I'm working on my Tyrian exploration title and I need a whole lot of the bonus area, especially away form the main fort. I decided to try a hench group, as I remember at 2 mins to go the monsters stop coming. I was paying attention to the gates to the outside as I went to kill the enemy ghostly hero. I noticed that a few seconds after I attacked, not killed, the hero, that the gates opened. I immediately rushed back, hoping the monsters would not come so I can explore at my leisure. But the mosters started to come as usual so I rushed back and killed the hero. Afterwards, I thought about what had happened. What happens if you don't kill the enemy hero after 10 mins is over? Do you lose the mission (which I think happens

), or do you get to keep going until the hero dies?
Please help, and don't tell me things like; change to necromancer (im warrior/ranger at the moment, almost never, ever change (I'm working on a warrior/ranger hammer troll farming build so I never, ever have to change at all

)), and get necrotic traversal or whatever.
