Wall of Force can be cast as a dome. If I choose to trap an opponent in this way, is there a saving throw?
The spell description does not list one.. So I know there isn't one RAW; But I'd like to know what the popular wisdom is.
There is no save. Worst case, trapping an enemy this way basically removes that opponent from the fight until you lose concentration or the spell expires. I have used this as a player as a way to get away from a very strong opponent, 10 minutes is a long time to run flat out, and the spell does not specify that it is dispelled if you move too far away.
Also, I allow this as a DM. I am fairly certain this is an intent of the spell design.
