The Void Ark represents Final Fantasy XIV’s inaugural 24-player raid introduced in the Heavensward expansion, continuing the tradition established by the Crystal Tower series from A Realm Reborn. This massive cooperative encounter provides exceptional farming opportunities for dedicated dungeon runners seeking challenging group content. Understanding the intricate mechanics and coordination requirements separates successful runs from frustrating wipes.
Accessing this formidable raid requires meeting specific prerequisites: character level 60 minimum, average item level 175 or superior gear, and completion of the “To Rule the Skies” questline. The quest giver resides in Utata within The Sea of Clouds region, with “Sky Pirates” serving as the mandatory prerequisite. The raid composition follows a structured 1:2:5 ratio across three alliances, totaling 3 tanks, 6 healers, and 15 DPS players working in coordinated harmony.
Proper preparation significantly enhances your raid experience. Ensure your gear meets minimum requirements, consumables like stat-boosting food and potions are stocked, and you’ve familiarized yourself with your job’s rotation.

Cetus presents a fundamental DPS check encounter that tests raid-wide damage output and positional awareness. The boss deploys multiple hazardous mechanics simultaneously, requiring constant environmental scanning and quick reaction times from all participants.
Throughout the engagement, Cetus randomly deposits bubbles that generate persistent area-of-effect zones on the battlefield. These require careful navigation throughout the fight. The creature executes body slam attacks targeting random locations and unleashes room-wide electrical discharges that mandate close proximity to the boss for damage mitigation.
Add management constitutes a critical component of this encounter. Primary adds demand immediate elimination, while secondary smaller adds employ long-range charge attacks. Players targeted by these charges should immediately move into melee range to prevent widespread raid damage.
During add phases, Cetus takes flight and traverses the arena, deploying massive AoE bubbles that inflict severe damage and knockback effects. The climax occurs when Cetus positions centrally, stunning the entire raid and dividing the party. An impassable barrier materializes while four linked adds spawn externally with one core internally. Teams face an urgent timer to eliminate all external and internal targets simultaneously to avoid collective knockout.
Irminsul and Sawtooth
Irminsul and Sawtooth
This twin boss confrontation often confuses newcomers due to its complex tank coordination and environmental mechanics. Designate one tank to maintain aggro on Irminsul while another handles Sawtooth, with a third tank ideally managing spawned adds. The shifting soil mechanics beneath adds represent the encounter’s primary challenge.
Eliminate adds before soil consumption or reposition them away from hazardous zones. Each consumed add grants the boss points; reaching the maximum point threshold triggers an immediate raid wipe. Avoid being devoured, as this inflicts a plant-based infection that impairs character control and spreads through short-range cone attacks to nearby allies.
Irminsul employs circular area attacks while Sawtooth periodically executes tail swipes. Random raid members receive yellow circle markers with extensive AoE radii, creating tethers that bind adjacent players and disable their actions. Break these constraints by having unaffected members physically intercept the tether lines.
The most dangerous mechanic occurs when Sawtooth becomes enveloped in crimson electricity during an extended cast. Every participant MUST immediately seek cover behind Irminsul, breaking line-of-sight with Sawtooth to evade this instant-kill ability.

Cuchulainn’s multifaceted encounter introduces numerous simultaneous mechanics that demand precise execution. All participants begin with an incurable bleeding debuff that persists throughout the engagement. Position yourself behind the boss to avoid corrosive bile, which discharges moderate frontal area damage.
The boss summons five statues that escalate bleeding stacks to five if not promptly destroyed. Failure to eliminate statues before their detonation triggers catastrophic explosions. He also projects extensive poison circle AoEs, making elevated platforms hazardous positioning during certain phases.
Environmental awareness proves crucial when Cuchulainn saturates the ground with green coloration. During this phase, immediately relocate to raised platforms to avoid devastating damage. Slime adds spawn on these platforms, which the boss attempts to consume. The current aggro holder should reposition mobs away from Cuchulainn’s consumption cone. Each successfully consumed add provides the boss with a stacking damage enhancement buff.
Following this sequence, Cuchulainn casts a raid-wide AoE requiring healers to prepare area healing abilities. Tentacle slams necessitate positioning between tentacles to avoid corruption damage and knockback effects. Black Lung casts occur twice, generating orbs that must be collected by all members to prevent binding explosions. For detailed damage optimization approaches, reference our weapon and ability guides.
Scathach delivers a comparatively straightforward engagement with clearly telegraphed mechanics. She employs cleave attacks and circular area effects designated “Abyssal Sickle.” The boss periodically leaps airborne, targeting random members with substantial grey AoE circles featuring directional arrows.
When targeted, consolidate the entire raid on the marked player to distribute and mitigate incoming damage. She also casts raid-wide petrifying AoEs requiring players to avert their gaze from the boss. Additional mechanics include dual rectangular line attacks with safe gaps positioned on opposing sides.
Aerial assaults create multiple large circular AoEs that inflict massive damage upon contact. At approximately 70% and 40% health thresholds, Scathach divides into three entities, each focusing a tank from separate raid parties.
Strategic waymark placement on opposite map edges prevents tether connections between split forms. Proximity between divided entities generates stacking defense buffs, dramatically increasing encounter difficulty. The primary body continues casting petrification abilities during division phases. Failure to eliminate all forms within the time constraint results in raid wipe. Throughout the engagement, she summons additional adds during two distinct intervals.
Optimizing your Void Ark performance requires understanding subtle mechanics and coordination nuances. For tank assignments, ensure clear communication regarding boss positioning and add management responsibilities. Healers should coordinate cooldown usage for predictable heavy damage phases.
Common mistakes include mismanaging Cetus’s separation phase, failing soil mechanics against Irminsul and Sawtooth, and improper orb collection during Cuchulainn’s Black Lung casts. Positional errors during Scathach’s splitting phase represent another frequent failure point.
Efficiency strategies involve assigning specific DPS to add duty during Cetus, designating interrupt roles for Irminsul and Sawtooth, and establishing clear platform assignments for Cuchulainn’s environmental phases. Communication through markers and quick chat commands significantly enhances coordination across alliances.
Advanced players can optimize clear times by pre-positioning for mechanic transitions, utilizing job-specific utility abilities strategically, and maintaining optimal damage rotations during movement-heavy phases.
