Acrid

 is a playable character in Risk of Rain 2.

A macabre, poison-spewing ex-prisoner, Acrid fights with a potent array of damage-over-time effects and self-sustaining melee ability, as well as a mix of long-range and crowd control options for any situation. It also sports the highest base damage stat of any Survivor barring the, allowing for even greater damage potential.

Acrid's unique ability to inflict or  status effects makes it an incredibly lethal choice when stacking items that inflict additional debuffs.

Tips

 * Choosing between Poison and Blight is largely a personal preference.
 * Since Poison cannot stack, it favors a dodgier, fire-and-forget playstyle where the player poisons a group of enemies, leaves them to take damage, and finds some new enemies to poison in the meantime.
 * On the other hand, Blight favors an aggressive playstyle and rewards using more skills, as each skill effectively deals 320% more base damage.
 * The damage from both Poison and Blight can be increased with, , , , , and.
 * Blight is also affected by the and, since it uses Acrid's base damage.
 * It is surprisingly simple to determine when Poison is dealing the least possible damage by observing the damage dealt by each tick. If the damage per tick is Acrid's level plus 4, then the victim's maximum HP is so low that Poison is only dealing the minimum damage possible to it.
 * This observation can be muddled by the aforementioned damage-boosting items, however.
 * Since the buff from Vicious Wounds and Ravenous Bite is considered health regeneration, it will be massively amplified by . However, this also means that it won't interact with items like,  or.
 * Despite being regeneration, it is not affected by the regeneration modifiers from or, and is not removed when.
 * Getting a reduces the cooldown of Neurotoxin and Ravenous Bite to the minimum of 0.5 seconds. This enables Acrid to rapidly fire off ranged attacks, or to repeatedly bite enemies and regenerate massive amounts of health.
 * Vicious Wounds' attack animation can be cancelled and reset by initiating a sprint. This allows Acrid to attack extremely quickly with no items. In Development Thoughts #11 it was noted this behavior will likely get removed.
 * Acrid takes no fall damage while using Caustic Leap or Frenzied Leap.
 * The player can use Caustic Leap or Frenzied Leap after falling off the map to avoid taking fall damage.
 * Epidemic gives Acrid great early-game area-of-effect damage. When combined with items such as the, , and , this lets Acrid easily clear crowds of enemies.
 * Intentionally shooting Epidemic at the floor or walls can reliably hit flying monsters such as.
 * Acrid does not spawn from an Escape Pod, making Acrid unable to unlock Power Plant in a single-player run.

Trivia

 * The challenge necessary to unlock Acrid, "...To be left alone" is a reference to Acrid's victory screen from the first Risk of Rain, which reads "...And so it left, with a new hunger: to be left alone."
 * Acrid is referred to internally as "Croco," and the Regenerative buff is referred to as "CrocoRegen."
 * Acrid is commonly known as “Poison Doggo” as an internet meme.
 * Instead of starting in an Escape Pod, Acrid starts asleep on the surface of the planet. During its wake up animation, it is actually vulnerable to enemy attack before the player is given control if its spawn location is particularly unlucky.
 * Acrid originally fell onto Petrichor V, along with the majority of the UES Contact Light's cargo, locked inside of a crate that landed atop the area known as Sunken Tomb. It can be presumed that the managed to imprison it in the  between the events of Risk of Rain 1 and 2.
 * Although Acrid somewhat resembles a, it has been confirmed by developer Hopoo that it is not a Lemurian.
 * Epidemic's enemy limit is completely unfeasible to reach under normal gameplay circumstances; since it spreads to 2 enemies at a time, up to 20 times, it can affect a total of 1 + 2^20 = 1048577 enemies. For comparison, the maximum number of monsters that can exist at once is 40.
