There are two distinct sections on this climb: The first bit is superb jug hauling starting with a slight traverse (.10d).
To complete the .12a, don't clip the anchor bolts under the roof, instead clip the lead bolt to the right or the anchor and continue up. You get a no hands rest at the roof. Then the business starts; it's an overhanging, crimpy problem to some better holds up higher. The climb has some cool vertical fins, not unlike shark fins.
This starts right of Litmus Test, i.e., the second bolted line right of the tree on the north side of Division.
10 bolts to chains. You'll need 12 draws.
