Having a lack of astral diamond is a pain for low-level characters. You can't by gear or upgrade your enchantments. I was pulling out my hair until a saw a great video from Faid. Her process was easy to follow. I was able to score 5K astral diamonds a day. This may not seem like a lot, but it's a plenty for characters under level 20. I only did the run one to three time a day. If you run it more, you will make more money. The video is short but you can skip to 2:24 if you are impatient to get to the good stuff.
This is a great way to increase the number of node you can interact with. If you are trying to increase the number of diamonds you have, do this.
A Farm Run
Faid ran did a walkthrough of the Helm's Hold. It has a good route for rank 2 profession materials, You should be able to get through this run in 2 minutes. When you switch map instance you will start at the camp fire. Map sure to pick a map instance with the least amount of people. More people mean an increased chance someone else is doing a farm run.
What's Your Favorite Farm Run?
Helm's Hold was a solid go to for my low level characters. It's consistently earns when you price items to sell. Do you have a better area for characters under level 30? If so, let me know. I would love to hear about it.
