Bone Emperor guide
Bone Emperor is a Divine earning $7.5B/s. It ranks 8th of 20 Divines, just above the $6.9B/s median, and 2nd of 29 in the Halloween Dimension, after only Voidseer Pumpkin. Mecha Scrambler, an Event pet, earns the same amount, and Aetheron from Angels & Demons sits just below at $6.9B/s.
It comes from the shared Halloween Egg, listed with a grow time of about 10 seconds and a $750B hatch reward. That is the same egg that gives Pumpkin Fiend at $35K/s, so a single pull can land anywhere on a scale of 200,000 to one.
The Bone Emperor also has a Zombified Bone Emperor, a Divine at $14B/s, 1.87 times the base figure. It is the smallest jump of any Zombified pair, which tells you the plain pet is already near the ceiling of its group. Its own mutations reach about $9B/s with Silver, $18.75B/s with Golden and $26.25B/s with Rainbow, and a Golden one would already beat the plain Spirit World Guardian at $15B/s.
