Void Fiend

The  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.

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 very quickly 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 a or two makes the ability spammable, which can easily launch Void Fiend massive distances.
 * Make sure to use up all charges of Flood to extend corruption as transforming will reset the cooldown.
 * By firing multiple charges of Corrupted Flood at the ground, Void Fiend can stall in the air for a limited amount of time.
 * 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, it may become difficult to manage Corruption.
 * At default attack speed Void Fiend accumulates an extra 3% corruption within the 1 second it takes for the skill to execute, so it is advised to not activate it above 95% if the player wants to avoid getting 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 for which replaces its healing abilities.
 * The charge time of Flood is substantial, and Void Fiend can't fire Drown while charging. It can however, sprint or use Trespass while charging it, making it helpful to begin charging Flood while repositioning so that it can fire after leaving 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, as the benefits of a quick release outweigh maxing out a charged Flood.
 * 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 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 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 trivializes it.
 * 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 extremely hard to build up the corruption meter.
 * Similarly, Corrupted Suppress will always increase the corruption meter whether any damage is received or not. and especially  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 . 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.

Trivia

 * The Void Fiend is a corrupted, although it is not the Commando who escaped Petrichor V during the events of Risk of Rain 1.
 * Its Umbra title is stylized in-game as 『Co??rupted Am?nesiac】.
 * Its endings are stylized in-game as "『..and s?o it c??omes】... 「fo?r al?l of us.』" and "『..a?nd so it v?ani??shed』, 「a wh?isper in the d??arkness』" respectively.
 * Unlike the other Survivors, the Void Fiend's 'Escaped' ending phrase doesn't use the regular "..and so [he/she/they/it] left" phrase.
 * The Void Fiend is referred to internally as "VOIDSURVIVOR".
 * Since the Void Fiend has two sets of moves that it alternates between based on Corruption, it is the only Survivor who has no alternate loadout skills.
 * Instead of starting in an Escape Pod like most other survivors, the Void Fiend drops in a spherical pod, similar in shape to that of a lunar pod, that launches it slightly upwards upon emerging. 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.
