protecting Jinzhou. As part of the Rangers weapon series, it embodies their watchful presence and resilience. The weapon’s flavor text paints a vivid scene: “Cast your gaze towards the north, where the city’s silhouette fades, its gates veiled by the tranquil rain.” This poetic description reinforces the theme of vigilance and mystery surrounding Jinzhou’s defenders. Jinzhou Keeper was officially released on May 23, 2024, offering players a weapon rich in lore and significance.
Overview and Performance
Jinzhou Keeper is a 4-star Rectifier weapon in Wuthering Waves, designed to provide a strong balance between offensive power and survivability. At Level 1, it starts with a Base ATK of 31 and grants an additional 8.1% ATK as its secondary stat. As the weapon is upgraded, its power significantly increases, reaching a Base ATK of 387 at Level 90, with a secondary stat bonus of +36.4% ATK. This scaling makes it a solid choice for characters who benefit from consistent ATK boosts.

The weapon’s defining trait is its unique skill, Guardian, which enhances both ATK and HP. At Rank 1, activating the wielder’s Intro Skill triggers a buff that increases their ATK by 8% and their HP by 10% for 15 seconds. This effect is particularly valuable in combat scenarios where a character frequently uses their Intro Skill, allowing for a steady boost in both offensive output and durability. As the weapon’s refinement level increases, the potency of these buffs improves, making it even more effective for sustained engagements.
Jinzhou Keeper excels as a top-tier Rectifier choice for players looking to maximize their character’s damage potential while maintaining some additional survivability. The combination of a respectable Base ATK, high ATK scaling, and an ability that provides both offensive and defensive benefits makes it well-suited for aggressive playstyles. The additional HP boost from Guardian ensures that characters can stay in battle longer, making it an ideal weapon for those who rely on a mix of damage and resilience.
