Nikolos will, of course, collect as many intact crystal books as he can manage, even if he has to climb up on the stacks to get them. He'll put them in his pack, as securely as he can manage, before resting, making sure that Caramip has a reasonably comfortable place to sleep, as well as Danica, before taking his own rest. In the morning, he will pray to the Seeker, for guidance and strength, and make a number of changes to the divine powers he asks for.
After his prayers, he will go to Caramip, and offer her a small platinum ring. "Honor me by wearing this today, if you would, and remain as close to me as events permit."
Afterwards, uncharacteristically, he'll lead the way down, sunrod advanced. Once they reach the trapped room, he will cast comprehend languages, touch one of the books, and then walk over to a point just short of the edge of the trapped area. There, he will cast read magic, and see if the two magics combined can let him decipher what exactly it is they are dealing with, hoping that the writing on the tiles is at least based on the same language as the books contain.

Changes to spell selection are on the revised sheet. I might be pushing comprehend languages a bit, but it seemed worth a shot.
