Supreme hatchling

Supreme hatchling is a miniature version of Dagannoth Supreme that can be unlocked as a pet from a dagannoth scale, which is obtained as a drop from killing Dagannoth Supreme. The chances of obtaining the item are 1 in 2,500 with a threshold of 1500 (explanation of drop mechanics). After the item is used, the supreme hatchling can be summoned from the pets tab in the hero interface.
