No changes since we started tracking on Sep 28, 2026. When Steal An Egg buffs or nerfs World Burner, it shows up here.
World Burner is the Dark side counterpart to 
ArchAngel, the single Divine pet inside the Demon Egg in the Angels & Demons biome. It was added in the same update and matches ArchAngel almost exactly on income.
Its Demon Egg takes about 15 hours to hatch, one of the longer waits in the game, and the game's own Pet Index pays out a large one-time bonus for indexing it: $500 billion in cash plus 600 million Speed. That reward alone makes hatching your first one worth the wait even before you count its ongoing income.
The catch is the same as its Light counterpart: Angels & Demons needs 20 billion Speed to enter safely, and the Demon Egg only appears during the Demons night phase, so you cannot rush it.
