Star Trader With Bubble Columns (More reliable)

I used a technique found in most mob farms to create this method of getting Star Trader. Decided to go with a visual tutorial/showcase. The advancement may change in development still, but we will see. I'll update these videos if any changes are made.
The unedited video is about 5 minutes.
