The 8th stage of the annual John Van Caneghem Tournament (2007).

Support hero Lord Haart (the one who is alive), he has expert diplomacy at level 5.

Yes, I didn't find any diplomats earlier... :( Mine were at level six and seven - I had to simply wander around the respawn for leveling up, a lot of time was wasted... Alright, decision made, I need to improve scouting... :)
