Arknights Endfield Estella Build & Analysis

Estella is a 4★ Guard in Arknights Endfield built around Cryo application, Lift control, and short-window Physical Susceptibility. Her kit is straightforward to execute, but it only pays off when the team is ready to act inside the debuff window she creates.

If you are comparing Estella to other operators or trying to understand where she stands in the broader meta, this article is written to slot directly into our Arknights Endfield Tier List, where all characters are evaluated under the same conditions and assumptions.

Analysis & Verdict

Estella’s kit is split between two jobs: apply Cryo quickly in a straight line, then convert Solidification states into crowd control and Physical vulnerability. She is not a standalone DPS. She is a window creator. If the team is ready to act, she makes that action stronger. If the team is late, the window closes and her contribution becomes mostly Lift and basic damage.

Her Basic Attack is standard, but the important number is the 17 Stagger on Final Strike when controlled. That means she can participate in Stagger loops, but she does not define them. If the team already produces Stagger consistently, she benefits. If the team does not, her finisher value appears less often and her baseline becomes simple Physical sequences.

Onomatopoeia is her most reliable skill because it does not require setup. It fires forward, hits multiple targets in a line, deals Cryo damage, and applies Cryo Infliction. This is the button you press when you need stacks now, not later. It also matters because Commiseration ties SP return to Shatter, and Shatter depends on the team actually converting Solidification into a break. If Shatter is not happening, Commiseration never pays out and her rotation slows.

Distortion is the center of her debuff utility. It only triggers when a target suffers Solidification, which means Estella is waiting for the freeze state to exist before she can apply Physical Susceptibility. In a controlled rotation, this is predictable: Solidification happens, Estella dashes in, applies Lift and vulnerability, and the DPS unloads. In messy fights, Solidification can land on the wrong target, be broken early, or simply not occur at the moment you need it. When that happens, Distortion becomes unusable until the condition appears again.

Tremolo follows the same logic. It is circular Physical damage, and it has an extra control clause: enemies with Physical Susceptibility get forcibly Lifted. This means Tremolo does not create the debuff; it exploits the debuff. If Physical Susceptibility is not active, Tremolo is just a slam. If it is active, Tremolo adds guaranteed Lift control, which can stabilize add waves and punish enemies already marked for burst.

Talents and Potentials push her into tighter, faster rotations. Commiseration is SP economy tied to Shatter. Laziness Pays Off Now makes her ignore Cryo Infliction and reduces incoming Cryo damage in Cryo-heavy encounters. Potential I extending Physical Susceptibility duration by 3 seconds increases the time your DPS has to act inside the window. Potential III improving Onomatopoeia range and first-hit damage improves her consistency in real rooms, where line-of-sight and spacing are never perfect.

Estella performs best when the fight has a clear rotation rhythm: apply Cryo, trigger Solidification, convert it with Distortion, then burst during Physical Susceptibility. She performs worse when targets die too fast, move constantly, or when the team cannot reliably control who gets Solidified and when. In those fights, she still applies Cryo and Lift, but her defining value — Physical Susceptibility — lands inconsistently.
