Will Bosi has made the first ascent of Realm or Tor’ment and suggested V17 for the grade. The eight-move power line is found in the Peak District, U.K.

This is Bosi’s fifth V17. In October 2022, he climbed his first of the grade, making the third ascent of Shawn Raboutou’s Alphane. Less than six months later, he bagged his second V17 with his second ascent of Nalle Hukkataival’s Burden of Dreams. In February last year, he made the second ascent of Daniel Woods’ Return of the Sleepwalker in Red Rock, Nevada.

In October 2024, he surprised many with a rapid second ascent of Aidan Roberts’ Spots of Time. In February this year, he made the second ascent of Stefano Ghisolfi’s Excalibur. With the ascent, he joined Jakob Schubert and Sean Bailey in the very small group of climbers who have climbed both 5.15c and V17.
