The basic idea is: When a player casts dark swarm, player 12 will command a dark swarm. Center a location on the dark swarm, and remove
the dark swarm. Then kill/do whatever to units at the location and create explosion effects if desired.
With multiple players, there are 'shot conflict' problems... For a detailed description, check out the tutorial:
http://www.staredit.net/index.php?tutorial=41You can't do the same thing with stasis field, because stasis field isn't a unit and you can't center a location on it.
The only other spell which you can treat in a similar way to dark swarm is disruption web.

Edit in red to remove ambiguity present in pronoun use. Don't want any ideas that you can remove a Location.
