RJS has achieved the achievement curbstomped, for one-shotting a human or vampire (In this case, a vampire)
For this, he finds nearby a strange, cylindrical object. Upon further inspection, he finds that it has a switch on its side, and has an energy cell loaded in it, only partially charged. The clever lad nearly stabbed himself in the eye, earning him a few singed hairs. The sod found a lightsaber.
The lightsaber has about a minute of charge, half an energy cell's worth of power, but is extremely damaging. GG!
