Arknights: Endfield Act 2 Chapter 6-7 Combat and Boss Guide

To clear main story Act 2 (Chapters 6 and 7) in Arknights: Endfield, switch from automated combat to manual team control, use terrain cover against ranged fire, and build a party capable of rapidly filling enemy stagger meters. If incoming enemy damage overwhelms your team despite clean skill timing, level up your primary damage dealer's weapons and accessory sets to clear the stage's stat requirements.

Environmental Positioning and Mobility

The encounter spaces in Chapters 6 and 7 feature complex layouts with ranged enemy line-of-sight and ground-targeted area-of-effect (AoE) attacks. Standing in open terrain wastes ability cooldowns on forced healing and limits offensive movement.

Before triggering combat or committing to an engagement, apply these positioning priorities:

• Locate high-ground markers and mobility pads: Identify high-ground positions or tactical movement pads near the encounter area to quickly reposition the squad when enemies initiate wide-area attacks.
• Use terrain cover: Position ranged units behind physical terrain barriers to break line-of-sight from stationed ranged enemies.
• Save mobility skills for repositioning: Reserve movement-based mobility skills to dodge heavy telegraphed attacks or close distance instantly after a boss teleports, rather than using them for basic distance closing.

Team Synergy and Stagger Execution

Boss encounters in late Act 2 feature elevated defense values and staggered vulnerability windows. Success depends on breaking enemy defenses with specific utility operators rather than relying purely on passive single-target damage.

Ability Cooldowns and Skill Rotations

Mismanaging support skill uptime leaves the team vulnerable during late boss phases. Cycle team abilities in a set order to maximize damage output during vulnerability states while maintaining survival uptime:

1. Activate support buffs: Apply defensive and offensive stat buffs from support units before triggering offensive skills.
2. Apply damage-over-time (DoT): Cast DoT abilities immediately prior to entering or triggering a boss stagger state so the tick damage overlaps with maximum buff uptime.
3. Unload primary offensive ultimates: Execute single-target burst skill rotations while the boss is staggered and defensive stats are temporarily lowered.
4. Sync healer recovery: Time your healer’s active recovery skill with predictable heavy boss strikes to stabilize team health without losing offensive pace.

Overcoming Gear Progression Walls

Chapters 6 and 7 act as progression checks for squad gear levels. If clean manual execution still results in continuous team wipes, evaluate your party's base stats and execution style:

• Upgrade primary carry gear: Prioritize flat stat gains by upgrading the weapon levels and accessory sets of your main carry unit to meet the incoming damage threshold.
• Use manual target control: Manual control allows you to manually interrupt enemy spell casting animations and redirect target aggro away from low-health support units, bypassing strict gear requirements that automated combat cannot compensate for.
