Arknights Endfield Arclight Build & Analysis

Arclight is a 5★ Vanguard in Arknights Endfield built around SP recovery and the Electric team’s core conversion loop: turning Electric Infliction into Electrification on demand. Her kit rewards strict sequencing. If you press skills randomly, the engine stalls. If you press them in order, the team’s burst window becomes much easier to control.

If you are comparing Arclight 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

Arclight’s kit is built around an internal loop: apply Electric Infliction, convert it into Electrification, then spend Electrification for extra hits and SP. The core mechanic is visible in two places: Tempestuous Arc gets a bonus attack and SP recovery when it consumes Electrification, and Exploding Blitz forces Electrification by consuming existing Electric Infliction.

This is why she is a core piece of Electric teams. If your lineup supplies Electric Infliction consistently, Arclight turns that into Electrification at the moment you want a burst window. That conversion is the bridge between “we have stacks” and “we cash stacks into real damage.”

The main friction is timing. Exploding Blitz has a delayed second hit. There is a visible gap before the lingering arcs explode. Against mobile bosses or targets that displace frequently, the second hit can miss entirely, which means you lose both damage and the conversion value you were planning around. In stationary fights, this is fine. In messy fights, it becomes the mistake you feel immediately.

Her talents explain what you are supposed to do: trigger Tempestuous Arc’s Electrification consumption multiple times, then receive a teamwide Electric damage boost based on her Intellect for 15 seconds. With Potentials, the requirement drops and the payoff improves. That creates a clear rhythm: you build the buff, then you take the team’s burst window while it’s active.

Arclight performs best when your team plays around her flow instead of fighting it: keep Electric Infliction applied, convert at the start of the window, then use consumption-triggered follow-ups to keep SP and pressure high. If the team is not consistent about maintaining stacks or if the fight constantly breaks positioning, she becomes harder to pilot because her “second hit” and conversion timing stop lining up.
