How paldb sources its data

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 Blood Is Fuel

No Pal is born with Blood Is Fuel — 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 Life steal

Blood Is Fuel gives +1%. 2 passives beat it, the best being Immortality at +5%. A higher number is better here.

All passive skills

Passives that move the same stat, nearest first: Immortality (+5). A Pal can carry four, so the practical question is which four — breeding for passives covers how they are inherited.
