Getting me nowhere, but gain support from almost everybody here, bar yourself and Gideon(one guess why that is).
Firstly you're contradicting yourself and sources, how can Kun harness unlimited power because he isn't mortal, and be somehow more powerful due to this via Kyp Durron despite Kun requiring his 'lost reserves of energy'(JA Sourcebook) to resurrect himself in human form, which would be accomplished by 'draining Luke and the other trainees'(JvsS).
I.E. Kyp, Gantoris and Streen combined weren't capable of restoring those energies, he required Luke's energy and the energy of his dozen students to achieve his intended resurrection, which is accomplished by regaining his lost reserves of energy.
So... he is somehow beyond his capabilities as a mortal, but lacks the power he needs to resurrect, which is accomplished by regaining his lost reserves of energy? There's a break in logic here and it sure as hell isn't on my end.
I have provided proof that for him to return, which is what he'd been trying to accomplish the entire trilogy, he would have to restore the Force energy reserves he had when he was alive. Which Kyp wasn't enough for, you know when Tom Veitch confirms he was at his most powerful, living.
I mean you use the statement 'the full might of Kyp Durron' as if it's a settlement on the issue, when it clearly isn't Beni, learned nothing have you?
Kyp Durron was being amplified by Exar Kun's power, which made his own power focused by a temple, comparatively feeble:
He reached out with his mind, following the paths of the Force that led to every object in the universe, drawing power from the cosmic focal point of the Massassi temple. He searched, sending his thoughts like a probe deep into the storm systems of the gas giant. Behind him, Kyp felt the black-ice power of Exar Kun arise, tapping into him and reinforcing his abilities. His own feeble exploratory touch suddenly plunged forward like a blaster bolt.

The 'full might of Kyp Durron', is feeble, frail, and delicate, compared to the power afforded him by Exar Kun.
As Corran Horn states, Exar Kun was exhausted by the effort, not Kyp Durron.
Infact, Exar Kun's supposed limitless capacity, isn't very limitless whatsoever:
Kun finds Gantoris, strong-willed and impatient to learn, to be a more promising first candidate. He easily seduces Gantoris in the same manner that Nadd had seduced him—by promising forbidden knowledge and the truly powerful Jedi secrets Gantoris cannot wait to learn. Carefully building up and feeding on the anger of his first apprentice, Kun grows in power. Soon he feels confident to make an attempt to subvert Luke, knowing that if he can sway the teacher, the students will all follow. Kun, posing as Anakin Skywalker, appears to Luke and attempts to pull him toward the forbidden Sith teachings by tempting hi to use Sith power to seize control of the New Republic and destroy the Empire. Realizing that this shade is not that of his father, Luke rejects the offer.
Enraged and drained, Kun returns to Gantoris. Desperate for more energy, he goads Gantoris to new heights of anger by showing him the Eol Sha colonists dying on Dantooine. Gantoris is pushed too far, however, and turns on his Sith master. Realizing that Gantoris is no longer his, Kun utterly drains him to provide himself a reserve of energy to last until he can subvert more students.

So any attempt to influence the physical realm exhausts his energies almost instantly, he is never this limitless spirit that can weild unlimited energy. He is a Sith spirit and can return to physical form by regaining his lost reserves of energy.
Those lost reserves of energy not being somehow increased by the ritual either, the energy fueled the ritual and allowed him to become a spirit, he was going to 'run rampant' across the cosmos but Nomi sensed what he was attempting, the ensuing Wall of Light trapped him in the temples, which he used to survive and maintain his will without being dragged into the void.
I find it humorous at best, that you claim to have debunked anything, when it simply appears that you're ignoring statements and speculating as to why you're correct.
You point to Exar Kun shedding his chains and mortal coil, but ignore that it immediately follows with his ability to traverse the cosmos. As in he can move around the galaxy without mortal restraints. When it states he became one with the dark side, it means he died and became one with the Dark Side, not achieved some unlimited power.
If you have any actual substantial proof going against the already confirmed power levels of Kun's spirit, aid or no, and how it relates to Kun's powers as a living Sith Lord, which I've provided repeatedly, then state them.
On the duel with Ulic, unless you have actual evidence that they were using Force powers, rather than what is stated to be a pure contest of swordsmanship, provide it. More speculation won't get you anywhere, Kun is famous for his need to prove himself against his peers, something he did here.
Regarding your hilarious misinterpretation of my alchemic statement, it isn't that alchemy made Exar Kun more powerful, it is that he'd grown extremely powerful by the time he had resumed his alchemical practices on Yavin IV, which is exactly what happens in the story.
Kun starts practicing alchemy, creating the Massassi Abominations and the construction of a large network of temples, finishing Naga Sadow's incomllete works. But Kun decides to take the Corsair to deal with Ulic and Aleema, they join forces, Kun goes to Ossus and kills Odan-Urr, he takes in it's knowledge and becomes more powerful. He then converts the Jedi students by unleashing the spirits in the holocron whilst on Yavin IV, thus starts the assassination attempts on the Jedi Masters, Kun rescues Ulic from Coruscant. Kun then returns to Yavin IV and resumes his alchemical creations.
Comprende esse?
Seriously, unless you have something beyond your own speculation on cherry-picked information, then this isn't going to go anywhere. You're proving nothing whilst I provide statements supporting exactly what I've stated.
