Void Jailer

The  is a monster added in the Survivors of the Void update, and is part of the monster family.

Environments
Like other enemies, Void Jailers can spawn on any map if spawned in a Void Seed.

Skills & Behavior
The Void Jailer is one of the more dangerous Void enemies due to its high burst damage and ability to grab and draw in the player at a distance.

Any single instance of damage that deals more than 15% of the Void Jailer's total health will stun it and interrupt its attacks or movement.

Primary: Void Darts
The Void Jailer charges his left arm for 1 second (scales with attack speed) and fires a volley of 12 Void Darts in a shotgun-like burst. The projectiles originate from a random point within a circle in front of the Jailer, meaning the bullets begin with some amount of spread between each other rather than from a single origin. Each projectile moves at 100m/s for 2 seconds and deals 200% damage with a proc coefficient of 1.0, the victim in the process for 2 seconds. Getting hit with all projectiles at once can deal a devastating blow, especially in the late game.

The individual darts can be blocked by.

This skill has an end lag of 3 seconds, but the Void Jailer can activate the same skill after only 2 seconds. Both of these durations scale with attack speed.

This skill has a cooldown of 4 seconds and 3 charges. The cooldown starts the moment the projectiles have been fired and will be reset if this skill is activated again. This means a charge will only be replenished if this skill is not used for 4 consecutive seconds.

Secondary: Nullifying Pull
The Void Jailer charges his right arm for 1 second (scales with attack), which causes a long tube of purple particles to getting sucked towards it. Upon launching the attack, it searches for a target that is within a 10° field of view and up to 100m away from the Void Jailer, prioritising targets that are as close to the Jailer's aiming direction, even if there are further away. The attack deals 30% damage with a proc coefficient of 1.0, inflicts for 2 seconds, and pulls the target towards the Void Jailer. The pull has the potential of pulling the target into a swarm of enemies, or even towards a cliff where fall damage can be dangerous. However, the victim can still use their skills and jump to cancel any fall damage while Nullified.

This skill has a cooldown of 10 seconds.

Death: Seeking Implosion
Unlike the and 's black hole, the Jailer's death fires a moving variation of the black hole that chases after a randomly selected victim, and implodes after 5 seconds of travel in a 6m radius. The death orb moves slowly at 10m/s, which makes it possible to outrun at the default sprint speed of most survivors.

Behaviors

 * 1) Use secondary: the Void Jailer must be within 80m from its target, have line of sight, and have less than 80% health.
 * 2) Use primary and chase: the Void Jailer must be within 45-80m from its target and have line of sight. This behavior is active for 3 seconds.
 * 3) Use primary and strafe: the Void Jailer must be within 1-45m from its target and have line of sight. This behavior is active for 3 seconds. Note that due to the Void Jailer's model size and its internal origin location, being more than 1m away from it is always guaranteed.
 * 4) Chase: no requirements.

Tips

 * If the player has the, activating while being pulled will prevent the player from being pulled further. However, they will still be Nullified unless it is activated beforehand.
 * When Nullified, there is not much that the player can do outside of killing the Jailer before it fires its primary attack, which leaves the player with about 3 seconds to get out of the black hole.

Trivia

 * In keeping with the deep-sea theme of the Void and the monsters related to it, the Void Jailer's visual design seems to draw inspiration from ocean life, especially crustaceans and other arthropods. Jailers in particular incorporate several elements from shrimp, particularly pistol shrimp (Alpheidae), such as the long, thin head and antennae, the asymmetrical arms, and small, spindly legs.
 * Additionally, pistol shrimp have a specialized hunting adaptation: by snapping shut its claw at high speed, a pistol shrimp can depressurize a small pocket of water so much that it creates a bubble of vapor, known as a cavitation bubble. Since the water pressure around the bubble is so much higher than inside it, the bubble rapidly collapses and generates a shock wave powerful enough to stun or kill the shrimp's prey. It is possible that the Jailer launching an imploding void bubble at its target is in reference to this behavior.
 * The line "deep, deeper, yet deeper" in the lore may be a reference to the infamous Entry Number 17 from Undertale, where a similar line of "DARK DARKER YET DARKER" is written in Wingdings font.
