Other Eternal pets
Skeleton Horse guide
Skeleton Horse is the Eternal of the Darkness side of Angels & Demons. Update 4 placed it in the Demon line-up beside Flame Sprite, Toro, Imp, Demon Hound, Gargoyle, RazorFang and World Burner, so its nest belongs to nights when the biome takes its Demon theme. The rare Merged form, which mixes both sides with extra luck, is the other window.
Getting in and getting out
Angels & Demons is the twelfth biome and needs 20B Speed. Its guardians are the zone's three Divine pets: ArchAngel, World Burner and Aetheron. The Skeleton Horse Egg then grows for 5h, so a run here is a real commitment: you dodge the strongest guardians in the game and then wait five hours for the hatch.
The hatch pays +200M Speed and $130B. Its Light mirror, Pegasus, earns the same $1.3B/s, grows in the same 5h and gives the same Speed, but pays $140B. When both are available Pegasus wins on cash by $10B; on a Demon night, Skeleton Horse is the highest earner on the Darkness list below World Burner itself.
Numbers worth knowing
- Base income: $1.3B/s, tied with Pegasus for 5th of 18 in the biome and for 9th of 24 Eternal pets.
- Golden (x2.5): about $3.25B/s. Rainbow (x3.5): about $4.55B/s.
- Weight at 10x / 100x / 200x of its 65,000 kg base: roughly $5.38B, $22.2B and $30.8B per second.
All of these are estimates from the formula the wiki documents, not guaranteed values.
The biome hides a Secret Shrine that combines a Light pet with its Darkness counterpart of the same rarity, and the wiki confirms the recipe for this pair: Skeleton Horse plus Pegasus crafts Equinox ($1.8B/s). If you already own a Pegasus, hatching one of these completes it.
