[Okay, meta-game question: Fendric has a Lesser Restoration prepared - can he cast it to positive effect even if he doesn't know what attribute loss Nurthk is suffering from? In other words, would the Lesser Restoration restore points to the right attribute on its own, or would I have to guess?]
Fendric looks at Furgus: "The nearest cleric of sufficient ability to cure Nurthk that I know about is back in Bethel; anywhere else, like the city on the coast, we'd be taking a chance, and then there's the matter of getting him there alive, may Pelor grant us aid in the journey. Today, I wish to attempt a Lesser Restoration, and tomorrow, when I can prepare the spell, I will attempt to Cure his Paralysis, which if everything goes correctly, may the Radiant Light make it so, should allow him to take food and drink."
Fendric then looks up at the rest of the party: "I think our best recourse is to take that chance, and head downriver to the coast. For that, we shall need boats, and at least one of sufficient size to carry our friend lying down throughout the journey. Will one of you fetch Ozzy, and see if we can borrow some?"
Finally, Fendric looks at Shavah: "It would appear that our choice is made for us, and that we shall have to abandon Father Premule for the time being, as I will NOT let Nurthk perish if I have the power to help it. May Pelor forgive me."
