Spar with the Handmaiden for the second time (For me this was on Nar Shadda, after killing the mercenaries leveling to a prestige class but before going to any other planet). Agree to the conditions of the duel*, which are no items, lightsaber, or force powers(nor can you wear armor but she doesn't mention this; man is this game buggy). Let the duel begin, and immediately use a force power. She'll stop & say you violated the terms of the duel. Explain to her that you were trying to teach her something about false situations & imposed limitations. You can bring up her father, whatever, be mean or not, just make sure you tell her at the end of the conversation that you were just trying to teach her something. You'll get +INF+. If you offer to duel her again, and break the rules again, you'll gain more +INF+. Huzzah! Man was this thing rushed out the door.

You can say "I only wanted to teach you a lesson, humiliating you is just a bonus." at the end of the conversation for infinite DSPs in the same manner.

Note: If you have a lightsaber equipped, the game will crash at the end of the dialogue.
