This route climbs the left-leaning cracks on the south-east side of Cannibal Crag. Start in the left-most crack, merge with the second crack and shoot for the top of the boulder. Alternatively, you can traverse left near the top to the cold shuts on Caliban.
Definitely harder than, 5.4. I would say 5.6. I am new to trad, and so far have found every route rated 5.4-5.5 (in Red Rocks) sandbagged. I felt they were all harder.
I did this route as my first route in Red Rock as a solo (after soloing regularly in the Peak District in England) when I first moved to Las Vegas in 1997...the top out is the crux. I remember standing there for about 15 minutes...wondering if I would make it. My last solo!
