Please note: All prices in this document are spot prices, with large amounts of volatility. I take care but not responsibility.
There are not many trinket makers on our AH at the moment - maybe 10 toons. Admittedly we are mid cycle for the darkmoon goblins, but I have seen one or two players dominate the glyph market which has many more players. According to the undermine journal, the number of players has not changed much.
Between individual cards and the final trinket, you have a completed deck
- Hurricane : 4 decks @ 15,000g (winds)
- Volcanic : 3 decks @ 15,000g (embers)
- Tsunami : 3 decks @ 17,000g (waves)
- Earthquake :1 decks @ 8,000g (stones)
The final product of the darkmoon cards are (with undermine journal numbers and prices):
- Hurricane Agility : 2 cards @ 21,000g
- Hurricane Strength : 3 cards @ 19,800g
- Volcano (Caster DPS) : 1 @ 20,500g
- Tsunami (Healer) : 0. Average 32,000g
- Earthquake (Tank) : 2 @ 12,500g
With the above prices. I will either sell individual cards, or complete decks and turn them in and sell the completed trinkets. I will only complete decks during the faire. I am also buying completed decks for turning in too.
I started off with an investment of about 17k, and ended up with a (potential) profit of 45k. This is a huge return, and given the difficulties that some players have expressed in selling trinkets, I expect that this level of profit is unsustainable. There are also new trinkets being released in 4.1 that will also depress prices.
All in all, I am surprised at the value in crafting these cards. With the reputation reward from Tol Barad being two reputation epic trinkets (one mastery and another role specific), I had expected more players to grind rep rather than pay gold.
But this type of surprises is why I did this research. This is a nice way to make extra gold.
