Koluk eggs are a common sight in almost every treasure hoard. In particular, Solire and Dragold hoards will have dozens of Koluk eggs. This is both because of their shiny exteriors and their ability to influence luck in regards to finding objects. Koluk eggs will even attract small amounts of objects, some quite rare indeed.
Koluks are one of several Ark species that loves to hoard objects. These hoards can contain anything and everything, even things that would normally be too large for the Koluk to move on its own. This is because other hoarding creatures will gladly share their hoards with a Koluk or two or more. The luck that emanated from a Koluk's egg is amplified once the Koluk hatches, however this luck is not a passive ability any more and must be willingly shared to gain its effects. Thus many larger creatures will dedicate small parts of their hoard for friendly Koluks and reap the benefits of lucky rare finds for their main hoards.
