When you activate stealth it looks like in a golden/orange smoke. The Sith basic lightning attack for Jedi is to hover a big piece of junk/rock from the ground and throws it to the enemy. The 3 second lighting Sith Attack for Jedi Shadows is like sending hundreds of small rocks to the enemy. The 8s Incapacitate skill (Tornado i think for the Sith) makes the enemy hover in air covered in some kind of force field.
I have a Jedi Shadow and full cloaks do not get along with the robe leg parts, when u walk/run you can see some clipping, robe lowerpart appearing above the cloak and such.
