Arknights Endfield Arcane Build Guide: Best Weapons, Gear Sets and Team Comps
This is the complete Arcane build guide for Arknights Endfield 1.4. Covers best weapons including her signature Solemn Phalanx, optimal INT and WILL gear sets with exact stat values, substat priority, 4 team compositions for every playstyle, potential investment breakpoints (P1 and P3 are priorities), and the damage rotation to maximize her Corrosion payoff.
Arcane Build Overview — INT vs WILL, Commit to One
Arcane's Array Arcana mechanic reads the balance between her Intellect (INT) and Will stats and determines her entire combat role. This is not a toggle you switch mid-battle — it is a build commitment decided by your gear, weapon, and substat choices.
INT Mode (INT ≥ Will): Nature DPS. Prioritizes frequent skill casts, AoE Arts damage, and Corrosion application. Run her as a primary or secondary damage dealer.
WILL Mode (Will > INT): Support/Control. Prioritizes enemy grouping, debuff spreading, and damage amplification for your team. Run her as a setup enabler.
According to GameMarket.gg's build guide, the single most important rule of building Arcane is: commit to one direction. A split INT/Will spread leaves her weak in both roles.
If you pulled Arcane and need Oroberyl for her signature weapon or materials, topping up through Topuplist gives you the Origeometry to finish her build fast.
Best Weapons for Arcane — Ranked and Compared
Arcane's weapon is the biggest single power source after her gear. Here is every option ranked with exact stats from Icy Veins' Arcane guide:
Signature vs F2P:
Solemn Phalanx is a meaningful jump for INT-mode DPS Arcane. Its Detonate effect directly amplifies her Corrosion payoff and Ultimate cycle.
Junction Point keeps her completely functional for free — it provides the same INT and UGE stats, just with a less powerful effect.
For WILL support builds, skip Solemn Phalanx entirely — its INT scaling pushes her into DPS mode. Use a Will-focused 5-star instead.
Weapon Enhancement Priority: Attribute (INT or Will) → Secondary Stat (UGE) → Skill → Level. Max the primary attribute first, then push UGE for faster Ultimate rotations.
Best Gear Sets — INT DPS vs WILL Support
Gear Set Comparison:
INT Mode — Hot Work Details:
The Hot Work set's 3-piece effect directly rewards Arcane's core loop. Every time she applies Corrosion — which she does constantly in INT mode through her Ultimate, Combo Skill, and Battle Skill — she gains a massive +50% Nature DMG buff. Pieces: Hot Work Exo-Rig (chest), Hot Work Hands PPE (gloves), Hot Work Insulation Slab (accessory). Use LYNX Slab as the off-piece.
WILL Mode — Eternal Xiranite Details:
Eternal Xiranite keeps Arcane's Will above her Intellect (confirming WILL mode) and rewards her frequent infliction stacking by amplifying the entire team's damage. Pieces: Eternal Xiranite Light Armor, Eternal Xiranite Wraps, 2× Eternal Xiranite Bracing Slab.
Stat and Substat Priority — How to Avoid a Split Build
This is where Arcane is won or lost. Your stat choices literally determine her role.
INT Mode Priority:
Intellect — keep ≥ Will at all times. This is non-negotiable; drop below and her kit flips to support.
Crit Rate → Crit DMG — standard offensive multipliers; Arcane's Corrosion ticks can crit.
Ultimate Gain Efficiency (UGE) — more Ultimates = more Corrosion applications = more +50% Nature DMG procs.
ATK% — scales all damage but lower priority than Crit and UGE.
WILL Mode Priority:
Will — keep > Intellect at all times. This is non-negotiable.
Ultimate Gain Efficiency — faster Ultimates = more Susceptibility stacks = more team buff uptime.
ATK% — secondary; Arcane's personal damage is not the priority in WILL mode.
Any support-oriented substat — healing bonus, energy regen, etc.
Common Mistakes:
Equipping INT gear on a WILL build — your Will must stay above Intellect. Double-check after every gear swap.
Trying to balance both stats — a 50/50 build is the worst Arcane. She is mediocre at DPS and mediocre at support.
Using Solemn Phalanx on WILL mode — the weapon's INT scaling will push her into DPS mode against your will.
If you need stamina refreshes to farm Hot Work or Eternal Xiranite gear, recharging at Topuplist keeps your gear farming going without downtime.
Best Team Compositions — 4 Proven Setups
Key Synergies:
Xaihi is nearly mandatory in Cryo teams — she provides Cryo and Nature amplification plus healing, directly scaling Arcane's Susceptibility debuffs.
Camille (Heat Vanguard) is the best SP battery for INT mode — faster SP = more skills = more Corrosion.
Liino (Phase 2 Electric Supporter) is the best healer for WILL mode — her team-wide ATK buff stacks multiplicatively with Arcane's DMG Taken debuff.
Potential Investment — Which Breakpoints Matter
Upgrade Priority: P1 → weapon → gear sets → P3 → P2+. P1 and P3 are the only potential breakpoints that fundamentally change how Arcane plays — P1 improves her rotation flow, P3 extends her most important debuff by 5 full seconds.
Arcane Damage Rotation — How to Maximize Corrosion
INT Mode Rotation:
Battle Skill (Jadecrushing Grid) → apply Nature Infliction to enemies in the array
Combo Skill (Yinglung Stance IV) triggers automatically when enemies have 1+ Nature Infliction stack → applies Imprisonment, increases Nature/Cryo DMG Taken
While Combo Skill is active, Basic Attack chain to build SP — finish the 5-hit combo for the Finisher, which restores SP and triggers bonus explosion damage on low-HP enemies
Ultimate (Gloompurge) when Corrosion stacks are at maximum → applies Corrosion to all enemies, triggers Hot Work +50% Nature DMG buff, fires up to 2 follow-up attacks from Finisher hits inside the array
Repeat: Battle Skill → Combo Skill → Basic Attack → Ultimate
WILL Mode Rotation:
Battle Skill → pull enemies into the array (crowd control), apply Nature Infliction
Combo Skill triggers on any Arts Infliction → adds +1 extra stack of matching element to enemies, increases Nature/Cryo DMG Taken
Switch to main DPS → let your carry capitalize on the grouped, debuffed enemy cluster
Ultimate when multiple enemies are grouped → adds +1 matching Arts Infliction stack to all inside range, further amplifying team damage

FAQ
Q: What is the best weapon for Arcane?
A: Type 42: Solemn Phalanx for INT DPS mode. Junction Point (Battle Pass) is the best F2P alternative. For WILL support, use a Will-focused 5-star — Solemn Phalanx pushes you into INT mode.
Q: What gear set should I use on Arcane?
A: Hot Work for INT DPS (Nature DMG +50% on Corrosion). Eternal Xiranite for WILL support (team DMG +16% on Susceptibility). Mordvolt Insulation or Tide Surge as bridge sets while farming.
Q: What is the most important stat for Arcane?
A: Intellect (if building INT DPS) or Will (if building WILL support). The stat that determines your mode must stay above the other at all times. After that: Crit Rate → Crit DMG → UGE → ATK%.
Q: What is Arcane's best team? A: INT mode:
Arcane + Tangtang + Xaihi + Perlica. WILL mode: Arcane + Yvonne/Last Rite + Tangtang + Xaihi. Xaihi is nearly mandatory for Cryo teams due to her Nature/Cryo amplification.
Q: Which potentials are worth investing in?
A: P1 (Combo Skill ×1.3 DMG + extra SP in INT / +6% Susceptibility in WILL) and P3 (Corrosion +5s duration). P2 is minor. P1 is the single best value breakpoint.
Q: What is the damage rotation for Arcane?
A: INT mode: Battle Skill → Combo Skill (auto-triggers) → Basic Attack chain (build SP, Finisher restores SP) → Ultimate at max Corrosion stacks → repeat.
Q: Can I use Arcane without her signature weapon?
A: Yes. Junction Point provides the same INT and UGE stats. The signature weapon is a meaningful upgrade for INT DPS but not required for either mode to function.
Q: What is the biggest mistake when building Arcane?
A: Splitting INT and Will equally. A balanced build leaves her weak at both DPS and support. Commit fully to one mode through your gear, weapon, and substat choices.
