Black Hole

When you cast this spell a mini-Black Hole will appear causing everyone (including the caster) within 500 feet of it to make a DC 25 strength check or be sucked into the Black Hole. On a failed save take 500 force damage and be sucked into the Black Hole. On a successful save take half as much and don't get sucked into the Black Hole. When a creature gets sucked into the Black Hole it gets bigger and lasting an additional round per creature sucked in. Items that are not being carried and are not held down by anything will also get sucked into the Black Hole. Anything sucked into the Black Hole is lost forever.
