The mental crux of this climb is reaching the first bolt. A slabby start with small holds leads up and right for several meters to that point, from which you traverse right to access a good crack. Climb that crack to the top of the rock on good locks and good pro.
This route in on the North Face of Tom's Thumb. It is found by going just left of a right-facing dihedral that turns into a right-leaning roof 6 meters up (this is the climb 'Sucubus' a 5.10a). The crack that is accessed via face climbing is continuous with the initial start of Sucubus were you to skip the roof to the right.
A set of nuts a few smaller cams and some slings. A bolt down low is good protection just as the distance from the dirt would be too dangerous.

Found the climbing to the first bolt to be easy and there are a couple good placements to protect. Crux for me was exiting the alcove (with an amazing 2-foot mound of guano in it) by stemming and getting up into the thin crack above. The mental crux was the extreme runout between thin gear for the top 50 odd feet or so. A couple bolts would help (I think the hanger from the original is now gone)!

Starting on Succubus into this must be the non-direct?

Exiting the alcove/cave in the middle is the crux and feels insecure. The run out at the top is on easy ground. Small offset nuts were useful at the start.
