Values are the exact figures the game applies, not the rounded ones most guides quote.
Roll weight is the game’s own lottery weighting — higher means it appears more often when a random trait is rolled. It is a relative weight, not a percentage, and the game files contain no table converting it to one.
How to get Eternal Engine in Palworld
- Pal Surgery Table. Apply Disposable Implant: Eternal Engine at the Pal Surgery Table. The disposable implant is used up by the operation. To get the implant, it comes out of the ancient relic recycler (0.05% per item).
- No Pal is born with it, so it never comes guaranteed on a catch.
- Breed it down. A parent carrying Eternal Engine can pass it to the egg — how passive inheritance works.
- Random roll. It can roll on any caught or bred Pal, with a roll weight of 5 — one of the rarer weights.
Pals born with Eternal Engine
No Pal is born with Eternal Engine — it appears as a rolled trait, or is inherited from a parent that already carries it. Palworld’s files contain no inheritance probability table, so anyone quoting you odds for that is estimating.
Other passives that change Partner skill charge
Eternal Engine gives +75%. Nothing in the game beats that, so this is the one to keep. A higher number is better here.
| Passive | Partner skill charge | Roll weight |
|---|---|---|
| Infinite Stamina | +50% | |
| Fit as a Fiddle | +25% | |
| Sickly | -25% |
Passives that move the same stat, nearest first: Infinite Stamina (+50), Fit as a Fiddle (+25) and Sickly (-25). A Pal can carry four, so the practical question is which four — breeding for passives covers how they are inherited.
There is an item for this one specifically — Disposable Implant: Eternal Engine and Implant: Eternal Engine— which changes a Pal’s passive rather than leaving it to breeding.
