On the "Soulbound Doll" NPC, it has info under the "Tactics" and "Source" sections that is for another NPC. It should read:
During Combat: Once the dolls realize they have larger
playmates, they clamber up onto the disk to become
invisible if the PCs aren’t yet in the courtyard. Otherwise,
they grow silent and stalk stealthily toward the sounds of the
PCs. The dolls are competitive when they fight, shrieking
and giggling and never attacking the same foe unless there
are no other targets, yet once a doll takes damage, the
others quickly come to its aid and focus all their attacks on
the same foe.
