Running - 8d6 → [4,1,5,1,6,6,6,2] = (4 Hits)
Climbing - 10d6 → [1,4,1,4,2,3,1,5,3,3] = (1 Hit) *
Infiltration - 12d6 → [6,6,2,1,5,3,5,4,6,1,3,5] = (6 Hits)
So I make it upstairs handily, and I not only maintain my stealthiness, but become even more ghostly.
Unfortunately, I flubbed the climbing roll and assume I either make no progress, or at best only a fraction. Fortunately I didn't glitch, so I'm safe and sound. I'm picturing Nick focusing so hard on not being seen that he misjudges the second handhold and has to cling one-handed for a moment, dangling in a shadow below the roof edge, getting his bearings before trying again.
* The Climbing test I was a bit unsure on, specifically the difficulty modifier for the climbing surface. Looking at the table on SR4A p. 132, and considering the nature of the climb based on the image of the building, I was waffling on what would be appropriate. I ended up going with a "Broken" surface modifier of +0, both because it seemed appropriate given the "handholds" available based on the picture, and because a neutral modifier stays in line with Arcana's prior posted test requirements.
If needed I'll reroll with a greater (or possibly lesser, I guess?) negative difficulty modifier, but since I'm gonna have to roll again to get anywhere anyway, it seems like it hardly matters.
