Those words sounded too ominous, but in the end, Luke wouldn't let anything surprise him. Before leaving the house, Luke checked the garage for some nails, and he found a box of those. While five Spark Balls did the trick in killing the red fangs, Luke couldn't forget Weapon Augmentation. It was pretty hard to make the skills reach level four, so they never will level up unless he trains them regularly. Besides, Weapon Augmentation was a lot more silent when used alongside small projectiles. At the same time, Spark Ball made those noises of high voltage.
