Kjera may appear calm and composed, but don't let that fool you—she's a formidable 5-star Mech-Accord Caster capable of locking down and eliminating enemies with impressive control. Introduced as the welfare Operator during the Break the Ice event, Kjera offers a unique approach to Arts damage in Arknights, utilizing her drone companion, which increases damage the longer it remains focused on a target. Her blend of consistent damage per second (DPS) and crowd-control elements makes her a valuable asset to teams seeking reliable, scalable ranged Arts output.
Unlike burst-focused Casters in this strategy game, Kjera adopts a more methodical approach. While her basic attacks may not be the strongest, her short attack interval combined with her drone's escalating power makes her increasingly dangerous as battles prolong. With the right setup, she can match the performance of 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, utilizing a drone that delivers Arts damage starting at 20% of her ATK and increasing by 15% with each consecutive hit on the same target, up to a maximum of 110%. Coupled with her rapid attack rate, this mechanic allows her to achieve impressive sustained DPS, particularly against stationary or slow-moving enemies. Unlike other Operators obtained through banners or gacha, Kjera is accessible via her guidebook, or Record Restoration.
This system encourages targeting consistency, as the longer her drone focuses on one enemy, the higher her damage output. This makes her an ideal choice for tackling bosses or mini-bosses that remain within range for extended periods. However, be mindful that any forced retargeting will reset the drone's ramp-up, emphasizing the importance of careful positioning and control.

Kjera synergizes well with operators who lower enemy RES or apply Freeze, enhancing the Cold effect from her S2. Additionally, operators who boost ATK or ASPD can indirectly amplify 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 consistent drone lock-on
- ATK Buffers like Warfarin or Shamare: Boost her and her drone’s base damage
When positioning Kjera, consider her talent's requirement for melee tiles within her range. Scout your map layout and choose deployment zones that meet this condition without compromising coverage.
Kjera is a silent powerhouse. With her gradually building drone pressure, Cold debuff potential, and reliable team-friendly setup, she outperforms expectations for a welfare unit. Whether you deploy her for consistent lane control or strategic boss damage, she delivers—provided she's placed and developed smartly.
For enhanced map control and precise drone management, consider playing Arknights on PC with BlueStacks. The improved visuals and faster response time make it easier to position Kjera effectively, time your skills accurately, and maintain steady drone pressure through even the most challenging stages.
