Passive Traits

A companion may carry one passive trait, and it applies wherever that companion is used. The effect line under each trait states exactly what it does.

The catalogue

Bountiful

A knack for coming back with more of everything from an expedition.

+10% expedition yield (stacks per squad member)

Chance when newly rolled: 12.50%

Driven

An insatiable drive to improve; earns bonus experience for itself from every expedition and incursion floor it clears.

+15% XP for this pet from expeditions and incursion floor clears (does not affect other squad members)

Chance when newly rolled: 12.50%

Fertile

Improves the odds of a mutation when this pet breeds.

+10% mutation chance when this pet breeds (a second parent with the same trait adds nothing)

Chance when newly rolled: 12.50%

Keen Eye

Sharper senses turn up rarer finds on expeditions.

+10% rare-find weighting on expeditions (stacks per squad member)

Chance when newly rolled: 12.50%

Lucky Roll

Rolls a share of the squad's dice twice in an Incursion and keeps the better face on each.

Rerolls up to 50% of the stat-derived Red/Green/Blue Incursion dice in the squad and keeps the higher face on each, scaled by how much of the squad carries this trait (never Gold dice)

Chance when newly rolled: 12.50%

Lucky Star

A star-blessed pet; grants a permanent Gold wild die at the start of every Incursion, the same as a Celestial Marking.

+1 permanent starting Gold wild die in an Incursion (stacks with Celestial Marking)

Chance when newly rolled: 12.50%

Stoic

Unbothered by circumstance; doesn't get shaken by repeated failure as easily as other pets.

Counts at 0.5× weight toward a party's Void Sickness sick-majority gate when sick, instead of the normal 1×, and needs 2× as many consecutive Fails to reach the un-diluteable deepest tier

Chance when newly rolled: 12.50%

Wanderlust

Always looking toward the horizon; better odds of stumbling on a Vista out on expedition.

+5% chance to discover a Vista on expedition collection (stacks per squad member)

Chance when newly rolled: 12.50%

Where a trait comes from

  • Starlight Nesting. A newly nested companion has a 40% chance to inherit Parent 1's trait, 40% for Parent 2's, and 20% to settle on a fresh one from the catalogue above.
  • A Prism Refraction. A companion with no parents settles on a fresh trait using the catalogue odds shown above: the same weighted pick as the 20% branch above.
  • Re-rolling. A Legacy Echo infusion on the companion's page (150 🎐) swaps the trait for a different one. The result is random but is never the trait the pet already had, so a re-roll always changes something: though it can still land on one of the no-effect traits above. Each companion can only be infused 2 times total, shared between a trait re-roll and a stat-ceiling boost, so choose when to spend one.
