|-
| '''cost = <int>'''
| style="text-align: center;" | {{icon|yes}}
| The cost of this trait.
| Leader traits do also have "costs", see [[Leader modding]] for details.
|-
| '''icon = <gfx file path>'''
| gfx/interface/icons/traits/<trait key>.dds
| Alternative icon of this trait. gfx/interface/icons/traits/<trait key>.dds
| Leader traits always have this property specified because their icons are stored at "gfx/interface/icons/traits/leader_traits/xxx.dds".
|-

| style="text-align: center;" | yes
| If no, this trait cannot be picked in the empire creator and it cannot be added to a species template.
| If no, this trait cannot be given to a leader upon leader generation.
|- 
| '''randomized = <yes/no>'''
| style="text-align: center;" | yes
| If no, this trait can't be picked by species random generator.
| It's still unclear, because {{iconify|Armchair Commander}} has <code>randomized = no</code> but can stll be given to a newly generated leader.
|- 
| '''modification = <yes/no>'''
| style="text-align: center;" | yes
| If no, this trait cannot be added to or removed from a species template.
| It's still unclear, because leader traits always have <code>modification = no</code>.
|- 
| '''improves_leaders = <yes/no>'''
| style="text-align: center;" | no
| If yes, this trait will have a tooltip that says leaders from this species will have traits that enhance them. Actually, those leader traits must be implemented elsewhere.
| rowspan=4 style="text-align: center;" | {{icon|no}}
|- 
| '''advanced_trait = <yes/no>'''
| style="text-align: center;" | no
| If yes, this trait is considered an advanced trait and can be added to or removed from a species template only if the empire has researched any technology with the feature flag "add_advanced_traits".

This permission overrides <code>initial = no</code>, but doesn't override <code>modification = no</code>.

|- 
| '''valid_for_all_ethics = <yes/no>'''

| '''sapient = <yes/no>'''
| style="text-align: center;" | yes
| Vanilla pre-sapient traits have <code>sapient = no</code>. Seems to allow the trait to be selected by <code>trait = random_presapient_trait</code> in a <code>create_species</code> effect
|- 
| '''immortal_leaders = <yes/no>'''
| style="text-align: center;" | no
| If yes, leaders from a species with this trait will be immortal. This will also generate an entry of "{{green|Immortal}}" in tooltip.
