Things You'll Need
Instructions
Purchase a large amount of either Whiptail or Twilight Jasmine on the auction house. Choose whichever herb is cheapest and ensure the number of herbs you purchase is divisible by five. On average, you will be able to craft one random Darkmoon card for every four stacks of 20 herbs you purchase. At a minimum, you will need 32 stacks of herbs; however, since the Darkmoon cards you create may belong to any one of four sets and the creation of duplicates is possible, you will most likely need a much larger amount to obtain all the Waves cards.
Purchase a large amount of Volatile Life on the auction house. To create a single Darkmoon card, you need 30 Volatile Life; at a minimum, you will need 240 Volatile Life; however, due to the randomness inherent in the process, you will most likely need a much larger amount to obtain all the Waves cards.
Mill all the herbs you purchased to obtain Ashen Pigment and Burning Embers.
Convert all the Ashen Pigment into Blackfallow Ink and all the Burning Embers into Inferno Ink.
Convert all your Blackfallow Ink into Inferno Ink through an inscription supplier, which can found near the inscription trainer in all major cities. The exchange ratio is ten Blackfallow Inks to one Inferno Ink.
Purchase the necessary amount of Resilient Parchment from an inscription supplier. The amount of Resilient Parchment you need is equal to your total amount of Inferno Ink, divided by 10 and rounded down. For example, if you have 175 Inferno Ink, you need to buy 17 Resilient Parchment.
Craft the Darkmoon Card of Destruction recipe until you run out of materials. This recipe creates a random Darkmoon card belonging to the Waves, Stones, Embers or Winds set.
Repeat this process until you have obtained all the Waves cards.
