What classification of spell is imprisonment? I can't look it up in my spell slot cuz I haven't learned it yet. And where could I find a freedom scroll. I know about the ones the duergar sell when you get to the Underdark but I'm no longer there.

Also, how would a fighter type protect against it? There's a certain lich that shoots it off like a machine gun and I hope Spell Immunity will protect my mages once I find out the classification. But what would a fighter or cleric do? Thanks.
