Reworking  Xilimyth 's Sith weapons.
She's now sporting a pair of gauntlet mounted wristblades. These help her focus on lunging and high impact attacks. The twin blades of each saber resonate to make the sabers more durrable, which is neccisary, given her natural physical strength, and lets her be a bit more reckless w/ her attacks. She'd need to move more of her body, than one would w/ a normal blade, with each attack, but that alows her to combine her speed, strength, and weight behind each strike. (Yeah, she'd Pimp-Slap a defensive saberist like me, across the room) Also, the way the sabers run across the length of her forearm helps her deflect melee attacks with minimal effort.
However, as wristblades, they don't have length or range of motion, of a normal lightsaber- so she can't use Form 2, or Form 3 saber styles very well. (i.e. Finesse or Defense, respectively)
To make up for the gaps in defense, (and add some extra intimidation) Xili has a pair of mini-probe droids, mounted w/ spinning inquisitor sabers. They're mostly A.I. controlled, providing cover, without Xili needing to focus on them too much, but she can easily move them telekinetically, whenever needed.
(I'm tempted to put energy shield projectors on her gauntlets too, to deal with blaster fire)
I imagine she'd use a cross between Yoda's Form 4 and Vader's Form 5: combining the unnatural speed of Form 4, with Vader's ability to use physical strength and intimidation to control the duel.

(yush i put too much thought into this)
