Mastering Mech-Accord Caster: Kjera Guide in Arknights

Kjera might appear serene and collected, but don't let her demeanor deceive you—she's a formidable 5-star Mech-Accord Caster capable of locking down and eliminating enemies with an impressive level of control. Introduced as the welfare Operator during the Break the Ice event, Kjera brings a distinctive style of Arts damage to Arknights through her drone companion, which scales damage the longer it focuses on a target. She merges consistent DPS with crowd-control elements, making her an ideal fit for teams seeking safe, scalable ranged Arts output.

Unlike burst-focused Casters in this strategy game, Kjera adopts a more methodical approach. Her basic attacks may not pack the strongest punch, but with a short attack interval and the escalating power of her drone, she becomes increasingly lethal the longer a battle persists. With the right setup, she can match the performance of even Core Casters of similar rarity—and the best part? She's free, making her an excellent choice for both new and returning players.

Operator Overview

Kjera is part of the Mech-Accord branch, meaning she attacks in tandem with a drone. This drone inflicts Arts damage starting at 20% of her ATK and increases by 15% with each consecutive hit on the same target, up to a maximum of 110%. Coupled with her rapid attack rate, this mechanic delivers impressive sustained DPS, particularly against stationary or slow-moving enemies. Additionally, Kjera is obtained not through banners or gacha, but via her guidebook, or Record Restoration.

This system rewards targeting consistency. The longer her drone can focus on one enemy, the more potent her damage becomes. It makes her a natural choice for bosses or mini-bosses that remain within range for extended periods. However, be mindful that any forced retargeting will reset the ramp-up, so careful positioning and control are crucial.

She also benefits from operators who reduce enemy RES or apply Freeze, as they synergize well with the Cold effect from her S2. Additionally, operators who buff ATK or ASPD can indirectly enhance her drone’s effectiveness.

Recommended Synergy:

• Slowers like Angelina or Istina: Extend Cold durations and reduce escape chances
• Freezers like Gnosis: Stack control effects for guaranteed freezes
• Tanky Defenders like Saria: Pin enemies down for drone lock-on consistency
• ATK Buffers like Warfarin or Shamare: Boost her and her drone’s base damage

Be mindful of where you place Kjera. Her talent requires melee tiles within her range, so scout your map layout and choose deployment zones that allow you to meet this condition without sacrificing coverage.

Kjera is a quiet powerhouse. With her slow-building drone pressure, Cold debuff potential, and reliable team-friendly setup, she outperforms expectations for a welfare unit. Whether you're using her for consistent lane control or strategic boss damage, she has the tools to deliver—especially when placed and built smartly.

For even better map control and precise drone management, consider playing Arknights on PC with BlueStacks. The enhanced visuals and quick response time make it easier to position her correctly, time your skills, and maintain steady drone pressure through even the most challenging stages.
