Force Pull cannot be used against a character with Shrouded. Pull is an ability that targets a character (the word target is in the ability). The acting character then gets to attack the targeted character.

Any ability (CE or SA) that chooses a target cannot choose the Shrouded character. Since the vast majority of abilities follow the targeting rules, it's probably easier to list abilities that *can* be used against Shrouded.

* Most Abilities that generate attacks can be used. When an attacks are generated (like Lightsaber Assault or Lightsaber Throw), the target of the ability is the acting character - receiving the benefit of getting to make attacks. The enemy is the target of the attacks, not the target of the ability. Since Shrouded doesn't prevent attacks (or targeting for an attack), Shrouded doesn't prevent Lightsaber Throw or Lightsaber Assault or Galloping Attack or Lightsaber Sweep or Strafe Attack.

* Grenades, Flamethrower, etc can affect the Shrouded character if they are standing next to the target, but they can't be chosen as the target themselves.

* Event Manipulator does not target, so a Shrouded character (or even a Diplomat) can be selected.

* Levitation does not target.

* Force Repulse, War Throat, and other area effects do not target.

I probably missed a few, but generally, if you're choosing an enemy (especially using the targeting rules), you're choosing a target (unless the glossary says otherwise). If you aren't targeting the enemy for an attack, then you're probably targeting the enemy with an ability... and can't choose a Shrouded enemy if you're within 6.
