Crux is matching up on the two underclings and making a powerful move out left to a crimp. I have fussed with a little bit of beta on this route and found that just high stepping with my right foot to the point on the feature in the cave is probably the best option for getting up as high as possible on the left hand undercling before falling in with the right. Powerful!
Location
Route begins as for Against Humanity. Low down in the cave on an undercling.
