Swgoh farming flowchart

B1 Battle Droid is the first farm recommendation that comes from a chapter 5 node. Chapter 5 of Fleet Battles is very hard, and I recommend striving to unlock them as early as possible, but that's not always going to be easy to do. Below you'll see an option to skip to the next chapter 4 or earlier requirement, should you need more time to strengthen your fleet for chapter 5.

B1 Battle Droid is on 5-B.
