Abyss Overlord guide
Abyss Overlord holds an odd record: of the 35 Secret pets in the game, it earns the least, at $1.25M/s. Several Cosmic pets, a lower rarity, earn more, including Bronto ($1.5M/s), La Vacca Saturno Saturnita ($2.2M/s) and Dreadclaw from the Rift itself ($2.2M/s).
A name shared with the boss
The Overlord is the boss you fight inside the timed Rifts that open every 30 minutes. The wiki's Rift page groups its pets from every banner and boss reward into one list, but it does not say whether Abyss Overlord is a banner pet or a boss reward. The name suggests a link to the boss, yet the wiki leaves that unconfirmed, so treat any claim that it drops from the Overlord as unverified.
What the wiki does describe:
- Defeating the Overlord earns Boss Tokens and Boss Mastery Points.
- The Mastery track rewards increasingly valuable items, including eggs pre-loaded with the Fractured mutation.
- The permanent lobby Rift trades 3 random pets for one exclusive Rift Egg, under banners that rotate every 3 hours. Update 6 notes that the Rift Trade-In Machine was replaced by Dr. Scramble's Laboratory.
Mutations matter more than rarity here
Since its base sits at the floor of the Secret tier, a mutation changes its standing quickly. With the wiki's formula and the listed 13,000 kg base weight:
- Golden: about $3.12M/s
- Fractured (×2.75): about $3.44M/s
- Rainbow: about $4.38M/s
- 10× weight: about $5.17M/s
- 100× weight: about $21.4M/s
- Rainbow at 100× weight: about $74.9M/s
It is the 10th of 16 Rift pets by income.
