When doing the Sandral-Matale Feud quest, go to the Sandral home first when you have permission to investigate the disappearance of Shen Matale from the Jedi Council. Take the necessary steps to enter the home. After questioning Nurik Sandral, he will depart to the back of his home. Get to the point where you can deny Rahasia. You can go to the Matale's home and speak with him. If you select all the bottom answers, his last question will be for you to ask 2,000 credits for finding Shen. By selecting all the bottom answers, you have earned yourself a Dark side point. Talk to the droid again and Ahlan Matale returns outside with the same line of questioning. Repeat this to accumulate as many Dark points as desired.
