"A contained, previously inert portal sealed in the Dungeon"

The Ceaseless Void is a post-Moon Lord boss and is one of the Rune of Kos bosses. It drops Dark Plasma, which is a crafting material used to craft the Cosmic Worm.

Spawn

The Ceaseless Void does not spawn on its own and requires the player to summon it by using the Rune of Kos in the Dungeon.

Behavior

Upon being summoned, the Ceaseless Void is completely invincible to damage, and 11 Dark Energies are spawned in a 3-armed star formation centered on the boss. The Dark Energies will oscillate back and forth relative to the Ceaseless Void while also rotating around it in a clockwise manner. The Ceaseless Void itself will initially hover directly above the player, but will cycle through 8 different positions around the player over time, moving one position counterclockwise every 8 / 6 / 4 seconds.

When the total HP of Dark Energies reaches 50%, all Dark Energies despawn as the Ceaseless Void becomes vulnerable, positions itself near the player, and begins sucking in both nearby players and a 4-armed spiral of invincible Dark Energy Balls that converge on it, with the spiral growing in speed and density as the attack goes on. At the start of the attack, it will also summon two Laser Portals that orbit around the player, firing two sets of slow Laser Beams towards them. If the player attempts to flee from it, the Ceaseless Void will stop the attack and quickly move near the player before resuming.

The Ceaseless Void will go invulnerable and repeat the above two phases at specific health intervals, summoning increasing amounts of Dark Energies in more complex formations each time while increasing the amount of damage that must be dealt to them to progress.

At 70% HP, summons 14 Dark Energies in a 4-armed star shape, with the phase ending once their total HP reaches 35%.
At 40% HP, summons 17 Dark Energies in a 5-armed star shape, with the phase ending once their total HP reaches 25%.
At 10% HP, summons 20 Dark Energies in a 6-armed star shape, with the phase ending once their total HP reaches 20%.

When the last group of Dark Energies is defeated and the Ceaseless Void uses its vacuum attack, it will be invulnerable as its health slowly depletes, forcing players to survive for 15 seconds as its suction force gradually increases in power. After 15 seconds, the boss will implode, leaving its loot behind and despawning all of its projectiles.

In Expert Mode

Changes position in its invincible phase every 6 seconds.
Dark Energies follow a curving path, making them harder to avoid.
Each formation of Dark Energy now has 4/5/6/7 arms and 14/17/20/23 Dark Energies.
Suction force from the vacuum attack is stronger.
Below 70% HP, the vacuum attack periodically sucks in two extra Dark Energy Orbs from opposite sides once the Dark Energy spiral is fully formed.

In Revengeance Mode

Changes position in its invincible phase every 4 seconds.
Dark Energies move faster.
Suction force from the vacuum attack is even stronger.
Each formation of Dark Energy now has 5/6/7/8 arms and 17/20/23/26 Dark Energies.
Three Laser Portals are summoned instead of two.

In Death Mode

Each formation of Dark Energy now has 6/7/8/9 arms and 20/23/26/29 Dark Energies.

On the For the worthy seed

Is 15% faster.
Dark Energies are 50% smaller.
Spawns twice the amount of Dark Energies.

Summons

Resistances

Dark Energies take reduced damage from most non-minion piercing projectiles. Each hit decreases the damage of the next hit by 12%, until the eighth hit onwards which deal 20% of original damage.
Dark Energies also take 50% damage from true melee hits.

Notes

Dark Energies are harmless but invincible for 2 seconds after spawning.

Tips

For more elaborate strategies on defeating the Ceaseless Void, including weapon and arena recommendations, see Guide:Ceaseless Void strategies.

Make use of Gravity Normalizer Potion, as it gives immunity to the Distorted debuff. This makes dodging and staying alive considerably easier and makes taking a hit less annoying.
Bring high damage weapons especially if they have area of effect capabilities, as they can easily clear out the Dark Energies.
Keep moving in a spiral pattern when the Ceaseless Void is vulnerable or using its last attack, as the converging Dark Energy spiral increases in intensity the longer the attack is ongoing.
The Elemental Disk can produce many splitting projectiles, allowing it to easily take out the swarms of Dark Energies.
The Elemental Eruption will take out the Ceaseless Void incredibly quickly, but is not very strong against its minions.
If Storm Weaver has been defeated, The Storm is very effective both versus the Ceaseless Void and its Dark Energies.
The Starfleet can deal massive damage while the Ceaseless Void is vulnerable, sometimes skipping phases or killing it instantly. If aimed well, it can dispatch Dark Energies in a single shot.
The Telluric Glare is very useful for the Dark Energies and can skip sometimes 1 or 2 phases.
The Nuclear Fury does excellent damage to clumped together Dark Energies and does decent damage to the Ceaseless Void itself.
The Blissful Bombardier is a good choice against the Dark Energies for its homing and area damage. Its decent fire rate can also deal with the Ceaseless Void itself pretty easily.
The Ark of the Elements is still a good choice, as it homes in on the Dark Energy and the Ceaseless Void.
The Divine Retribution's storm of spears will deal extreme damage to the Ceaseless Void when it is vulnerable.
Single-target minions struggle against the Ceaseless Void due to its many minions. Use summons with an area of effect damage such as the Stardust Dragon Staff or Elemental Axes instead. The Profaned Soul Artifact is also recommended.
The Molten Amputator's explosions and lava globs can deal with grouped Dark Energies very rapidly.
If the player is having a very hard time making space in the Dungeon, they could lure the Ceaseless Void out of the Dungeon if they can handle it being enraged. This trades a lack of space for a large increase in speed for the Ceaseless Void.
- The player can make use of Asphalt Blocks to move faster or blocks like Frozen Slime Blocks and Ice Blocks to conserve momentum.
While the Ceaseless Void can be fought before any other post-Moon Lord boss, it is not recommended to fight until Providence is defeated, the many projectiles and Dark Energies make this fight very challenging.

Trivia

The Ceaseless Void's theme is a segment from Servants of the Scourge, which was composed by the artist DM DOKURO.
- This theme contains a motif from The Devourer of Gods' theme.
- If the Calamity Music add-on mod is disabled, Boss 3 will play instead.
The Ceaseless Void, along with the Storm Weaver and Signus, can be summoned right after the Moon Lord is defeated, as their summoning item only requires Solar Fragments, Luminite Bars, and Unholy Essences.
Prior to the 1.5.0.001 update, The Ceaseless Void originally had the lowest health out of all bosses, but this weakness was nullified with having the highest DR.
If the Boss Checklist Mod is installed, its unique despawn message will be "The ancient spatial rift slips away to places unknown."
