Stage 5 of the John Van Caneghem Tournament

Thanks... I was generally trying to complete it on difficulty 11, but I made a couple of mistakes:
1. I forgot to take the Boots of Swiftness at the beginning, I took them too late.
2. I forgot that you can install the Grail on level 15 of the city.
...

On what day did you get the Boots of Swiftness, and when did you dig up the Tear? P.S. I personally enjoyed the battle with the Death Messengers and Banshees (more than 50 of them) with a hero who seemed to be level 10. The main troops seemed to be around 50 Ogres and 12 Shamans, plus Goblins. Unfortunately, I rejected this walkthrough because I went in the wrong direction - through the teleporter near the city, which was guarded by Griffins.
