Not sure, but I think you can only make it once since it's tied to achievements. No? I mean, I crafted Twilight but could only get Dusk once via the achievements. Now, if you used money to buy Dusk, perhaps you could make another Twilight? Not sure, haven't tried it. ofc u can because crafting leaf of kudzu is 500gold with achievemnt, in trading post 250gold, so logical thing to do is buy it from trading not doing with achievement
