How do you get Ancient Aruval with the console?

effect create_artifact_aruval_effect = { OWNER = root } — runs the scripted effect that makes it, for the character you play (debug mode).

What if the owner can't benefit from Ancient Aruval?

They get Court grandeur baseline +3 instead.

History and who has it

Made before recorded history.

How it is made

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

effect create_artifact_aruval_effect = { OWNER = root }

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