Max-level players in this build may notice an important new Artifact feature. The researcher/scribe NPC in your Class Hall will offer you a quest to retrieve a set of tomes from around the world. Once these are recovered, you can instruct your researcher to work on deciphering these tomes. Each step of research will require some Order Resources (which are primarily obtained through World Quests), and will grant increased "Artifact Knowledge."
Increasing Artifact Knowledge permanently increases your rate of Artifact Power gains, and this bonus applies to all artifact weapons your character may possess. (And no, Artifact Power items obtained at a lower Knowledge level won't automatically update, so hoarding items for future use won't benefit you.) This system is key to the pacing of overall artifact progression, and to making it easier for players to maintain multiple artifacts if they so desire. For example, at Knowledge Level 7, you would be earning Artifact Power at over triple the base rate. Thus, if you wanted to switch to a spec you hadn't yet tried at that point, you'd find yourself very quickly able to get that artifact up to par with your primary one.
As your scribes progress through their translation and research, you will fill in pages of a great tome in your Class Hall that provides more backstory and information about your artifact (this is not yet fully hooked up for some classes). Finally, in the live game, the speed at which your researchers can work will increase as the expansion progresses, allowing latecomers or alts to catch up on their artifact progress.
The tuning of the experience and Knowledge curves is still in flux.
