The castle is mine ! Lich is a great unit to weaken the defense of a castle before the main attack. Several of them killed many units after the castle archers ran out of arrows including the human ranged hero.

Next castle is under the siege.

Next turn the castle will fall !

What a massacre! Lost 7, killed 159, although half of them were undead...

Main battle of the castle assault - Lich were countered by priest this time, orcs died before managed to climb high walls...

What seemed to be an easy victory, turned into a serious battle. The main damage was done by 3 archers with Human Slayer skill.

I will just leave it here :)
