by Yeah, there's an elaborate crafting encounter in Wing 3 that takes an existing boss and makes him harder. It's triggered by a quest mechanic, and needs the recipe which is found in Wing 2. And a new epic resource from Wing 1, in addition to many of the familiar blue resources - including metallurgy and a base weapon. The resultant weapons are equivalent to tier 2, but they do a bit more DPS. This is because the new crafting encounter is the most challenging raid encounter to date.
So - need the item from W1, recipe from W2 and normal crafting items + base weapon...and use a something in W3 to make an epic weapon that is T2 equivalent but with a bit more dps. Sounds fun
