Cue the Confetti

Stand start with a left hand on the arete and a right hand on an undercling. From there, achieve a high right foot edge, reach a left hand edge up high, then traverse right through an edge, reach the shelf/massive sidepull, then go straight up, and mantle atop the boulder.

It climbs the west face slab of Megalomania.

A pair of pads will work, the landing is perfect.
