(OOC: Ah, okay, so you wanted to climb the entire ramp and get all the way to the tunnel mouth while the Afflicted were still all the way down the other end of the tunnel. That is unfortunately not feasible based on the distance of the Afflicted before you noticed them. Assuming a sprint up the ramp, you could be anywhere from 0 to 80 feet up to begin--Hulgyr can be substantially farther but isn't because you're holding formation. I assume you prefer the maximum. That puts you right at the landing near the tunnel mouth after you advance 20 feet)
