Kjera might appear calm and composed on the surface, but don't let that fool you—she's a formidable 5-star Mech-Accord Caster in Arknights, 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 offers a unique approach to Arts damage through her drone companion, which scales its damage the longer it remains focused on a target. She seamlessly blends consistent DPS with crowd-control elements, making her a perfect fit for teams seeking reliable and scalable ranged Arts output.
Unlike the burst-focused Casters common in this strategy game, Kjera's method is more deliberate. While her basic attacks may not hit the hardest, her short attack interval and the escalating power of her drone make her increasingly lethal as battles prolong. With the right setup, she can compete with Core Casters of similar rarity—and the best part? She's free, making her an excellent addition for both new and returning players.
Operator Overview
Kjera is part of the Mech-Accord branch, which means she attacks in coordination with a drone. This drone inflicts Arts damage that starts at 20% of her ATK and increases by 15% with each consecutive hit on the same target, reaching a maximum of 110%. Paired with her rapid attack rate, this mechanic results in remarkable sustained DPS, especially effective against stationary or slow-moving enemies. Importantly, Kjera is acquired not through banners or gacha, but via her guidebook, or Record Restoration.
This system rewards consistent targeting. The longer her drone can lock onto one enemy, the more potent her damage becomes, making her ideal for bosses or mini-bosses that linger within range. Be cautious, though; any forced retargeting will reset the ramp-up, so positioning and control are crucial.

Kjera also synergizes well with operators who can reduce enemy RES or apply Freeze, enhancing the impact of the Cold effect from her S2. Additionally, operators that 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 drone lock-on consistency
- ATK Buffers like Warfarin or Shamare: Boost her and her drone’s base damage
When placing Kjera, consider her talent's requirement for melee tiles within her range. Scout your map layout and choose deployment zones that allow you to fulfill this condition without compromising coverage.
Kjera is a silent powerhouse. With her gradually intensifying drone pressure, potential for Cold debuffs, and reliable team-friendly setup, she performs exceptionally well for a welfare unit. Whether you're using her for steady lane control or strategic boss damage, she has the tools to excel—especially when strategically positioned and enhanced.
For enhanced map control and precise drone management, consider playing Arknights on PC with BlueStacks. The improved visuals and swift response times make it easier to position Kjera accurately, time your skills, and maintain consistent drone pressure, even through the most challenging stages.
