Description: Zothan Venn developed an unhealthy fascination with power tools when she and her twin were tramping about the galaxy as thieves. When she first discovered a chainsaw, she was simply in love. Since then, she has become obsessed with unconventional melee combat.... So she took the insides of a chainsaw, a chain and rounded slab of turadium, and a bunch of blaster battery packs. It's pretty resistant to most other blades, and Zothan's heightened reflexes can make her move fast enough to actually block blaster shots, but only rarely.
The downside, of course, is apparrent. It's just a large, heavy spinning blade. It's reach is large, but nobody but Zothan would ever use something as truly insane as a gigantic chainsaw as a weapon. Besides this, Zothan would never think to use the saw as anything other than a blade. She could probably throw it like a lightsaber if she wanted to, but she avoids ranged combat except at her most desparate moments.
