Start sitting with hands matched on low large jugs at 2.5 feet as for 'Fatal Flaw'. Use an assortment of underclings and crimps to traverse right to a large sloping rail feature. Follow this rightwards to its end to get stood up on the slab. From here, mantle onto the sloper rail to gain a good stance. Top out above and slightly left with a tricky mantle on sloping holds.
A fun line that is arguably less contrived than 'Fatal Flaw', though still contrived in its own right as you could move left into 'Endo/Endoscopy' at multiple points at the start and you could bail left into the 'Endo' top out for the finish. That being said, the line makes sense logically and climbs pretty naturally. A nice option if you're struggling with the upper part of 'Fatal Flaw' and/or you're scared of the mantle on that line.
This climb starts near the left side of the 'Left End Proper' main wall. It starts the same as 'Fatal Flaw' and 'Endoscopy'. It is the blue line in the topo photo.
A few pads are helpful since the climb traverses a lot of ground.
