I love the Death Embrace artifact set! But unfortunately, I couldn't collect the complete set in the game, although I managed to collect 3 out of 4 pieces.
All artifacts drop according to an algorithm – one piece from a set appears in one shop (finding artifacts from sets, like the Necromancer's Amulet, is practically impossible on the map). The system works like this: you, located on your territory with one shop, get one of the artifacts there, for example, the Crown of the Dragon, while your opponent, with a shop on the other side of the map, sees an artifact from the same set, but, for example, the Sheath. (Of course, these artifacts can drop at different times). Utopias remain... There, of course, they can give you anything... So, it turns out:
1. 10% chance that you will capture all the shops and not miss a single artifact.
2. 10% chance that you will find a Utopia that gives you the desired artifact.
3. And another 10% chance that you will find the desired artifact on the map.
In total, it's about 30%, which is insignificant for collecting a set... This is not serious, and you can't rely on it.
Of course, all this is just my opinion (IMHO)...
Sincerely, _Prizrak_
