Okay, how do I get to fight the Taskmaster? I've defeated the traitor Mander and put the sleep poison into the guards food. I follow the arrow to where it tells me to go and there is nothing there. I've fought and beaten that Mander 4 times. I've poisoned the food over 10 times, I've equiped the magnetic wand you get off the traitor mander and nothing is working. I was expecting a battle to happen, but there is nothing there.
DO NOT kill champion before you do this quest! I had 2 quest kill champion and kill taskmaster I was closer to champion so I killed him first as soon as I did the quest log for killing the taskmaster vanished from my book. I went ahead and killed taskmaster but nothing happened. I already reported this bug to Kings Isle.
