I didn't see a thread for this, so I'm making a new one.
We need to fix the Djem-So Moves feat, because of this:
Master Deflection (Trick): When using Deflecting Stance, you may deflect blaster bolts when using the Fight Defensively combat option.
Unlike the tricks in Soresu, this one interferes with the Lightsaber feat chain, since it duplicates (sorta) the benefit of Lightsaber Mastery's Knight Defense. Also, it has the same name as the Master Deflection in Soresu Moves while doing something different.
How about this?
Overwhelm (Trick): When you successfully attack someone with a lightsaber, that opponent is pushed 5 ft. away from you (unless the square is occupied or blocked, in which case he suffers 1d4 subdual damage). If this takes the opponent out of your reach, you may, as a free action, immediately take a 5 ft. step towards him.
Sort of a mini-Bullrush, and one of Vader's signature moves.
