Questions about the Heroes 4 map editor.

Treasuries are primarily taken for the money-resources; the artifacts in most of them (except for the dragon city) are not very valuable, although they can be useful. But you can also get the same artifacts without a fight from a skeleton. Therefore, I did not specify either the class or the chance of artifact drops. But I think the chance of a drop is close to 100%. For comparison, in the third game, the chance of getting an artifact from a skeleton is 20%, and in reality, it's even less. And in the fourth game, this chance is almost 100% (unless the enemies managed to loot it first).
