Index Stun

Force Cost: 20
No Effect on Droids
Fittingly, the Light side has few powers that inflict direct damage upon an opponent, instead focusing on disabling an opponent's defenses, allowing your characters to more easily damage or kill the enemy. Stun fits into this philosophy well; if the enemy fails his or her saving throw, they'll lose any dexterity bonuses to defense, and sneak attacks from your scoundrels will always work (assuming the attack hits), no matter from which side of the target they originate. Even so, stun doesn't make the jump into area-effectiveness until the third rank, so you might want to stick with Force whirlwind for large groups until you access stasis field at level 15. Stun does not work on droids; they get their own special stun droid power

Stasis	Level 9	Target is stunned for 12 seconds Save versus fortitude: target is slowed instead of stunned for the duration

Stun Droid

Force Cost: 10
Since you don't run across quite as many droids as you do human opponents during your journey, it makes sense that stun droid would wind up being a bit more powerful than the regular stun power, but you could make the case that it actually goes a little too far: once one of your characters accesses the third level of stun droid, even the biggest and baddest of the mechanical monstrosities won't threaten you again. You see, unlike stun, destroy droid offers no saving throw to the stunning effect itself, so that anytime you use this power on a droid, it will have no choice but to shut down for a short period of time, while you and your teammates will, of course, be trying not to get flying metal in your eyes while ripping said droid to pieces. What's more, the power penetrates droid energy shields, rendering even the most powerful opponents to so much scrap metal for you to demolish.

Destroy droid is perhaps the most useful Light side power, after cure.

Bottom line: get at least one character to the third rank in this skill, preferably your PC, just so you'll always have it available. At the second and third ranks, the power is area-effect, enabling you to shut down a whole group of droids, turn to attack the human opponents, switch back to stun the droids again, and so on. Fights against droids alone are even more ridiculous; just queue up three destroy droids and almost any droid in the game will be dead by the time you need to queue anything else, since there's significant direct damage on top of the stunning effect.
