Binding of Isaac: Rebirth Wiki

Spiders are arachnid enemies that can be commonly found in most chapters. They move quickly and will go in all directions randomly, making them unpredictable. However, if they have a direct line of sight on Isaac, and are close enough, they will move towards him. They are also able to fit through small diagonal gaps.

Variations[]

Big Spider[]

Big Spiders look like regular Spiders, but with a large black abdomen attached. They behave in the same way as the regular Spiders, having the same movement speed and erratic behavior. However, they have over triple the health of regular Spiders, and upon death, they will split into two regular Spiders. They will not split if they are killed by an explosion.

Swarm Spider[]

Added in Repentance

Swarm Spiders act much like normal Spiders but are much smaller and tend to come in much larger groups. They also hop and flash a bright yellow.

They are spawned by Eggies in large number when one dies.

Strider[]

Added in Repentance

Striders are a type of spider that can only spawn in Downpour Downpour and special rooms in Dross Dross. They glide on the water towards Isaac in short bursts and can swim across flooded gaps.
