Artifact Knowledge can now be researched to a maximum level of 40 (was 50). Developers’ Notes: We raised the Knowledge cap from 40 to 50 very late in the 7.2 PTR cycle, out of an abundance of caution: We wanted to ensure that players of all playstyles, as well as alt characters, would view the Concordance trait as accessible. However, between the additional Artifact Power gains added in 7.2 and others that were hotfixed in after the patch released, we’re now well ahead of that mark. Knowledge 40 now seems more than sufficient for players to reach Concordance, and the prospect of months’ worth of additional Knowledge still left to research makes some players feel like their efforts in the interim aren’t meaningful. Therefore, we’re rolling the cap back to 40.This means that the cap will be 4,001,000% AP insted of 55,200,100% AP
