Was quite intresting in ArtifactPowerHelper.
Now (as asked there), i am looking for the trigger that tells items apart that can be used with the empowered Weapon and those items that are "too old and weak" and will trigger the "your weapon is too powerful" barrier.
Is it encoded in the itemlink like the AK multiplier maybe?
