Pendant of Merged Destinies - the artifact is fully implemented.
Divine Scepter of Sar-Urazir - the script is currently being written.
I also plan to create a third artifact; probably, in the 2nd mission of the Campaigns, these 3 artifacts will be offered as a choice, as a starting bonus; the choice of which artifact to upgrade, as it seems to me, will seriously affect the game strategy.
Thank you for your attention;)
