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.
Pals born with Ace Swimmer
No Pal is born with Ace Swimmer — it can only appear as a rolled trait, or be 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 Swim speed
Ace Swimmer gives +40%. Only King of the Waves beats it, at +50%. A higher number is better here.
| Passive | Swim speed | Roll weight |
|---|---|---|
| King of the Waves | +50% | |
| Sleek Stroke | +30% |
Passives that move the same stat, nearest first: King of the Waves (+50) and Sleek Stroke (+30). 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 — Implant: Ace Swimmer— which changes a Pal’s passive rather than leaving it to breeding.
