There's a glitch about half way through the baby stage where the baby attacks you regardless of the gland buff this drains it's stamina which will drain it's food to recharge as long as your baby has food in it's inventory it wont starve because of this even if it's food hits zero just feed it like normal and keep a close eye on it
Since i cant find this anywhere. Reapers take reduced damage naturally so its a good soaker. Dont bring light pets near theese because they take more damage and deal less damage.The reaper burns when light is near it. Nameless will attack it tho. Sorry for bad english.
