Effects

For an owner who can't benefit from it

The template gives these instead of the effects above when its “can benefit” check fails:

Prestige+0.25/month
Court grandeur baseline+5

Who can benefit (can_benefit) (6 lines of game script)

OR = {
	is_roman_emperor_trigger = yes
	culture = {
		has_cultural_pillar = heritage_byzantine
	}
}

As written in game/common/artifacts/templates (tree_automa_template).

History and who has it

Made before recorded history.
Kept with the title Byzantine Empire from 940.1.1.
At game start: the holder of Byzantine Empire (starts from 940.1.1) — needs Roads to Power.

How it is made

The game creates it with the scripted effect create_artifact_tree_automa_effect. In the console (how to open it), this gives it to the character you play:

effect create_artifact_tree_automa_effect = { OWNER = root }

Built from the effect's file; not run in the game by us.
