Or you could do this *holds out left hand, circle with symbols appear around feet, bows head for a moment then raises it while eyes glow, a circle similar to the one at my feet appears in front of my hand and from it an arm made of shadows grabs the ghost spirit and drags it into the circle, the spell ends and the circles fade as well as the glow* there problem solved!
"WTF WAS THAT!"" *they turn around and see a goat ghost*
