difficulties range from 5.7 to 5.13. 5.7 is actually quite easy while 5.13 is extremely difficult.

from nps.gov:

Hundreds of parallel cracks divide Devils Tower into large hexagonal columns, making it one of the finest traditional crack climbing areas in North America. The longest of these continuous cracks are almost 400 feet long and vary significantly in width. Technical difficulties range from 5.7 to 5.13.
