Mutations give a ridden pet a speed multiplier. There are five listed tiers, beginning with Shocked at x2 Speed and ending with Eternal at x100 Speed.
To get one, place the pet you want to improve on the Mutation Ranch during a mutation storm. The outcome is random, and one pet cannot hold several mutations at once.
Mutation tier list
Ride a Pet mutation tiers
| Mutation | Speed multiplier |
|---|---|
| Shocked | x2 |
| Volted | x3 |
| Rage | x4 |
| Void | x10 |
| Eternal | x100 |
Void is the first large jump in the list, moving from Rage's x4 to x10. Eternal then jumps to x100, making it the strongest listed mutation for movement speed.
The page introduction mentions speed and money multipliers, but the individual mutation rows only provide speed values. There is not enough information to calculate a money bonus from this table.
Getting a mutation
The Mutation Ranch is in the Overworld. When a mutation storm begins:
- Put the target pet on the Ranch.
- Leave it there while the storm is active.
- Check the pet after the mutation event.
- Keep using later storms if you want to move up the tier list.
The available information does not give storm schedules or mutation odds. A storm is an opportunity, not a guaranteed result.
How upgrades work
Each pet has one mutation slot. If a higher-tier mutation hits a pet that already has a lower tier, the stronger mutation replaces it automatically. A weaker result cannot downgrade a stronger mutation.
For example, Volted can replace Shocked, but Shocked cannot replace Volted. The multipliers do not add together, so Shocked and Volted cannot combine into x5 Speed.
This protection means you can leave a mutated pet on the Ranch while chasing a better tier without risking a downgrade.
What is still unclear
The readable source does not identify the exact storm for each mutation, list the chance of each outcome, or provide a storm timer. It also does not quantify effects on jump, weight, or income. Use the table for confirmed speed comparisons and check the live event UI for storm-specific details.
