Changes

When fueled by a certain amount of demon blood, Sam powers are strong enough to allow him to not only [[exorcise]] [[demon]]s, but kill them too. Killing a demon creates the same light inside their body as when they're killed by [[the Colt]] or [[Ruby's knife]]. When killing [[Alastair]], Sam was able to do so with ease, but [[Lilith]] required extreme concentration and will, the result of which drained him of all his powers upon completion. After consuming several gallons of demon blood in preparation for becoming Lucifer's vessel, Sam was powerful enough to kill two demons without moving a muscle. Sam is also capable of inflicting intense pain on any demon, which proves useful in torturing them for information for the agony is so great that Lilith's servant begged for death after just a few minutes of exposure. However, after her resurrection, Lilith insisted that Sam was only able to kill her because she allowed him to.
