Look, I know you are trying, and you have some good ideas, but you have to pay attention to what you write. The death eater that Harry first cuts? He is bleeding. From a lightsaber wound. Really?? I also think your combat scenes have no oomph, flash, or urgency. Honestly, you have made Harry invincible, not super.

Thank you for your comments. I'll deal with them one at a time.
The lightsaber is an energy weapon but it only partially cauterizes the wounds. The death eater is bleeding because Harry cut off his arm. (Reference the cantina scene in ANH.)
Oomph and flash: Have you ever been in a gunfight? I have. Harry is handling the combat like a professional would. The same goes or Dobby. they have a job to do, and little time to do it.
I have not made Harry invincible. I have made hm a Jedi.
