Just left of Necrophelia, climb flake/crack past scary rocker block. (I attempted to trundle this block, but it seems to be stuck in place. very scary if you grab it and it shifts on lead though, beware.) Once above the rocker, step left to nice face past bolt. Keep reaching left until you find thin crack. Then thin cracks lead to the top.
center of Necro Wall
standard rack, one bolt.
