Status Effects

From The Binding of Isaac: Rebirth Wiki
Jump to navigation Jump to search
This article is about effects which can be inflicted on monsters. For the different kinds of effects which Isaac's primary weapon can have, see Tear Effects.

Status effects are special effects that can be inflicted on an enemy from a variety of sources, such as tears, bombs, and items. Each status effect has a color and/or symbol/effect associated with them for easy identification. These colorations are not to be confused with champions.

Effects

Effect Appearance Description
Burn Burn Effect.png (in Rebirth)Afflicted enemies take 4 to 6 fire damage over time. Afflicted enemies will be tinted orange for the duration and have a fire symbol above them.
(except in Rebirth)Afflicted enemies will sustain double Isaac's tear damage over time. Afflicted enemies will be tinted orange for the duration and have a fire symbol above them.
Charm Charm Effect.png Afflicted enemies will temporarily fight on Isaac's side, running toward and/or shooting at other enemies and damaging them for 25% of their maximum HP per touch, 5 damage with half-heart-dealing projectiles, and 10 with full-heart-dealing projectiles. If no other enemies are in the room, a charmed enemy will instead run towards Isaac. (Charmed enemies can still hurt Isaac.) Afflicted enemies will be tinted pink for the duration and have a heart symbol above them. Most enemies with ranged attacks will not fire them (but can damage other enemies with them if they do — see the above "monster infighting" damage description).
(except in Rebirth and Afterbirth)Charmed enemies will prioritize non-charmed enemies and won't target invincible enemies. Charmed Portals will also spawn friendly enemies.
Confusion/Concussion[Details 1] Confusion Effect.png Afflicted enemies are slowed and walk around randomly. While confused, most non-boss enemies will be unable to attack. Bosses will have randomized movement, but will still be able to fire projectiles at Isaac. Afflicted enemies will be tinted pale gray and have stars above them.
Fear Fear Effect.png Afflicted enemies are scared of Isaac and will run away from him. While scared, most non-boss enemies will be unable to attack or charge towards Isaac. Bosses will run away from Isaac, but will still be able to shoot projectiles at him. Afflicted enemies will be tinted purple and have a skull symbol above them.
Petrified Petrified Effect.png Afflicted enemies are stopped in place. They cannot move or attack. Afflicted enemies will be shaded brown-gray as if turned to stone (unless petrified by Collectible Midas' Touch icon.pngMidas' Touch, in which case they will be shaded gold).[Details 2]
Poison Poison Effect.png (in Rebirth)Afflicted enemies sustain 4 to 6 damage over time. Afflicted enemies will be tinted green and have a bubbly effect surrounding them.
(except in Rebirth)Afflicted enemies will sustain double Isaac's tear damage over time. Afflicted enemies will be tinted green and have a bubbly effect surrounding them.
Slow Slow Effect.png Afflicted enemies are slowed down to approximately 51.3% of their original speed. Any projectiles they shoot will also be slowed down to the same amount. Attacks that end when the enemy runs out of momentum, such as the charging attacks of Gurdy Jr. and Dingle, will be vastly shortened in duration. Depending on the item that triggers the slow effect, afflicted enemies will be tinted black or white with a snail icon above them.
(except in Repentance and Repentance+)Slowed projectiles will lose momentum much more quickly, greatly reducing their total range.
(except in Rebirth)
Friendly
Friendly Effect.png Afflicted enemies are permanently charmed[Details 3] and will fight on Isaac's side until they die.[Details 4] Most enemies under this effect will follow Isaac across rooms, like a familiar.[Details 5] Friendly enemies cannot hurt Isaac, but many of them will still chase and "attack" Isaac in a room with no enemies. Friendly enemies are not tinted, but have heart symbols above their head.
(except in Rebirth)
Shrink
Gaper.png Afflicted enemies are shrunken and will run away from Isaac. Isaac can walk over shrunken enemies to kill them.
(except in Rebirth and Afterbirth)
Bleed
Bleed Effect.png (except in Repentance and Repentance+)Afflicted enemies take damage equal to 10% of their maximum health every 5 seconds.
(in Repentance and Repentance+)Afflicted enemies take damage based on how quickly they move; the faster the enemy, the more damage they take. While moving, a bleeding enemy leaves behind red creep that can damage other enemies.
(in Repentance and Repentance+)
Bait
Mark Effect.png Afflicted enemies will be attacked by other enemies, functioning like a reverse charm effect. Afflicted enemies are tinted red.
(in Repentance and Repentance+)
Chained
Chained Effect.png Afflicted enemies are chained in place, preventing them from taking any action.
(in Repentance and Repentance+)
Frozen
Frozen Effect.png Enemies that are killed by items that can inflict Frozen become ice statues on death that block both Isaac's tears and enemy shots. Ice statues can also be pushed by Isaac, causing them to slide, leaving damaging blue creep (which deals 22 damage per second), until they hit an obstacle or enemy, dealing 35 damage to enemies they collide with. After an ice statue blocks 10 shots or collides with something while sliding, it shatters into a ring of 10 icicles which slow and deal 8 + (floor − 1) damage to enemies they hit. Enemies that are killed by these icicles also become ice statues. Frozen enemies will not trigger any of their on-death effects, such as exploding or splitting, making this effect useful for enemies with multiple forms.

Notes

  1. "Confusion" is the proper name of this status effect, but it is sometimes referred to as "Concussion" in certain item and effect descriptions (such as Collectible Iron Bar icon.pngIron Bar).
  2. Enemies that are petrified by Midas' Touch or an analogous effect (e.g. (except in Rebirth and Afterbirth)Collectible Eye of Greed icon.pngEye of Greed and Gold Heart) will drop coins on death. This does not happen with other petrification effects, even if Isaac is able to inflict both kinds in the same build, which is why Midas' Touch applies different shading. (in Repentance+) if a violet champion monster is killed while it is gold-petrified, the trinket it drops is guaranteed to be a golden one. Rainbow champions still drop normal trinkets.
  3. While most friendly enemies are spawned with the condition, it is possible for a non-friendly enemy to become friendly without being killed. In this scenario, the enemy in question will still be treated as though it was dead for purposes such as whether or not a room counts as cleared.
  4. Friendly enemies can take damage, including contact and projectile damage, from non-friendly enemies (blocking most enemy projectiles in the process), which works like how charmed enemies deal damage to other enemies. (Friendly and non-friendly enemies making contact with each other generally damage each other more-or-less at the same time if both enemies can cause contact damage.) Some charmed or friendly enemies can also take damage in different ways (such as (in Repentance and Repentance+) Bishop.pngBishops taking damage when they prevent damage being dealt to Isaac).
  5. Some friendly-inducing effects cause affected enemies to despawn when Isaac leaves the room.
  • Host-type enemies will take burn and poison damage even if their skull is down, and all status effects can be applied by tears even if their skulls are down.
    • If a Host-type enemy is petrified, they will take damage regardless of if they are vulnerable or not.
  • After a boss or mini-boss has had a status effect applied on them, they will receive immunity against all status effects for 8 seconds. This means that no other status effect can be applied to that enemy during this period.
    • The slow effect is an exception to this rule.
