The market price is literally around 13,000tc...and there isn't much forum value either. Especially for shaman. Here is how I'm breaking down the prices:
Shaman - 1000tc
Platinum - 3000tc (market price is 10k which decreases in value as it's just a blood. Take vulcan blood for example, nobody is willing to buy a blood for 20k and I am also leaving room for profit).
