One important feature of Heroes of Might and Magic is artifacts. Artifacts bestow special powers on their owners, enhancing that hero's statistics.
The effects of artifacts vary, depending on the artifact. Some artifacts enhance a hero's attack skill, while others increase a hero's defense. There are some other effects as well, but there is no need to list them all here.
I have divided these artifacts into logical categories, which you can see in the menu on the left. For example, the attack artifacts page contains artifacts that affect a hero's attack skill. The other pages are similar.
On the page for each category, there will be a short description to explain the effect of artifacts in that category.
