Re: Trapped in the Underdark ~ Out of Character discussion
Clerics version is Commune, which get's yes or no questions, or at most a few word short sentence. The next closest is Divination which can get you a short sentence and advice on a subject like "Should I put the mask on."
Clerical divinations are pretty imprecise for that reason. But they have an inherent advantage over the wizards direct methods. Because they are indirect, defenses against divination spells like mindblank don't really help at all, since you're not trying to affect them, you're asking an supremely powerful other person questions. This allows one to track down Mindblanked individuals, albeit very very slowly.
Contact Other Plane also comes with a barrel of risks as well since the odds of burning out your brain are not small. And it's still not guaranteed to work as the contacted critter can lie or not know.
I'd do Analyze Dweomer/Legend Lore first before jumping to the nuclear option frankly.
