Yesterday I noticed that the two main champions that I use, which are equipped with a set of LIFESTEAL artifacts, were not gaining any hp when they attacked enemies. At first, I thought maybe I had mistakenly changed artifact sets but this morning I looked them over and realized that nothing was different. Maybe I don’t understand how these artifacts work, but I assume that they are supposed to work the same ALL the time.  Please let me know if I am doing something wrong or if there is a bug somewhere. This is really affecting my progress. Thanks guys and I am really enjoying this game.
