Every time you engage in a swordfight, use only the hammer or little scorpion moves. These are easy to pull off, and will give you respect each time they hit. If your opponent is dodging these attracts, which some do, then hit him or her a few times with another attack to bring him or her to about half health. Then , attack away. The opponent might block your attack, but it is very powerful and will break their sword after a few hits. Note: This does not work for every fight. For example, against Harry as his sword is unbreakable. Also, it will not work if you do not have an offhand sword equipped.
Never kill an opponent after a duel. If you let them live, you will get a lot of respect, and they often open up secrets for you.
As soon as you learn how to focus, start to use it. When in combat, focus as soon as you can and shoot the guns out of your opponent's hands (aim inside the white box). Then, shake the Wiimote Up and Down to disarm them. This will take them out of combat and give you about 50 respect per enemy. Also, if there is a leader in the room (an enemy with a circle above his head), disarm him immediately to make all other enemies in the room disarm, giving you a huge respect bonus.
To increase your focus quickly to disarm opponents, use the Uzi. It fires a lot of bullets that do not do a lot of damage. Therefore, if you are out of focus and want to disarm someone, shoot them with the Uzi for awhile. You should get enough focus back to disarm them without killing them. Try doing this if a leader comes in the room and you are out of focus. It makes tough rooms a much easier.
