Spider Mod is a passive item added in the Binding of Isaac: Afterbirth expansion.
Contents
Effects[]
- Spawns a grey spider familiar that wanders around and allows Isaac to see tear damage and the health bars of all enemies.
- The spider will inflict a random status effect on any enemies it comes into contact with.
- The spider will sometimes drop a
Lil' Battery or spawn a Blue Spider when a room is completed.
This item belongs to the Spider Baby set. Collecting three items from this set will transform Isaac into a humanoid spider.
Notes[]
For the sake of simplicity, all damage values shown are multiplied by 10 and rounded up to the nearest number.
Damage values are no longer multiplied or rounded.
- All stats effect damage dealt by Spider Mod is based on Isaac's damage stat.
- Spider Mod reveals
Mega Satan's health bar and is the only way to see his health.
In Repentance, doesn't reveal
Mega Satan's life bar during his second phase anymore.
Spider Mod also reveals the health bar for
Mother, the Ultra Harbingers, and
The Beast.
- Spider Mod shows the health of invincible enemies, holes created by
Little Horn, and the golden statue of
Ultra Greed.
- Spider Mod doesn't show if a segmented enemy has individual segment health like
Larry Jr. or a health pool like
Chub. Against enemies with invulnerable segments such as
Carrion Queen and
Scolex, its indicators will not differentiate between damage dealt to invulnerable and vulnerable segments.
- Spider Mod's damage doesn't account for enemy damage reduction or invulnerability, which means that the damage indicators for
Mushrooms,
Stone Grimaces, and similar enemies will be inaccurate.
If Isaac transforms into
Spider Baby, it spawns a spider familiar who works similarly to Spider Mod.
Synergies[]
BFFS!: Makes Spider Mod bigger and increases the chance for Spider Mod to spawn a battery or blue spider. No effect on stat effect damage.
Hive Mind: Makes Spider Mod bigger. Whether or not this impacts spawn chances or damage is unknown.

Trivia[]
- This item is a reference to Spidermod, a modification to the original Binding of Isaac, which was made by one of the lead Rebirth developers, Spider853. One feature of Spidermod was to show damage numbers onscreen.
