Keeper's Kin is an unlockable passive item added in The Binding of Isaac: Repentance.

Effects

• If Isaac is in a room with enemies, rocks and rock-like obstacles will occasionally spawn blue spiders.
• Causes all rocks to spawn 0-2 blue spiders when destroyed.
• This item belongs to the Spider Baby set. Collecting three items from this set will transform Isaac into a humanoid spider.

Synergies

• D12: Due to the high tendency of replacing rocks with TNT, it allows for easy destruction of nearby rocks, resulting in lots of blue spiders.
• Leo / Thunder Thighs: As Isaac can break all reachable rocks, he can amass a lot of blue spiders.
