We have just released the next tier of crafting - level 7! To access this, load the latest dataset and upgrade your Crafting Workshop to level 7. You will see all new hero equipment to craft.
There are also a few (not limited time) quests related to this - just scroll down past the limited time quests to see them.
We've also increased the number of materials being given out in crates to 2! This applies to the Wanderer's Crate, Exotic Ingredients, and Alchemical Oddities. The quantities in the Materials Shipment has also been doubled.
