Malicious Sorcery
Scepter autoattacks are weird. It’s pretty much a melee weapon. The next bolt won’t fire until the previous one hits, so being right in your target’s face is much faster than max range. Try using skill 3, it goes much quicker. Or go mining or chopping, the animations are definitely sped up. At least you still get the condition damage boost. There’s a reason it can get away with having that 30% attack speed trait and not be OP. Attack speed doesn’t really affect it.
