Hmmmm.... Drop something really really really heavy on someone? Like Mara's tactical nuclear ballistic iron golem strike?
Too many spells there. Hmm.. Maybe something really big? Like a whole building? But made out of something really dense, and really heavy. Like instead of stone, adamantine or something... Yeah! A whole building built of adamantine..... But not some little house or something.. I want like a 30 ft tall, 3 story TOWER of adamantine to drop on someone...
But how do you get one of those that you can carry around with you without being in a cartoon?
Yeah, yeah, you get where this is going. There just happens to be a 30 ft tall, pure adamantine tower in the DMG that shrinks down to pocket size to carry around with you and only takes (you guessed it) one round to form.
So let's see... We have to approximate the weight of the thing.. The nearest thing I can think of to something 30 ft tall and heavy and dense as a 30' adamantine tower is a 32' tall huge earth elemental. They weigh 48,000 lbs according to MM pg 83. Now this is a 10x5 creature of stone, not a 20x20 tower of adamantine, that's only an 8th the size.. So if we know it's the size of about 8 huge earth elementals then 8 x 48k = 384k. But this things got a lot of air inside it too (walls, supports, furniture, and everything else not withstanding) so let's keep the math simple and round it down to 300,000 lbs.
Now then, if we drop this thing from atop a 50 ft cliff, that should give it precisely enough time to grow before it lands while still occurring in the one round time frame required for a smackdown... According to DMG pg 89 a three-hundred thousand pound object that falls 10 ft does 1500d6 damage.. Plus a little more for falling 50 ft. instead of 10 ft (not much more, it's the weight here that makes the difference, not the speed so much, though both weigh heavily...ack, sorry..
)... Times average damage of a d6, comes out to around... 5264 damage. That just manages to beat the smackdown 200 damage minimum. 20 ft diameter impact, reflex for half if you are feeling mean, reflex negates if your PC's enjoy a little adrenaline fix from russian roulette. 
Of course, a Daern's Instant Fortress will cost the first level PC who's dropping it around 55,000 gp, so there might be a few financial problems, but who's counting?
