The Azerite Knowledge system that periodically reduces the Artifact Power required to level up the Heart of Azeroth was originally intended to pause after this week. However, after considering feedback and looking at current Heart levels across the community, we’re extending it for another four weeks. The final increment until the upcoming Rise of Azshara content update will now occur with the weekly reset the week of April 23.
This change should give more players the opportunity to attain Azerite traits on current gear and reach the current maximum artifact level of 50 before the major Heart of Azeroth system update coming in Rise of Azshara. We’ll have more details on that soon.
