Monster's attacking range?

I only really attack the 2 middle layers in the direction that could make them fire off that attack (well, since I use Ice, I only see it if I get some angry and don't kill them, like if I cast HH at the top and then drop down) - so personally I'd probably stick it on the rope up from the ground floor in the bottom right corner. I always do the bottom one right to left, so there shouldn't be as much risk.


I think monsters lose aggro when you go onto platforms below them so it's possible leaving it up at the top platforms could be safe.
