NOTE: You will need a Jedi with a lightsaber for this!

Do you know those droid that roll in the balls and have the sheilds Did you ever want to kill them easily Well it is very simple! The only objective is that you will need a Jedi with a lightsaber to do so. Then when you are battiling a Destroyer Droid, do the dropping lightsaber trick ( when you jump and force the lightsaber to the ground ) on the droid. The sheild will go down after one or two times! Then will will easily be able to kill it!
