Luke's Growth Between ESB and RotJ
As we know, the Luke who was being toyed with by Vader, and the one who beat Vader into submission, are on very different levels of ability. How much do we know about Luke's growth in between episodes? As in:
- What training did he engage in?
- What combat experience or other relevant experience did he pick up?
- When did he make his new lightsaber?
Also, I can't remember if Yoda kept training him after ESB or if he took ill before he could finish. In any case, how much do we know in:
1. Canon
2. Legends
