- Search for fiendish creatures. You can sell gems and slivers, both pay well.
- Do warzone tasks. You can do them solo every day and sell crystalline tokens, silver tokens and whatever else you get.
- Do warzone bosses: You can do them every day, but you need a team. In most worlds, people do them at some specific time of the day. Ask in the world chat for what is the time people go to warzone in your world.
- Resell items from the market to NPCs. Often players sell items for a lower price than they are worth for in NPCs. They do it to save their time. For example, you can buy boots of haste for 29k from the market and resell it to blue djinn for 30k. (You can also put your own buy orders.)
- Resell houses. You can be on top of the house auctions in your world and buy houses for a cheap price while they're auctioned, and then resell them directly to players for a higher price.
- Sell quest and outfit items in the market. For example, you can produce document of the follower/officer/leader and sell them in the market; you can also collect and sell dwarven pickaxe and other similar items players want quickly when they're questing.
