Red Nemesis
The Blind Critic
I don't mean to throw this thread off topic, but it seems to have died anyway. This seems like the ideal place for a definitive discussion about what Vaapad does and does not do.
Case 1:
Vaapad practitioner vs. Dark Side User
This is the most common instance in vs. Threads- See Mace vs. Palpatine. In this situation, the 'superconducting loop' comes into effect. In the only canon case of this occurrence, Vaapad was thrown against a superior force user (Sidious). The Superconducting loop serves to equalize the disparity between the Vapaad user and his opponent. This only comes into effect with Force powers- it copied Sidious's Force Speed, but would not be able to copy someone's innate speed- like Grievous.
Case 2:
Vapaad Practitioner vs. Neutral user or non- Force Sensitive
This is probably the most common occurrence in universe, as there are fewer DS users to fight than say, droids. In this situation Vaapad is fueled by the user's inner darkness- the innate power of Mace Windu, for example. The 'loop does not come into play, but the user still 'skirts the penumbra' of the DS, as shown by Shatterpoint. This is the style that Windu uses in any fight where he is not outclassed by a DS force user.
Case 3:
Vaapad Practitioner in a Sparring setting
The consensus on the boards is that Vapaad does not automatically use the metaphysical aspects of the style in a fight. The combinations of the saber style, the sequences, would be unaffected by the users 'mood'. I take issue with this idea.
Vapaad was not just a saber style-it was a state of mind
There was no Jedi restraint here.
Mace Windu was cutting loose.
Vaapad is a channel for darkness
Vaapad is as aggressive and powerful as its namesake, but its power comes at great risk: immersion in Vaapad opens the gates that restrain one's inner darkness. To use Vaapad, a Jedi must allow himself to enjoy the fight; he must give himself over to the thrill of battle. The rush of winning. Vaapad is a path that leads through the penumbra of the dark side.
This shows that to use Vaapad at all, one must enjoy the battle, and to do so one must fight the lure of the Dark Side. Simply using the form on Karun Hal (without a lightsaber in his hand) pushed him dangerously close to the Dark Side:
He knew already he could not match Vastor for raw power. With each breath, he stripped away another layer of restraint and inhibition. Another layer of serenity. He had to move his inner peace out of the way to let in the joy. The thrill. the sheer okay-why-not-let's-FIGHT. Because Vaapad was more than just a form os Lightsaber combat.
It was a state of mind.

To use Vaapad now, out here was incredibly dangerous-almost as dangerous as not using it.
You can't get Vaapad results without using a Vaapad state of mind.
