On soulweaver im gaining soul sparks for doing nothing all the time, even out of combat. Using dreadtheft has a good chance to lock your character looking backwards and not even killing yourself fixes it, you have to relog. The first feat on the bottom in soul weaver makes your tab not deal damage.
Im a little late since this was talked about last night but regarding the soul puppet immediately dying when being spawned, this only happens for hellbringer fury from what ive found. It works fine in Soulbinder fury, and Hellbringer temptation.
