Each species has a set of traits that all individuals of said species share with one another:
In Delving, all individuals of a species share the same regular attacks, as well as elemental weaknesses and resistances.
Groupings are assigned to a species according to its physical attributes and qualities. It is relatively rare for a species to have three groupings; most have one or two.
Groupings: Reptilian, Mammalian, Avian, Arthropod, Flora, Mechanical, Elemental, Aquatic, Celestial
Seasonal creatures are only available as Wild Caught for their yearly breeding season duration. They will also breed better during this time. When out-of-season, they will only breed true very rarely.
Each individual creature has a set of traits that are not bound by its species. Different traits are visible during each stage, with all traits being visible at the adult stage. Some traits are hidden for growing creatures when they do not have an owner.
Juvenile and adult:
Species info can be found in FRIC. You can find general information such as rarity and variants, as well as detailed statistics. You can view global statistics as well as your own statistics per species.
FRIC will only have entries for already documented species. When a new species is discovered, it will appear in FRIC once its global population has reached a high enough number for Headquarters to create a detailed entry. If you wish to help the effort to document a new species, you are encouraged to collect and raise a few to help add to the pool of recorded individuals. New species cannot be filtered by their species name in searches until they have a FRIC entry.
You can breed your adult creatures together to produce captive bred offspring that keep a viewable record of their ancestry via ancestry trees. Breeding two creatures together does not guarantee that they will produce, and the higher their rarity the less likely they are to breed true.
Two creatures must meet the following criteria in order to be bred together:
While not required for compatibility, the following will give a small boost to a breeding pair that increases the likelihood of them producing:
Regardless of whether or not they produce, after two creatures breed together they will not be able to do so again for 5 days. If you breed creatures while having no space for baby creatures, any resulting offspring will utilise your held creatures space. You cannot breed creatures if you have no space for held creatures. The result screen for breeding contains a link to the abandon prompt for successes, should you not want to keep the new offspring.
All captive bred creatures can be traced all the way back to their wild caught ancestors via ancestry trees. The tree of a wild caught creature can be viewed, but it will only display said creature by itself. The ID box colour for wild caught and captive bred creatures are different for quick origin identification within the tree. The maximum amount of generations displayed in an ancestry tree is 8 (not including the creature whose tree is being viewed).
You can view the tree of any creature displayed within a tree by clicking their thumbnail. Similarly, you can click their ID to go to their info page.
