This might not be the best Route but its the one I used and it sure does work.

Intructions starting from phosphorus (15) follow the black and colored lines to show the way. It starts going to the left with a red arrow. In the top left of the image there is a key, red is electrocute so that is the first step, follow the colors and the paths until youv'e finished. There might be some spots that are harder to understand, message me on discord if you need any help.

If there's anything wrong with it or you've found a better method/route publish it for everyone else to see :)
