Tournament reports for "Clash of Clans" in Heroes of Might and Magic 5: Tribes of the East 3.1.

Round 1
Keepers of a Heavenly Gate vs. "Vampires"

valery (demons, Marbas) defeated Zybr (dwarves, Karl)
valery (dwarves, Inga) defeated Zybr (necropolis, Deidra)
valery (demons, Nibros) defeated Zybr (humans, Iris)

Final score: 3-0 in favor of valery.

In the first game, I had an excellent demon with 21 attack, which simply crushed the dwarf, not allowing him to use some very good runes.
In the second game, the Armageddon's Guild and the Light magic were good, but both magics were offered too late. As a result, I ended up on a suboptimal chaos map, but Inga with the right runes still made the difference.
In the third game, again, a decent demon (although with a more modest attack) left the humans with no chance.

Thank you for the games and good luck in the future!
