Gold in World of Warcraft: Classic can be earned with a bit of luck too. By killing and looting mobs you might find some truly rare items. Some of them might be usable by you but others might not. Don’t just sell that piece of rare equipment to the nearest vendor as it can earn you quite a bit in the auction house. Especially if it’s an item for a level 50+ character.
Furthermore, we highly recommend you plan in advance regarding the class that you want to play. In the Classic WoW, there were no class specs. Every talent point spent couldn’t be changed without first resetting all of them and the talent point reset was a costly practice. If you already know what you want to play as in the end game – try to develop your talent tree accordingly. This way you’ll be able to save a lot of gold in advance.
To get Blacksmithing to level 300 is much effort. It is not that thing to make fast gold. There is always a lack of Blacksmiths though. Enchanters need rods of all kinds, melee classes look for Sharpening Stones and Weightstones with Counterweights, others buy Iron Spurs. Once you have learnt rare and epic recipes, people will always use your service to craft items.
