Quick Guide
  • OverPeak Chapter 6 continues the main story after the NULLEM golem arc of Chapter 4.
  • Boss encounters in this chapter punish unprepared teams — bring burst damage and cleansing support.
  • Team setup: one tank, one healer, two damage dealers is the safest clear comp.
  • Resource management: conserve ultimate charges for phase transitions, not opening bursts.
  • Post-chapter rewards: chapter completion unlocks the next tier of gear progression.

Chapter 6 Overview & Story Context

OverPeak Chapter 6 picks up the momentum established in Chapter 4, where players confronted the NULLEM golem — a massive construct summoned from "no light" by an antagonist who had been waiting a long time to awaken their monster. That fight set the tone for the escalating difficulty curve that Chapter 6 inherits and pushes further.

If you skipped or rushed through Chapter 4, it is worth replaying it first. The NULLEM encounter teaches the phase-transition awareness and stagger-timing habits that Chapter 6 bosses demand. Watch the fight below to refresh the patterns:

Video Highlights:

  • The NULLEM golem awakening cinematic and the summoner's dialogue
  • Heavy, telegraphed melee swings that must be dodged, not tanked
  • The "no light" theme that ties into later chapter mechanics
  • Stagger windows after the golem's combo strings

Chapter 6 shifts from pure confrontation toward mixed objectives: escort-style segments, timed arena waves, and a multi-phase boss that tests both your gear score and your rotation discipline.

Before You Start

Recommended minimum power level is the Chapter 5 completion benchmark. Entering Chapter 6 under-leveled makes the mid-chapter wave segments significantly harder than the boss itself.

Chapter 6 Objectives & Encounter Breakdown

The chapter is structured around three major encounter blocks. Each one introduces a new pressure mechanic that later chapters assume you have mastered.

EncounterTypeKey MechanicDifficulty
Opening WavesTimed arenaAdd spawn timers, AoE overlap★★★☆☆
Mid-Chapter GauntletMixed objectivesEscort + elite interrupts★★★★☆
Chapter 6 BossMulti-phase bossPhase transitions, cleanse checks★★★★☆
MechanicWhat It DoesCounter
Wave SurgeSpawns grouped adds every 30sSave AoE ultimates for surge windows
Gloom MarkDebuff that stacks on hit targetsBring a cleanser or immunity skill
Phase ShiftBoss resets aggro and buffs itselfRe-position, stagger burst for after
Common Mistake

Do not burn ultimate charges in the first 20% of the boss health bar. Both major damage checks occur after phase transitions, and an empty ult bar at those moments is the most frequent cause of wipes.

Best Loadouts & Team Comps

Team composition flexibility matters more in Chapter 6 than raw damage. These three setups all clear the chapter reliably, with different trade-offs.

Balanced Standard

  • 1 Tank / 1 Healer / 2 DPS
  • Safest for first clears
  • Forgives positioning errors
  • Slower kill times

Burst Focus

  • 1 Tank / 1 Healer / 3 DPS
  • Fastest phase pushes
  • Demands tight dodge timing
  • Best for geared players

Sustain Grind

  • 2 Healers / 1 Tank / 2 DPS
  • Excellent vs. Gloom Mark
  • Very high consistency
  • Risk of hitting enrage timers
RolePriority StatWhy It Matters
TankHP / DefenseSurvives heavy telegraphed swings
HealerCooldown reductionKeeps cleanse available every surge
DPSBurst damageBreaks phase checks before resets
Gear Check

Before the boss, confirm every party member's gear matches the Chapter 5 reward tier or better. Chapter 6 stat requirements scale noticeably compared to earlier chapters.

Step-by-Step Clear Route

1

Prep Your Squad

Verify gear tiers, stock consumables, and assign interrupt roles before entering. Confirm your healer has a cleanse equipped for Gloom Mark.

2

Clear the Opening Waves

Hold AoE ultimates until Wave Surge windows. Focus the elite add first — it applies the stacking debuff that punishes AoE-only strategies.

3

Survive the Gauntlet

During the escort segment, keep the protected target ahead of spawn timers. Interrupt elite casts on cooldown; missed interrupts add minutes to the run.

4

Boss Phase One

Dodge telegraphed swings, manage stacks, and push to the first transition at a steady pace. Do not overspend ultimates here.

5

Boss Phase Two & Finish

After the Phase Shift buff, unload saved burst, cleanse Gloom Mark promptly, and finish the kill to unlock Chapter 7 content and the next gear tier.

Pacing Advice

Treat the chapter as an endurance run. Consistent execution through the gauntlet matters more than optimization — most failed runs collapse before the boss room, not during it.

Completion Goals & Rewards

Full chapter completion unlocks several progression milestones. Track them with this checklist:

Chapter 6 Completion Checklist:

  • Clear all three encounter blocks
  • Defeat the Chapter 6 boss without party wipes
  • Reach the next gear progression tier
  • Unlock Chapter 7 story access
  • Cleanse 10 Gloom Mark stacks in one run

Once cleared, replay earlier chapters (including the Chapter 4 NULLEM fight) with your upgraded gear to farm resources efficiently before pushing forward.

FAQ

Q: Is OverPeak Chapter 6 harder than the Chapter 4 NULLEM boss fight?

Yes, generally. Chapter 6 assumes you have internalized the phase-transition and stagger habits taught by the NULLEM golem, then adds debuff management and timed wave pressure on top of a multi-phase boss.

Q: What is the minimum power level for Chapter 6?

The Chapter 5 completion benchmark is the recommended floor. Entering under-leveled makes the mid-chapter gauntlet the hardest part of the run rather than the boss.

Q: Which team composition is best for a first Chapter 6 clear?

The balanced 1 tank / 1 healer / 2 DPS setup is the safest choice. It forgives positioning mistakes and keeps cleanse coverage consistent through the Gloom Mark checks.

Q: Should I use ultimates early in the Chapter 6 boss fight?

No. Both major damage checks happen after the Phase Shift transition. Saving your burst for post-transition windows is the single biggest improvement most players can make.
