The start is from the block with Krokus' top anchors, and a belayer should probably be clipped into these anchors to avoid falling to the bottom of the south side (50+ feet) in the event that the first bolt on the route blows.
This slab climb has an interesting beginning move to get from a large flake onto a slab that has literally no holds on it. Getting from the first to the second bolt is terrifying, and run out. A fall in this area will send you tumbling over the roof, which would not be fun.
The crux seemed to be from above the first bolt to 4 feet shy of the top anchor.
If you don't trust your feet, don't do this climb!
This is rather a very awkward route for me! If you are only pulling plastics in the gym, you will find this route very difficult as this requires a lot of balancy and interesting moves that you do not encounter in the gym. I put a longer sling to the 2nd bolt to avoid the potential groundfall.
