Stone Call with Dazing Spell metamagic feat. Takes a 5th level slot. No SR. No save on the damage, but foes would get will against the 2 round daze effect.
I would try to find a no-SR spell that uses a reflex save (save for half, partial, or negates, doesn't matter) and apply dazing spell to that; many foes are weak on reflex save cause...seriously, who cares about reflex save?
