This is a Pure Class Stamina Sorcerer Non-Pet build for Update 49/50.
I've included a Parsing setup I would intend to try out in u50 PTS and a content-ready setup.
The goal will be to get implosion to fire off frequently, so we are stacking multiple per-second attacks, such as bound armaments and rapid strikes. Unfortunately, this build does not have a lot of AOE damage effects, so the content setup uses traveling knife, which still fires off multiple times per cast, which should help with the AOE slightly.
