Beyghor Sahdett as a swordsman was well known in the Jedi Order.

Kai Hudorra : You know he is lying don't you Jennir?

Dass Jennir : Yes. I've known for some time. But I also know his reputation with a lightsaber. I knew I couldn't take him myself. That's why I needed your assistance.

Sahdett was a skilled swordsman, not top tier like Maul or Vader, but he was was certainly above the average.

I like this. Sahdett is really very powerful, as Dass Jennir was around Kai Hudorra level, who gave Vader a good fight and wounded him. And Sahdett drove them both back, and held his own. He's low-key underrated.
