The first requirement they have to meet in order to become godlings is to have an innate talent that is compatible with the pathway and has reached 100% in its mastery and usage.
The compatibility of an innate talent and its mastery of 100% are mutually exclusive. One cannot exist without the other. This is why they are counted as one requirement.
Only innate talents that are compatible with one's pathway can reach a mastery of 100%. So angels that are missing a compatible innate talent cannot meet this requirement.
The second requirement is to reach 100% mastery of every divine ability in the pathway. So the average mastery of divine abilities from rank 1 to rank 9 must be 100%.
The third and most important requirement that they have to meet before they can become godlings is to advance the status of the innate talent to the level of a divine ability by imbibing a divine fragment.
