I was just keying the climactic battle of my next stage (against a Half-Fiend Fire Giant) when I looked up Blasphemy and saw its effects. Okay, based on that, anything up to Level 10 is paralyzed for 1d10 minutes with no save, which is effectively the same as instant death. As my party is at Level 10, that makes the battle unwinnable because they have no reason to prepare special defenses against this spell.
Is a saving throw justified, perhaps?
