"A… defensive technique. But effective. Use it if you do not wish to be hit, or if you are facing many opponents with blasters. With a lightsaber blade and enough skill in deflection, it is an excellent offence against blasters, but in other situations, it merely delays the inevitable."
The Way of the Mynock. A form of resilience and standing strong against the currents. This particular form emerged due to the invention of blasters, as the Jedi of old needed a way to be able to counter the new threat. The key to the form is one of subtlety and intelligence, as well as one of extreme patience. It is my belief that Soresu reflects everything a Jedi should be, and everything the Order stands for. It’s hard to remember the purpose of the Jedi these days…
The form is very similar to Makashi in the sense of motion economy, although with less of a focus. The movement of one’s blade is key, as you must be constantly moving your blade to use the momentum from previous parries and swings; thus minimising how much energy you use in a fight.
Patience is key, along with diligence. You must constantly hold your strong defence, no matter how great you think the threat is. Like a mynock draining the power of a ship, you must wait for the opponent to succumb to frustration and fatigue. Be patient and wait for an opening to present itself. Start to counter when their guard begins to slip and their will begins to falter.
The core of Soresu is the “eye of the storm”. Remain at the centre of the storm, and focus on nothing but your opponent and yourself. Do not worry about those around you or threats that are of no concern to you. One can be flexible and counter threats that are not emerging from their opponent, but you must never leave the eye. Stay calm, and steady at your center.
I once debated with Master Kenobi and some of the members of the council about if Soresu was the perfect form. And the undisputed Master of Soresu said this.
“Theoretically, Soresu is perfect in every way. But only if the user never misjudged an opening and maintained perfect, never-ending composure. Meaning that the opponent had to be imperfect, or the duellist themselves had to be absolutely perfect. Most times, neither are the case. Against an expert opponent, Soresu could exhaust the patience of all but the most patient of Jedi, leading to duels of tedious stalemates in a contest of who would make a mistake out of frustration or exhaustion first.”
To Summarise:
Remain patient. Eventually your opponent will slip up and become frustrated. Counter and parry, remain unmoved by your opponent.
Always keep your blade in motion to conserve momentum and not waste energy.
Remain in the eye of the storm. Turtling up and ensuring that you can defend from any angle with a stout guard. That is what it means to be in the “Eye of the Storm”
Its weakness is offence. A Soresu user can never go on the attack unless they have mastered the form. Incorporating offence into your Soresu before the opponent has left an opening leads to one outcome: Death.
Another weakness is the user themselves. If a Soresu user runs out of patience, they will fail. The humanoid temper being what it is in the heat of battle, many Jedi could be easily defeated by their own Soresu.
Finally, a cautious offence. If the attacker is cautious, the Soresu user may lose patience themselves.
