Other Divine pets
World Burner guide
The Darkness list from Update 4 climbs from Flame Sprite at $225/s all the way to World Burner at $5B/s, and World Burner closes it. It is the Divine of the Demon side of Angels & Demons and, at the same time, one of the biome's three guardians alongside ArchAngel and Aetheron.
Demon nights only
Angels & Demons transforms every night into either an Angel or a Demon version, each with its own 8 pets. World Burner's nest belongs to the Demon set, so on an Angel night you won't find it; the rare Merged form, which combines both sides with extra luck, is the other chance. Getting in requires 20B Speed, the highest requirement of the twelve biomes, and the whole run happens with the biome's guardians on your tail.
The wiki has not published a grow time or a hatch reward for the World Burner Egg, so plan around the income alone.
What the pet earns
- $5B/s base: 2nd of 18 in the biome, tied with ArchAngel and below Aetheron ($6.9B/s).
- 5th of 14 Divine pets (tied with ArchAngel and Sabertooth); just 4 pets in the game earn more.
- On a Demon night it is the best pet on offer by a wide margin: the next Darkness pet down, Skeleton Horse, makes $1.3B/s.
Estimates from the formula the wiki documents:
- Golden: about $12.5B/s
- Rainbow: about $17.5B/s
- 10x its 120,000 kg base weight: about $20.7B/s
- 200x base weight: about $118B/s
The biome's Secret Shrine fuses a Light pet with its Darkness counterpart of the same rarity, and the wiki's recipe for the Divine pair is World Burner plus ArchAngel, which crafts Aetheron. If the night turns Demon and you already own ArchAngel, this is the egg to go for.
