While leveling I tend to get a lot of extra Kharma, especially from all those hearts and quests! What I do to make guaranteed gold (~1.2 Gold per 10k Kharma) from this currency can be summed up in a few screenshots...
1. Head to Sorrowful Waypoint in Bloodtide Coast.
2. Next, buy some Cloth Crab Grabbin' Gloves for 266 Kharam each.
3. Combine just these items into the mystic forge. Be careful not to combine any others that get created from this method.
4. Salvage the items that you receive for some easy linen. You can get cotton as well, which sells for about half the cost of linen. Also, there is a rare chance of getting items which you cannot salvage. Just combine those again to get a higher level item or vendor them.
You'll get a lot of essences of luck from doing this as well as make a profit. It's a win win!
I let blog subscribers and forum members know this trick well in advance of posting it here.
