Oh. I was expecting it to LAUNCH a sawblade, akin to the radar disc of Zenith.
So it's supposed to be a nearly worthless weapon? Why would anyone use alternate fire or waste a potato if it's nothing but mastery fodder?
"Alternate Fire launches a floating sawblade, dealing continuous Slash Damage"
When I use Alternate Fire I see no floating sawblade, just a beam coming out of the barrel that appears to do no damage at all.
