i think they need to incorperate maphack into JED for a mephbot script to work. the reason for this is cause the spot for durance lvl 3 staircase is different every single time.
with pindle the portal is in the same place every time. so it just goes to a specified coordinate.
as far as i know maphack is not a part of JED yet. so i dont think they can even make mephbots for it yet. i know ive heard them talking about doing this though sometime in the near future.
just run the pindlebot. meph cant drop certain items anyhow. pindle can drop anything in the game.
