Currently, Power Cogs use Kinetic Field's end sound upon getting destroyed. This same sound is also used by Magnus' Shockwave upon hitting enemies. So it is used 3 times.

Power Cogs could make use of a unique sound, instead of sharing it with 2 other spells. Since they are mechanical things, it's easier to get a fitting sound for them.

Here are 3 examples (right-click the player and "save audio as" to download):

* sound 1
* sound 2
* sound 3
