Artifacts are hero specific items purchased with Gate Points at the Hero Altar. Artifacts are rare and powerful weapons that empower your generals with unworldly might.
Each Hero has a choice of 6 artifacts, 2 of which are have a limited number of charges and are disposable. The other 4 permanent items are exclusive pairs, such as two swords and two armors, or two robes and two scepters. Heroes cannot use two of the same type of item (i.e. hero can equip one sword but not two).
Artifacts are designed to play to a heroes strength and allow players to further customize their hero power growth across the game.
