Kas'im respect thread
Kas'im was the twi'lek blademaster in the brotherhood of darkness. He trained many of the sith in the art of lightsaber combat including Darth Bane himself. I issue a SPOILER WARNING for Path of Destruction if you haven't read that book yet (Really?).
Force Powers
Kas'im blasted open a heavy door with a force blast.
Recognizing what was happening, Kas'im blew open the heavy door of the side room with the Force and dived inside. Page 292 POD
He was unaffected by a force wave strong enough to crumble a temple
The concussive blast had enough power to shatter every bone in Kas'im's body and pulverize his flesh into a mass of pulpy liquid. But at the last possible instant he threw up a shield to protect himself from the attack. Page 294 POD
Lightsaber accolades
Kas'im's form and technique were flawless. Page 191 POD
Kas'im had trained his entire life for this moment. After years of study, he'd mastered all seven forms of the lightsaber. Then he'd honed his skill for decades, perfecting every move and sequence untill he had become the perfect weapon and the greatest living swordsman in the galaxy. Maybe the greatest swordsman ever. Bane was no match for him. Page 293 POD
Lightsaber feats
He appeared to be wielding six blades rather than two while using two blades.
The Blademaster was unrelenting in his preasure. He seemed to wield six blades rather than two: Page 293 POD
Kas'im struck over six times within the span of two heartbeats while using a saber staff.
Kas'im lunged in again, and the room was filled with the hiss and hum of lightsabers striking each other half a dozen times within the space of two heartbeats . Page 291 POD
Anyways those are all the feats and accolades I found that were worth mention. There aren't that many of them but they are impressive.
