Can You Kill a Glillyscent Fromkin?

"I just have to see what the inside of this cave is like," says Boergard. "We should go around the side, set up the dome, and then send in fromkin, yes? Set up the dome?" he asks Rini. "Can you press the dome twice and one day?" 'Yes,' she replies. "'As long as I sleep' It's a third level spell, so it can be cast multiple times a day." The team decides to head into the cave together because they're better as a team.
