Ideas for increasing the popularity of Heroes of Might and Magic.

a little in defense of the artifact idea

If each clan has an artifact, and another clan conquers it

it's easily countered because to reclaim your relic, you can deploy any of your players and choose any player from the clan that holds your relic as your opponent (imagine how quickly they'll start getting rid of dead players :D)

We'll be without a relic... Or should we come up with several parts that make up a complete artifact?

yes, it's possible that initially there will be several sets that are divided among the clans

by collecting a set, you get a bonus
(wouldn't it be interesting to come up with some interesting artifact that gives a bonus on the forum? if not, then with such a dull imagination, there's nothing to suggest on the forum :))
