If you just started playing tera online there is a really easy way to get a lots of gold. When you start questing there is a really important quest that gives you the item: Volunteer Supply Crate. The quest is called “Making the Rounds” and is given by NPC law on the island of dawn.
The volunteer supply crate can be opened every 5 levels and will surprise you with some awesome items. On level 30 and level 40 you will be rewarded with some enchanting material called: Extensive Alkahest. You will get a total of 55 pieces. Make sure you do NOT use this material to enchant your gear.
Go to the broke trader NPC and go sell your extensive alkahest for 280 gold per piece. This will give u a total of 15400 gold!
