Other Secret pets
RazorFang guide
+90M Speed from a single egg: no other Secret from Abyss Ocean through Angels & Demons has a documented hatch reward that large, and only the zone's Eternals Pegasus and Skeleton Horse (+200M each) go higher. RazorFang pairs that with $350M/s of income, the top of the Secret tier in its zone.
RazorFang Egg
- Biome: Angels & Demons, 12th in the biome order
- Speed requirement: 20B
- Zone guardians: ArchAngel, World Burner and Aetheron
- Grow time: 3h 15m
- Hatch reward: +90M Speed and $35B
- Base weight: 12,000 kg
Why the reward stands out
The Secret just below it, the Gargoyle, pays +30m Speed after 3 hours; RazorFang pays three times that for an extra 15 minutes, along with $35B instead of $22.5b and about 56% more income. Next to the previous zone's Secret, the Mutant Shark (+4.1m Speed, 3 hours), the gap is even wider, more than twenty times the Speed.
The $35B is enough for the Galaxy Trail (20B, 5×) with plenty left over.
Twin and position
RazorFang's income and base weight match the Centaur, but the wiki has documented a reward and grow time only for RazorFang.
- 7th of 18 in Angels & Demons, tied with the Centaur
- Tied for 11th of 35 Secret pets
- 48 of 198 pets earn more overall
Estimates with mutations and size
Using the formula the wiki documents (its calculator is still labelled beta):
- Golden: about $875M/s
- Rainbow: about $1.23B/s
- 10× base weight: about $1.45B/s
- 100× base weight: about $5.99B/s
- 200× base weight: about $8.29B/s
- Rainbow with 100× weight: about $21B/s
Angels & Demons pets are not part of the Rift Sacrifice tiers, and the Laboratory's Unstable DNA list for this zone stops at the Gargoyle and Pure Jellyfish, so RazorFang is not used in either trade.
