Traits

Traits are passive bonuses for creatures, similar to synergies, although traits are permanent bonuses while synergies will be removed from creatures after each run.

Trait Points and Slots
Every creature starts off with 1 trait slot at level 1 and may unlock an additional trait slot after each level up for a maximum of 6 slots at level 6. When a new trait slot is unlocked the player can use one of the creatures trait points to choose between 2 different randomly generated traits, each with their own randomly generated maximum trait level (1-5).

Trait points are obtained based on how often the player uses a creature. The more the player uses a creature the faster it will obtain trait points.
