Darth Subjekt
The beginning of the end.
Form II: Makashi "Way of the Ysalamir" or "Contention Form"
Form II represents the ultimate refinement of lightsaber-to-lightsaber combat. Masters of Makashi develop unique offenses and defenses and train studiously against having their sabers taken or damaged.
Form III: Soresu "Way of the Mynock" or "Resilience Form"
Form III was first developed in response to the advancement of blaster technology in the galaxy. Soresu's emphasis on tight, efficient movements that expose very minimal target areas, make it the most defensive and passive of the seven forms.
Form IV: Ataru "Way of the Hawk-Bat" or "Aggression Form"
Form IV is the most acrobatic of all the forms and requires a Jedi to first master the Force Run, Jump, and Spin abilities. By incorporating all the Force powers that allow a Jedi to exceed standard norms of physical abilities, Jedi may resemble nothing less than a blur when using this style.
Form V: Shien / Djem So "Way of the Krayt Dragon" or "Perseverance Form"
Form V was also created in response to the advancement and frequency of blaster use in the galaxy. Unlike the strictly defensive style Soresu, Shien exploits the ability of a lightsaber to block blaster bolts and deflect them back at an opponent in a counter-attack maneuver.
It seems that even Advent can mistake a word or two at times. I must say that these descriptions have been updated since the last time I looked at them and are far different. In any case, Soresu was created for that purpose and given a Jedi and his pre-cog, I see no reason why he wouldn't be able to deflect bolts back at the user.
However, they still have the force and could wipe them out with that. "Don't be so proud of this technological terror you've constructed. The ability to destroy a planet is insignificant next to the power of the force."
