Other Divine pets
Aetheron guide
Only two pets in Steal an Egg earn more than Aetheron. At $6.9B/s it tops every other entry in Angels & Demons, clearing the two other Divine guardians, ArchAngel and World Burner, by $1.9B per second.
Guardian, and a Shrine fusion
Aetheron is one of the three guardians of Angels & Demons, the twelfth biome, which needs 20B Speed before you can realistically outrun them. Unlike ArchAngel and World Burner, it isn't on either of Update 4's lists of 8 Light and 8 Darkness animals, because it is the fusion of those two. The biome's Secret Shrine combines a Light pet with its Darkness counterpart of the same rarity, and the wiki's recipe for Aetheron is ArchAngel (the Light Divine) plus World Burner (the Darkness Divine). No extra cost or success chance is listed for the fusion.
An 18-hour egg
The Aetheron Egg needs 18 hours to grow, the longest timer recorded in this biome (Equinox takes 10hrs, Pegasus and Skeleton Horse 5h). The wiki doesn't list a hatch reward. The X2 Growth Speed gamepass (467 Robux) makes eggs grow twice as fast, which would bring that wait down to about 9 hours.
Income with mutations and weight
Its listed base weight is 12,000 kg, a tenth of the 120,000 kg given for ArchAngel and World Burner. Because the wiki's formula works from the ratio between actual and base weight, the same multiples apply. Estimated with that formula:
- Golden: about $17.2B/s
- Rainbow: about $24.1B/s
- 10x base weight: about $28.5B/s
- 100x base weight: about $118B/s
- Rainbow plus 100x weight: around $413B/s
It ranks 3rd of 14 Divine pets, so even the top biome's best pet sits just below the very ceiling of the game.
