脐带#33

Umbilical Cord is a trinket.

• When Isaac's health is brought down to half a red heart and no soul hearts, a Little Steven familiar spawns for the current room.
• When Isaac enters a room and has half a red heart or less, a Little Steven familiar spawns and will remain until red health is restored to above a Half Red Heart, disappearing after entering another room.
• Characters which cannot acquire red heart containers in any way will always have a Little Steven.
• When Isaac takes damage, there is a high chance to spawn a Gemini familiar for the current room. This effect is stackable.

• An umbilical cord is a tube that is connected to a fetus via the placenta and is used to give nutrients, blood, and oxygen to the growing child. The Binding of Isaac: Rebirth
