Stellaris 4.5.2 species traits

Stellaris 4.5.2 has 363 species traits in its files; 186 can be picked when a species is created, the rest come from genetic and robotic modification, ascension, events and origins. Positive traits cost points, negative ones give points back; opposite traits exclude each other.

Species traits: questions

How many trait points does a species get in Stellaris?

Biological and lithoid species get 2 points and 5 trait picks, machines 1 point and 5 picks, mechanical (robot) species 0 points and 4 picks (common/species_archetypes); negative traits give points back. A species class can set its own numbers.

How many species traits are there in Stellaris 4.5.2?

363 in the files, 186 of them offered at species creation.
