This is part of the Reign of Shadows Crafting and Housing Preview, written during the beta phase. As with all things beta, things may change before the expansion goes live. The RoS expansion will be released on December 15, 2020.

Once you finish the RoS Crafting Signature Line, you will be able to obtain and complete research requisitions from four different NPCs. Three of them reward a shared currency that can be spent in those three areas, and the fourth in Echo Caverns has a separate currency.

These research requisitions will be relatively straightforward, with only one extra detail compared to the BoL research requisitions. The RoS ones will also require a rare, which does not show in the initial harvesting quest. You will be able to see the rare in the recipe that has been autogranted when you received the requisition, and if you don't have one of the particular rare in your bags, then when you finish the harvesting of the commons, it will ask you to obtain the rare. This can be harvested, bought, grabbed from your depot, etc.

After you have all of the required ingredients, you craft the item requested and hand it in to receive 8 of the research currency (16 if you are a member), and a mission reward crate. You will also progress the current research a small amount.

Here are the items that can be researched:

Echo Caverns - Fivalt
