IcyCool said:Fifth level spells? Not many. Plenty of lower level spells though. Most of them have already been mentioned ...
Okay, I should have said "5th level or lower."
Spells mentioned here do not help everyone trapped, or simply don't work. Someone mentioned fly, that doesn't help you if you are trapped. Dimension door helps you if you are trapped, but it doesn't do much for your fighter friend who spends the next five rounds trying to make a DC 25 strength check so he can move 5' through the thorns. Freedom of movement helps, but only one person. A combination of FoM and DimDoor or multiple DimDoors might do the trick.
Dispel magic helps of course because that works against nearly anything.
