Void Fiend

Escaped : ..and so it comes... for all of us.
Vanished : ...and so it vanished, a whisper in the darkness.

The **Void Fiend** is a playable character in Risk of Rain 2, added in the *Survivors of the Void* expansion.

It is an eldritch, void-mutated monstrosity capable of harnessing the Void as a lethal weapon. In battle, its corrupted energy builds up until it reaches a critical point, unleashing its full power and transforming it and its abilities into more aggressive versions.

Its name is stylized in-game as「V??oid Fiend』.

Completing the Dragged Below challenge will unlock Void Fiend as a playable survivor.

## Skills

Passive

 Description
 * Stylized in-game as 『V??oid Co??rruption】.
* The Void Fiend's Corruption is visible as a circular gauge, ranging from 0-100%.
* The  buff indicates when the Void Fiend is in its corrupted state and grants 100 armor.
* While the Void Fiend is uncorrupted, the Corruption gauge fills over time. While it is corrupted, the inverse is true, and Corruption depletes over time.
* Taking damage, landing critical strikes, and possessing void items builds Corruption, while healing will reduce Corruption.
* For each void item the Void Fiend possesses, its minimum Corruption level is increased by 2%. This makes it corrupt itself faster, but does not make its corrupted duration shorter. Instead, the corruption depletes at a slower rate the more void items it possesses.
	+ Minimum Corruption can be increased to 100%, which permanently locks the Void Fiend into its corrupted state.
	+ Increasing it beyond 100% results in it flickering between the minimum value and 100% with no effect on gameplay.
* Corruption is reset to minimum upon advancing to the next stage.
* Receiving any healing reduces corruption percentage in either state. With enough passive healing through items its possible to avoid being corrupted without using Suppress, or simply be unable to be corrupted without instantly returning to a normal state.
* When transforming, the Void Fiend gets 0.5 seconds of invincibility and the cooldowns of its abilities are reset.

 Proc Coefficient
 Description
 * Description clarification: Fires a laser that ticks approximately 8 times per second for 250% of Void Fiend's damage per shot.
	+ Increasing Void Fiend's attack speed increases the number of ticks per second.
* Has no aim assist, unlike the uncorrupted version.
* Pierces through enemies and terrain with a range of 40m.

* Can sprint while charging (start charging and then sprint, needs to be repeated for every attack).
* Takes about 1s to charge at base attack speed.
* A fully charged Flood can be held indefinitely, and Flood's cooldown begins once it has been fully charged.
* Pushes Void Fiend and enemies back when launched, pushing it further with a greater charge or while airborne.

 Cooldown
 Proc Coefficient
 Description
 * Unlike the uncorrupted version, it does not need to be charged at all and fires immediately.
* Pushes Void Fiend back, but does not push enemies back.
* Unlike the uncorrupted version, the projectile is affected by gravity and arcs downward over long distances.

Utility

 Cooldown
 Description
 * Stylized in-game as 「?Tr?espass】.
* Can be used while channeling Suppress.
* Neither the invulnerability or the movement can be cancelled early, except by transforming into its corrupted form.
* Leaves the Void Fiend with some upward momentum when exiting the skill.
* The distance traveled and ending momentum scale with movement speed.
* The invulnerability completely removes Void Fiend's hitbox.

 Cooldown
 Description
 * Has a shorter duration than the uncorrupted version, giving a narrower window of invincibility.
* The distance traveled and ending momentum scales with movement speed.
* Similar to , Corrupted Trespass moves the Void Fiend horizontally but not vertically.

Special

 Description
 * .
* Stylized in-game as 【Sup??ress』.
* Takes about 1s to channel at base attack speed.
* If Corruption reaches 100% while channeling, the Void Fiend stops channeling and transforms into its corrupted form.
* If Void Fiend's minimum Corruption from gathering void items is 25% or higher, this can be used infinitely.

 Description
 * .
* Has 2 base charges.
	+ Charges are not restored until the Void Fiend becomes uncorrupted and then becomes corrupted once more.
* Unaffected by cooldown-resetting effects such as the .
* If Corruption reaches its minimum value while channeling, the Void Fiend stops channeling and transforms into its uncorrupted form.
* The self-inflicted damage can also be .

## Behaviors

*For an explanation of how these behaviors are implemented read about Enemy AI. This section only applies when the character is controlled by AI.*

1. **Use Primary (Corrupted Drown)**: Void Fiend must be within 15m from the target and have line of sight.
2. **Use secondary (Flood)**: Void Fiend must be within 10-30m from the target and have line of sight. This behavior is active for 2 seconds, which means it will be charged for its duration and released at the end of it.
3. **Use secondary (Corrupted Flood)**: Void Fiend must be within 30m from the target and have line of sight.
4. **Use utility (Trespass)**: Void Fiend must be within 5-40m from the target and will sprint after its activation.
5. **Use utility (Corrupted Trespass)**: Void Fiend must be more than 40m from the target and will sprint after its activation.
6. **Use special (Suppress)**: Void Fiend must have less than 50% health and will sprint after its activation.
7. **Use special (Flee and Heal)**: Void Fiend must have less than 25%. The behavior is active for 1 second and Void Fiend will sprint for its duration.
8. **Use primary (Drown)**: Void Fiend must be within 5-50m from the target and have line of sight.
9. **Chase while using primary (Drown)**: no requirements as long as Void Fiend is not corrupted. It is observed that if Void Fiend is right next to the player, they will not use the primary but only continuously rotate around in an effort to get even closer. As such, the character can find itself in a locked state where it cannot use any other ability until its target has gained enough distance or the corrupt meter fills up and using Corrupted Drown becomes valid.
10. **Chase while using primary (Corrupted Drown)**: Void Fiend must be more than 5m from the target. Void Fiend will attempt to sprint, but will constantly toggle between sprinting and use the primary. Technically because of the very first behavior, this will only be selected if the target is more than 15m away.
11. **Flee while using primary (Drown)**: Void Fiend must be within 5m from the target. This behavior will never be selected

## Tips

* Although it comes at the cost of Suppress's ability to control Corruption levels, acquiring  allows Corrupted Drown to set up a large number of  stacks due to its high rate of fire.
* Using Suppress to manage corruption throughout a stage means that the player can reach 100% Corruption right when activating the Teleporter.
* Drown has an extremely long range when uncorrupted, allowing Void Fiend to attack from very safe distances. Corrupted Drown, in contrast, has an extremely *short* range but fires more quickly, encouraging aggression.
* The inherent aim assist of Drown can be very helpful for dealing with , as can the area-of-effect damage of Corrupted Drown, Flood, and Corrupted Flood.
* Releasing a fully charged Flood in midair while moving backwards can be a good way to put distance between Void Fiend and enemies. Firing a fully charged shot will also launch the player upwards, which can be very useful for reaching higher spots or dodging.
	+ This can be used to even greater effect with Corrupted Flood, as having stacks of  can launch Void Fiend across the map.
	+ Both Corrupted Flood and Flood can be used to prevent fall damage when shot at the ground right before landing.
	+ Using this method, firing multiple charges of Corrupted Flood at the ground can briefly stall Void Fiend in the air.
* Unused charges of Flood will reset after changing between forms.
* Since it deals more than 400% base damage, Flood can trigger , , and  even when not fully charged.
* The channel time of Suppress is affected by Void Fiend's attack speed. If attack speed is lowered too much, the delay can make it difficult to manage Corruption.
	+ At default attack speed, Void Fiend accumulates an extra 3% corruption in the 1 second it takes for the skill to execute. Activating Suppress after 95% will still result in the Void Fiend becoming Corrupted.
* Interacting with a Shrine of Blood or Void Cradle increases Void Fiend's corruption, allowing it to use Suppress to quickly recoup some of the lost HP.
	+ The player should be mindful of activating either of these objects when enemies are near. Interacting with these objects can put Void Fiend into its Corrupted form, preventing it from healing with Suppress.
* Although Drown cannot be used while Flood is charging, Flood can be charged while Void Fiend is sprinting or using Trespass. Flood can also be released during the invulnerable period of Trespass.
	+ If repositioning isn't necessary, it can sometimes be helpful to fire Flood without charging depending on the situation.
* As  heals Void Fiend while it is sprinting, it can be difficult to reach maximum corruption or maintain corrupted form.
* increases base health regeneration, but does not count as healing for the purpose of lowering corruption.
* Repeated use of Suppress can greatly extend how long the Void Fiend can survive outside the safe zones in the   Void Fields and Simulacrum, especially with high attack speed.
* With a high number of void items, it is possible to transform almost on demand by either not using Suppress to become corrupted or by ceasing attacking to become uncorrupted.
* When reaching 100% minimum Corruption by having 50+ void items, using uncorrupted skills becomes impossible. While this is unlikely to happen in the majority of runs, keep it in mind when using the Artifact of Command or on long runs.
* While healing reduces the corruption meter by an equivalent percentage of the full health fraction healed, using the Suppress skill always removes 25% corruption regardless of how much healing is received.
	+ This makes  extremely potent, while playing on Eclipse 5 difficulty negates its effectiveness.
	+ will remove 25% corruption even though no healing is received. It will then remove another 50% slowly as the healing from the item is released. This makes it quite difficult to build up the corruption meter.
	+ Similarly, Corrupted Suppress will always increase the corruption meter whether any damage is received or not.  and  make it possible to extend the corrupted form without sacrificing any health.
* While  can increase the number of Corrupted Suppress charges, picking up a Lysate Cell while in the corrupted form will not grant an extra until reentering its corrupted state.
	+ Conversely, Suppress does instantly detect the change and provides an extra charge. However, an extra charge of Suppress is redundant and not beneficial if corruption is available.
* If Void Fiend has at least 13 void items, it can heal infinitely using Suppress.
* The  can be useful for Void Fiend. Gaining barrier does not reduce corruption like healing, but will still increase corruption when Void Fiend is damaged.
* Because critical strikes increase corruption, items such as , , and  can help increase corruption in early stages.
	+ The  is excellent for maintaining 100% corruption when using Corrupted Drown, greatly increasing damage output and prolonging the corrupted transformation.
* Unsurprisingly, Void Fiend is well-suited to surviving in the   Void Fields. The damage from  increases its corruption, allowing use of Suppress to heal. This makes exploring the Void Fields far less daunting of a task, even with almost no items.
	+ This is useful but not nearly as effective in Simulacrum, where Void Fog damage increases progressively. The player should also be careful about managing the corruption meter as the skill activation delay and accumulated damage can transform Void Fiend into its corrupted form. Being stranded in the Void Fog without healing is usually lethal.

It also emerges instantly upon pressing the interact key, rather than after a brief delay to open the Escape Pod door like most other survivors.
* It is possible that like , the Void Fiend was caught and/or imprisoned by void monsters during its time as a Commando.
	+ Unlike Acrid, who was imprisoned in the Void Fields, Void Fiend's logbook entry suggests it was instead held in the Simulacrum for training.
