I had to reread the chapter to really understand how they work...

Correct me if I'm wrong....

You pull a trigger which fires a gas (like what ODMG uses) rocket that propels the entire spear forward guided by the position of the arm.

Simultaneously, you should be moving perpendicular to your target (in contrast to directly towards your target like with a sword attack) so that you quickly clear the blast area.

Then, you still have a string connected to your arm which is also connected to the back end of the spear after the spear rockets into your target, you have to either yank your arm or put some distance to pull the string which appears to activate some sort of triggering mechanism when the string is pulled out.

Here's what I'm unsure about...

Through some sort of process that hasn't been explained yet, the spear, which is described by Hange on Page 28 as 'like a bolt of thunder' which might be a mistranslation since she may be referring to lightning and not thunder, the spear apparently emits electric arcs and then explodes. Which makes this novel for world within the walls technology because so far it's the only depiction of any kind of technological utilization of electrical forces.
