Oh one more thing, everyone re-sets their Force Point pool to 5 + 1/2 (round down) their Heroic character level. So everyone would go over to 6 Force Points now.
As for dismemberment
well there is a Jedi Knight Talent (you need to be 6th level to take it) and it reads like this...
Severing Strike: When you deal damage with a lightsaber that is equal to or greater then both the target’s current hit points and the target’s damage threshold, you can choose to use this talent. Instead of dealing full damage, you instead deal half damage and the target automatically gains the Stunned condition. In addition you sever one of the target’s arms at the wrist or elbow joint or one of the target’s legs at the knee or ankle joint (your choice). Severing part of an arm puts the target at Disadvantage for Strength and Dexterity skill and ability checks. Severing part of a leg knocks the target prone, reduces the target’s speed by half and imposes Disadvantage for Strength and Dexterity skill and ability checks. These effects are persistent, although a target can learn to somewhat compensate and lose the Disadvantage on skills and ability checks that can be performed one handed (GM’s call). Otherwise the only way to remove these persistent conditions is with a cybernetic replacement.
