Steal An Egg mutations and income multipliers
Mutations can change the value of a pet, but odds and event mechanics are volatile. Treat this as a planning guide with visible source labels.

Fusion is a source of mutation confusion, not a confirmed multiplier list
Public guides now separate the base Fuse Machine from the Angels vs Demons Secret Shrine. Neither system publishes reliable odds here, and current shrine output claims are still incomplete.

Fractured mutation: how to get it
Rift coverage identifies mutation consumables from the Boss Shop and Boss Mastery. Read the item’s stated success chance before using one on a pet; buying a consumable does not guarantee a successful mutation.
Income multiplier: x2.75 in a community-reviewed v490 client catalog. This is now available as a calculator preset, but it is still not a developer-published stat sheet. Confirm the final number on the live pet card.
Rift boss and token guide →Keep different percentages separate
An item’s success chance is not its income multiplier. Neither establishes the chance of hatching a particular Rift pet.

Sakura Incubator · checked September 19, 2026
Bloom and Spirit Bloom need a separate route
Bloom mutations are reported through the Sakura Incubator, not as a generic hatch-table roll. Plan the route around the Cherry Blossom biome, a Crane unlock prompt, Great Bloom crystals, and an unhatched egg that is worth upgrading.
Read the Sakura Incubator guide →What the guide adds
A newer community client-catalog review reports Bloom at x1.25 and Spirit Bloom at x2.5, superseding the older x1.5 and x3 planning values used on this site. Its chance function rises with charge and paid luck; the live incubator remains the final check before spending crystals.
Multiplier table
Use current client-derived values, then check the live card
| Mutation | Multiplier | Source posture | Guide |
|---|---|---|---|
| None | x1 | Player input baseline | Use the visible pet income as your base value. |
| Silver | x1.2 | Community client catalog v490 | Client-derived planning value checked September 19; confirm the live pet card. |
| Bloom | x1.25 | Community client catalog v490 | Configured as Sakura. Availability and event rules can change independently of income. |
| Golden | x2.5 | Community client catalog v490 | Client-derived planning value, not a developer-published stat sheet. |
| Rainbow | x3.5 | Community client catalog v490 | Use the live card when boosts or multiple mutations are active. |
| Spirit Bloom | x2.5 | Community client catalog v490 | Configured as GreatBloom. Older public guides report different multipliers. |
| Parasite | x3 | Community client catalog v490 | Configured as Monstrous. Acquisition and current availability require a live check. |
| Fractured | x2.75 | Community client catalog v490 | Configured as Boss. Keep item success chance separate from income multiplier. |
Stacking rule
Multiple mutations add their bonuses above x1
The reviewed client function adds each mutation's bonus above the normal x1 base. It does not multiply every full scalar together. Golden plus Rainbow is therefore modeled as x5, not x8.75.
Planning note
Mutation value depends on the pet underneath
A strong multiplier on a weak pet can still lose to a better base pet. Use the calculator with the income you see in game.
