The Seven Deadly Sins: Origin Demonic Beast Akumu Boss Guide

To achieve scores exceeding 600k against Demonic Beast Akumu in the Knighthood Boss challenge of The Seven Deadly Sins: Origin, you must reserve your primary carry's burst damage for the boss's stagger phase. Akumu maintains high innate damage reduction and casts defensive barriers during neutral combat. Maximizing your point total requires chipping down Akumu's stagger gauge with your sub-DPS, applying team buffs immediately before the gauge empties, and unloading your carry's ultimate abilities while the boss is immobilized.

Scoring Mechanics and Break Multipliers

Knighthood Boss scoring is determined by total damage output within the time limit, clear speed, and party health preservation. Taking avoidable damage directly lowers your score.

Akumu frequently generates shields that absorb incoming damage. Attacking through these barriers without depleting the stagger gauge wastes valuable damage potential. Pushing Akumu into a groggy break state temporarily removes all shields, cancels incoming attacks, and applies a major damage vulnerability multiplier. Because the multiplier only lasts until the break gauge resets, your entire team rotation must align around this specific window.

Team Composition and Stat Priorities

Structure your four-character party to balance continuous shield-stripping, buff uptime, and concentrated burst damage:

Role	Primary Responsibility	Priority Stats
Main DPS Carry	Delivers burst damage and ultimates during stagger	Crit Rate (60%+ base), Crit DMG, Elemental ATK
Sub-DPS / Breaker	Depletes shields and applies off-field pressure	Attack Speed, Stagger Value, Energy Recharge
Offensive Buffer	Amplifies attack power, critical output, and damage scaling	Buff Duration, Skill Haste, Energy Recharge
Defensive Utility	Cleanses debuffs, heals, and prevents arena interruptions	HP, Cooldown Reduction, Elemental Resistance

Build your primary DPS carry to match Akumu's active elemental weakness. Aim for at least 60% Critical Rate before external buffs to ensure your burst hits connect reliably during vulnerability windows. Prioritize Critical Damage over flat Attack on gear, as percentage multipliers yield higher returns against broken targets.

Supports and sub-DPS units must stack sufficient Energy Recharge. If your buffers cannot cast their ultimate abilities before Akumu enters a break state, your primary carry will miss peak damage windows.

Engagement Rotation and Burst Timing

Follow this sequence to ensure your highest-damaging attacks land while all party buffs and boss vulnerabilities are active:

Strip the Stagger Gauge: Open the fight using your sub-DPS and support skills. Attack Akumu's shields continuously to deplete the stagger bar. Hold your main carry's high-cooldown skills and ultimate ability during this phase.
Pre-Cast Support Buffs: Watch Akumu's stagger meter. Once 10% to 15% of the gauge remains, cycle through your supports to cast attack buffs, elemental amplifiers, and defense-shredding debuffs.
Trigger the Break State: Strike with a high-stagger ability to empty the remaining meter. Akumu will drop into an immobilized groggy state.
Execute the Carry Burst: Immediately swap to your primary DPS. Cast your signature skills followed by your ultimate ability to take full advantage of the active buff timers and vulnerability multiplier.
Reset and Recharge: Back off to mid-range as Akumu recovers. Reapply off-field abilities, regenerate energy, and prepare for the next stagger cycle.

Surviving Boss Telegraphs

Sustaining hits incurs point penalties and interrupts your skill rotation. Watch for these visual cues to maintain maximum scoring potential:

Overhead Slam: Akumu raises its limbs and projects a narrow rectangular red path. Dodge laterally rather than backward to remain in melee range without taking damage from the shockwave.
Radial Ground Cleave: A large circular red zone appears beneath Akumu. Dash outward immediately. Attempting to finish an attack string during this windup leads to a knockdown and wasted buff durations.
Targeted Ranged Volleys: When Akumu leaps backward, it fires a sequence of tracking projectiles. Sprint diagonally across the arena to outrun the tracking arc instead of depleting all your stamina on consecutive dodges.

Always maintain at least one reserve dodge charge. Running out of stamina during Akumu's wide-area attacks leaves your characters vulnerable to knockdowns, resulting in severe score penalties.
