Arknights Endfield Lifeng Build & Analysis

Lifeng is a 6★ Guard in Arknights Endfield who plays the “bridge” role in a Physical team: he brings control, grouping, Link, and a very specific way to apply Physical Susceptibility. He is not a pure hypercarry — he’s the operator that makes the team’s burst windows happen on time, and makes crowded fights stop being annoying.

If you are comparing Lifeng to other operators or trying to understand where he 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

Lifeng’s whole identity is in one sentence: he applies Physical Susceptibility to targets that are not yet Vulnerable. That’s the mechanic. Everything else — Knock Down, grouping, Link — exists to help you exploit that mechanic without the fight turning into a mess.

Turbid Avatar is where the friction starts. The Susceptibility check happens on the last hit of the animation, and it only applies if the target has no Vulnerability stacks (or, with Potential I, no more than 2). So if your team “tags” the target too early, or your own first hits apply Vulnerability first, the debuff window disappears. You don’t get a partial reward. You just get a slam and move on.

That’s why Lifeng feels clunky in fast fights: the condition is strict, and the payoff is delayed. You’re watching the enemy state while your character is still locked in the swing. When it works, it’s clean — you land the last hit on a fresh target, Susceptibility goes up, and now your DPS can dump a rotation into a real multiplier.

Aspect of Wrath is the follow-up tool. It triggers off Final Strike on a target that already has Physical Susceptibility or Breach, and it grants Link. That Link matters because Heart of the Unmoving can consume it for extra damage, and because Link lets you set up bigger windows without forcing your main carry to change their rotation.

Heart of the Unmoving is the “crowd fix.” It hits, knocks down, pulls enemies, then hits again if they stayed in the zone. In practice, that’s Lifeng telling the map: “Stop scattering.” If you’re farming or fighting dense packs, this is the difference between hitting one enemy and hitting all of them. If you consume a Link, you get the additional massive hit — and that’s your reward for running the sequence correctly.

Verdict: Lifeng is a hybrid support/sub-DPS who makes Physical teams feel more complete: grouping, CC, Link, and a powerful but strict Susceptibility application. The cost is execution. His best debuff only lands inside a tight window, and that window happens at the end of an animation lock. If your team can respect the timing, he’s a premium bridge unit. If the fight is too chaotic, he’ll still control and group — but you’ll miss the part you brought him for.
