Jinn

Steel Soul Jinn is an NPC exclusive to Steel Soul Mode, replacing Confessor Jiji in the cave at the east end of Dirtmouth, due to permanent death making Confessor Jiji's service useless.

She is located inside the cave in Dirtmouth and buys Rancid Eggs for each.

Steel Soul Jinn states that she is too young to tell much about herself, although she does say that her body is unable to take damage. She mentions her friend who appreciates the Rancid Eggs that The Knight can trade with her; this friend is most likely Confessor Jiji.
