Having reached the base of the falls, he pauses to think.

Wet. Cold. Loud. That sounds like the past two weeks of my life.
Still, maybe...

Still pensive, he steps slowly towards the base of the falls. His eyes scan the darkness for any sign--or even any likely location for the Lizardman's location, including debris from the boats or dropped gear. Heavy footfalls carry him close enough for the sound to drown everything out, for the spray to soak him to the bone. To try and experience exactly what Yix described.

"GET UP! GET UP YOU BASTARD! I am not going to spend all night swimming the Styx to find you!"

His voice grows hoarse as he shouts in Draconic, but his mind remains focused.
