I finally finished the crafting quests in all the worlds EXCEPT dragonspyre. Only to find out I need Black Lotus and diamonds. When i go to the vendor they don't sell them! So my idea is being able to buy ALL the regents, since they never are around in the bazaar, and no matter how much I search I find nothing!
can't you transmute black lotus from cattails and...something else? Get a card crafting table. Then buy the recipe from your quest giver. There is a little arrow at the top right where you can change from buying equipment recipes to buying reagent recipes. Just make two black lotus a day for ten days.
