Prime hatchling is a miniature version of Dagannoth Prime that can be unlocked as a pet from a Dagannoth egg, which is obtained as a drop from killing Dagannoth Prime. The chances of obtaining the item increases with the number of kills recorded in the beasts tab (explanation of drop mechanics). After the item is used, Prime hatchling can be summoned from the pets tab in the hero interface.
