Oh my f***ing god. That is so much bullshit that I won't waste my free-time by going through this point by point.
Amulet? Sith Magic? Why DS can't get simple point...
Really. Contrary to your assertions, which must be you "playing dumb" (at least I hope so) I didn't state that the amulet has anything to do with the attack that Kun hits Aleema with. I was merely pointing out that instead of raising his left hand and firing that Sith Magic attack at Aleema, Kun could also have lifted his right hand and fire an amulet blast.
Can you follow so far? I hope so.
Now if Kun is able to dash out force attacks while simply walking through opponents attacks or, seeing the action with Odan-Urr, can recover from devastating force attacks in the matter of seconds or, as seen, can jump around that nice Sith worm while firing his amulet, I don't see how anything Mace or Dooku could do - force wise - is going to stop him from using the amulet or any other force attack he can come up with?
Is that clear now? Did you get it? Or do I have to find somebody who speaks fluent moron?
Odan-Urr and Aleema Keto? Are they powerful?
One must love your sudden amnesia concerning Odan-Urr, Sexy. I mean what is this here?
Oh yes. It's Odan telling Nomi that he became adept to blocking somebodies connection to the force when the Jedi drove the Ancient Sith to extinction. Your comment regarding FotSE is absolutely hilarious in this context. Unless you want to tell me that the complete Sith race, inhabiting more than 100 planets, was either fighting on 3 planets with Sadow or manning the fleet of Ludo Kressh that Sadow confronted when he returned.
So Odan did confront Sith Lords in combat and blocked their connection to the force. And usually, Jedi don't get weaker in force abilities when they reach higher age. Odan was physically weak perhabs which might have made it easier for Kun to kill him. But the initial attack of the Jedi, which Kun simply resisted, must have been quite powerful.
And regarding Kreias comment: Excuse me Sexy. Can you please at least attempt to form a coherent argument? Either all in-universe sources (characters, holocrons, texts etc.) are questionable - or none is. You can't pick the ones that fit your opinion and scream "canon" or "retcon" and ignore anything else at will. That doesn't work. If the holocron must be correct, the same is the case for Kreia. End of story.
That leaves us with Aleema Keto. Did it ever occur to you that Nomi Sunrider, one of the eras prodigies, had apparent problems with countering Aleema's illusions? That aside, it still requires some nice amount of force powers to instantly burn off the skin of a human being - no matter if the victim is a force user or not. Not to mention that the narrator of DLotS lists Aleema as a "potential rival" to Exar Kun and she gives Ulic the Sith amulet stating that it "perhabs will give [him] an advantage over [her]", implying that Ulic and her were equals at that point in time. Is that powerful enough for you?
The Double Blade - what sources can we thrust?
And now let's get to the core of the pile of bullshit you've produced this far.
You are aware of the fact, Sexy, that holocrons aren't sources containing material from some omniscient beings, correct? They contain recordings of individuals within the SW universe. In this case, we have the Tedryn Holocron which is a Jedi holocron. So what we have in JvsS is an in-universe-character (Tionne) accessing stuff that other in-universe-characters left behind. Enough for a retcon?
Nope. There are multiple reason for that. The main reason is, of course, that this source is contradicted by two omniscient out-of-universe sources that state Kun did design the weapon. Unless they are contradicted by a source of equal nature or higher canon, that stands - no matter what some in-universe-source says.
That aside: Consider the nature of the holocron. It contains recordings made by Jedi. And there you have the very problem: When Kun constructed the blade, the former Jedi trainees and Jedi (he recruited on Ossus) were under the control of the spirits from the stolen Sith holocron. The only "normal" people left were Ulic and Aleema - who spent their time away from Yavin 4, so they wouldn't have noticed what Kun was doing - not to mention that Aleema was killed before the end of the war. Yet Kun's knowledge perished together with the Sith Lord. So please tell me how the Jedi could have obtained any details about Kun's weapon design. From Lala-Land?
Then we have Kun himself who asks Vodo if his former master likes the "modifications" he has make to his lightsaber. If he just modified his own weapon, that rules out the possibility that he constructed an entirely new one. That he has gotten the complete design from any obscure Sith holocron is ruled out too - ironically by JvsS as source itself which claims that the Jedi Exiles becoming Sith Lords have "abandoned the use of lightsabers" which, 3000 years before Kun, where still those nice constructs with cables attached to them, meaning that any Sith Lord in the starting days of the Sith Empire coming up with the design Kun was using, would have had to made a quantum leap in lightsaber design to even consider such a construction possible [as the Jedi were still using the cable-design 2000 years after that this is rather unlikely].
Yet even if we assume that this idea of an in-universe-source is correct. How does that affect anything said about Exar Kun? Even if he discovered the design idea in some Sith holocron, constructed the regular-length hilt DBL from some blueprints he found and used a corresponding style he also found within said holocron - all of that would have been wiped out together with the Sith Lord himself. Unless you want to tell me that the Jedi that saw Exar Kun fighting with Vodo did an in-depth-analysis of his weapon and the corresponding combat style in the matter of minutes.
Which means that neither Dooku nor Mace would have the slightest idea about Kun's style or weapon. And then one could ask the question if it's harder to confront an opponent that uses an unfamiliar style [Kun facing Dooku or Mace] or if it's harder for one of the duo to face Kun - the guy who uses an unfamiliar style, an unfamiliar weapon, alters blade-length and intensity of his blades in combat aside from being more powerful and knowledgeable force wise than the two PT era force users.
To me the answer is pretty clear. But of course you can keep on with playing dumb and tossing out your Kindergarten level insults instead of putting any effort into an actual debating. Which might, of course, be healther for you, since we all know that trolling is your business and your attempts to construct arguments are even more pitiful than your attempts to be funny.
