Familiar

From The Binding of Isaac: Rebirth Wiki
(Redirected from Category:Familiars)
Jump to navigation Jump to search

Familiars are small companions, usually generated by passive items, that follow and assist Isaac. Effects of familiars include (but are not limited to) pickup generation, shooting familiars that fire their own tears at enemies, and orbitals that act as projectile shields and/or deal contact damage.

Many of these familiars (especially pickup generation and shooting familiars) follow behind Isaac. When Isaac picks up multiple of these following familiars, they form a line behind him from oldest to newest (with closest familiar behind Isaac being the oldest one picked up) rather than constantly overlapping one another on the same spot behind Isaac.

  • (in Repentance and Repentance+) In addition to being chronologically ordered, certain familiars on the line take priority over others in how close their position is to Isaac.

Isaac cannot have more than 64 total familiars at once. This includes blue spiders and flies, familiar items such as Collectible Dry Baby icon.pngDry Baby, (in Repentance and Repentance+) Character Tainted Eve icon.pngTainted Eve's blood clots, etc. Gaining more than this will result in familiars being destroyed, with blue spiders and flies being destroyed first.

Temporary Familiars

Blue Flies

Blue Fly.png
