You led a pig from Majula all the way through the misty forest, past the invisible annoying things, through doors of pharros, past the other pigs, all the way to the bottom of tseldora? Damn, son.
This was easier than I thought it would be. Just clear the path best you can up until the zipline (use bow/crossbow for the warlocks too). Then back track and follow the instructions. The pig will miraculously make the jumps. Carry a torch if you have trouble with the spiders.
