OK, so I'm trying to figure out how to do this. I want to make a teleport that will go wherever you point it, but will stop in front of, rather than on top of, a blocker, monster, or anything else that would normally stop a missile. The problem is that type="beam" and type="beammissile" both go straight over blockers (which you'd think a beammissile really wouldn't), and type="missile" stops ON the blocker or monster, not in front of it. Is there a method to accomplish this goal, or am I barking up a nonexistent tree?
Maybe by triggering a type="template" (30 or 629 probably) teleport on arrival, but the problem is to determine if the missile was blocked and choose the direction to go "back" instead of the default north. Edit: With a little luck, anchored="1" remember the direction the player was facing when casting the spell who trigger the template.
