That makes sense now.
Personally I think that was lame, they should have had an option to attack the pods directly with a lightsaber.
I just attacked HIM with my lightsaber, again, again, and again.
Damn fool kept regenarating whilst i kept removing parts of his anatomy.
It wouldn't have been so bad if he had just accepted defeat the first time, he had to be a loser 7 times over, bah.
What's really sad is the only way they could make that fight even remotely challenging (and I use the term loosely) was to give him that regeneration method.
The whole Star Forge was a mindless grindfest.
