Mastering Mech-Accord Caster: Kjera Guide for Arknights

Author : Thomas May 27,2025

Kjera may appear calm and composed, 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 impressive control. Introduced as a welfare Operator during the Break the Ice event, Kjera offers a unique approach to Arts damage through her drone companion, which increases its damage the longer it targets a single enemy. Her blend of consistent DPS and crowd-control elements makes her an excellent choice for teams seeking reliable, scalable ranged Arts damage.

Unlike burst-focused Casters, Kjera's strategy is more methodical. While her basic attacks may not be the most powerful, her short attack interval and the escalating power of her drone make her increasingly lethal as battles progress. With the right setup, she can match the performance of Core Casters of similar rarity—and being a free unit, she's an excellent addition for both new and returning players.

Operator Overview

As a member of the Mech-Accord branch, Kjera attacks alongside a drone that delivers Arts damage. Starting at 20% of her ATK, the drone's damage 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 ensures impressive sustained DPS, particularly against stationary or slow-moving enemies. 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 greater her damage output becomes. This makes her ideal for tackling bosses or mini-bosses that linger within range. However, be cautious of forced retargeting, which can reset her damage ramp-up. Strategic positioning and control are crucial for maximizing her effectiveness.

Kjera synergizes well with operators who reduce enemy RES or apply Freeze, enhancing the Cold effect from her S2. Operators that boost ATK or ASPD can also indirectly amplify her drone's effectiveness.

Recommended Synergy:

  • Slowers like Angelina or Istina: Extend Cold durations and minimize enemy escape chances.
  • Freezers like Gnosis: Stack control effects to ensure guaranteed freezes.
  • Tanky Defenders like Saria: Help pin enemies in place for consistent drone lock-on.
  • ATK Buffers like Warfarin or Shamare: Increase 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 meet this condition without sacrificing coverage.

Kjera is a silent powerhouse. Her drone's gradual pressure, combined with her Cold debuff potential and team-friendly setup, enables her to outperform expectations for a welfare unit. Whether you're using her for consistent lane control or strategic boss damage, she has the tools to succeed—especially when positioned and developed thoughtfully.

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