Card of Omens are cards that can be crafted and then “flipped” by using them. The flipped card will be one of several blood cards with values ranging from 1 copper to 6000 gold. Large sample sizes of flips indicates that the value from flipping and vendoring the cards is most likely somewhere above 4,5g per card. The redditor Schrobbert made the definitive post on this back in June. As we can see from the reddit post the method is profitable when herb prices are 1g or below. His assumptions are a bit conservative as well as he just calculates 2 pigments per mill, which is quite a bit below the correct 2.3725
I compiled the current median prices on WoD herbs for both EU and NA in the table below.
As we can see with current prices this is gonna be profitable across the board in both regions. As noted on reddit however you need to move a very large amount of herbs into Cards for this to be worth it.
The requirements are very simple. You learn the recipe from using the Draenor Inscription scroll. This can be bought from the Inscription trainer in your factions Ashran base. It requires level 1 inscription, so there is zero prerequisite for the craft. The biggest requirement for doing Card of Omens is to get enough herbs. You need to flip 20 000 cards at least to feel reasonably certain that your yield is around the average.
The general process for crafting Card of Omens is quite simple. One stack of 10 cards costs 5 War Paints (The WoD Inscription daily CD) and 10 Light Parchment. You can see the process outlined below.
- Buy herbs: Just buy all WoD herbs you can find below 1g each
- Trade Herbs for Primal Spirits
- Mill herbs: No comment needed
- Craft War Paints with your daily CD
- Craft Work orders
- Primal Craft all your pigment into War Paints
- Craft Cards
- Flip Cards
- Vendor Cards
The first 5 points should be quite straight forward, with the Exception of #2. To trade herbs into Primal Spirits you need access to a level 3 Garrison. In your Town hall there will be a rotating NPC. Some of these NPCs are the traders. Specifically for this we want the herb trader. At this trader you can exchange 5 of any WoD herb for one Primal Spirit. With Primal Spirits you can craft War Paints with the Spirit of War recipe, This turns 4 pigments and one Primal Spirit into 2 War Paints. Doing this you can craft War Paints without being limited by the daily cool down, and actually reach the number of cards you need to craft.
So let’s do some math on the crafting cost per card in terms of herbs. We know 2.3725 herbs is equal to 1 pigment. The cost of 1 War Paint when primal crafting is 2 pigments and half a Primal Spirit. War Paints are therefore valued at 7,245 Herbs. We can then divide this by 2 to get the herb cost per card which is 3.6225. With the value of a card being 4.5g or higher with herbs at 1 gold you are making on average one gold per flipped card. As we see from the quoted prices this just gets better with cheaper herbs.
Mass crafting – issues and tips
This method is not for people who are not into clicking buttons. It requires a very large number of crafts. As we can tell from the reddit thread you need to flip at minimum 20 000 cards, preferably 5 times that amount. This equates to 3.6 times that many herbs. You also need to patiently wait around for the herb trader so you can turn your herbs into Primal Spirits.
I strongly suggest flipping the cards with a second account if you have that. You can use AutoHotKey (You can find a script for WoW here) to send keypresses from your main and just keybind all the buttons on your flipping account to a simple /use Card of omens macro. Or you can flip on both accounts while doing something else. After flipping the cards you just sell them all to a vendor.
You should not reflip the cards that can be flipped again as this is always negative value.
As we can see from the process you can also make war paints from the daily cooldown and work orders. This is more efficient than primal crafting. The cards can be crafted by the NPC in the inscription hut in a garrison even if you don’t have inscription. This means that the Scribe’s quarters is a very nice building to have in all of your garrisons as it will provide some very simple extra profit.
Profit margins on these will be even better as a war paint only takes 2 pigments, which means each card will cost 1.25 herbs less. This puts you at 100% profit margin at 1g per herb. It also means that you can tolerate smaller sample sizes.
I only really endorse mass crafting Card of Omens for people who enjoy crafting very large amounts of items, the rest of you should stick to the daily cool downs and work orders on any relevant alts you have hanging around. I have personally done some decent samples using a ton of herbs I bought around Legion launch and I find the process decently soothing. That being said your mileage might very well vary.
The gold is fairly easy and guaranteed and can be easily combined with watching a TV-show or similar. Given that it is a vendor shuffle the only real risk is not crafting enough cards, and you can control that.
