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 symbol/effect associated with them for easy identification. These colorations are not to be confused with champions.
Afflicted enemies take 4 to 6 fire damage over time, like poison. Afflicted enemies will be tinted orange for the duration and have a fire symbol above them. Afflicted enemies will sustain double Isaac's tear damage over time.
Afflicted enemies will temporarily fight on Isaac's side, running toward other enemies and damaging them for 25% of their maximum HP per touch, 5 damage with half heart projectiles and 10 with full heart ones. 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. Charmed enemies will prioritize non-charmed enemies and won't target invincible enemies. Charmed Portals will also spawn friendly enemies.
Afflicted enemies are slowed and walk around randomly. While confused, most non-boss enemies will be unable to attack. Afflicted enemies will be tinted pale gray and have stars above them.
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. Afflicted enemies will be tinted purple and have a skull symbol above them.
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 Midas' Touch, in which case they will be shaded gold).
Afflicted enemies sustain 4 to 6 damage over time. Afflicted enemies will be tinted green and have a bubbly effect surrounding them. Afflicted enemies will sustain double Isaac's tear damage over time.
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, decreasing their range as well. 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. Slowed projectiles no longer have their range affected, and attacks that rely on momentum no longer end prematurely.
Afflicted enemies are permanently charmed and will fight on Isaac's side until they die. Most enemies under this effect will follow Isaac across rooms, like a familiar. 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 still have heart effects.
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 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 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.
Afflicted enemies will be attacked by other enemies, functioning like a reverse charm effect. Afflicted enemies are tinted red.

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.
