Walk over to the room with the Monk, as him this:
"Hey, I'd like to ask you something. Can you tell me more about the gods these shrines are dedicated to? Gotta make sure to not cause accidental smiting of myself."
There are eight in total: Yo-drell of the Deep, Sha-calun the Everflame, Flux, Parathun the Fleshsmith, Scarlon the Mask, Blastel and Nul-sheal the Green. The Mark of Flux is upon you. What information do you seek?
"Now, I don't mean to interupt, but that's only seven names, no? Anchor of the eight, eight rooms below, eight gods... Who's the last bloke?" Glassco asked after a few moments to ponder on what he heard previous. He waited a moment to see what the response would be, but then he got an annoyed look on his face slightly later, just now realizing how long he's been talking, and sighed. "Sorry chaps, 'fraid I better be heading off soon, gotta make sure my new found friend isn't getting himself in trouble and all that, you know." Glassco gave a crooked smile, giving a bow to the monk, "thank you for all ya words and help," and a nod to the newcomer, then heading downstairs to try and find his new ally.
If found:
"Holy shit, what happened to you?! Hold on, hold on, I think I got something that may help... Hopefully. Glassco says words while running his hand along the opening of the wound, or rather what was left of his arm.
If not found:
"Hm... Where did he get off to?"
Glassco makes a final comment to monk-lich, waits shortly to see if response, then tries to find friend. If found, words. [The words being contingent on if he doesn't get the bleeding stopped on his own, that is.]
