The ninth stage of the Kanigem Tournaments

Man, you're so far ahead of my level:smile20: :smile20: :smile20:. I can't even beat it from the starting save (yet). How much time did you spend on this battle, approximately?
P.S. I'll buy some beer this week and try again, see what happens.

From the starting save, make sure the Nightmares can't inflict Terror even once, and that they lose it. Paladins block the Nightmares' magic with their shields, and it dissipates. At the same time, use the "skip turn" action for all your units; this will allow you to effectively take two turns in a row with all units to move into a good position. Also, try to beat the battle starting from the "checkpoint" save. The difficulty lies in preventing the attacking Nightmare from hitting the Squire. The Nightmare unit tries to attack the Squire when there are only 1-2 Nightmares left in the unit. To prevent them from attacking, make sure your hero's health is NEVER full; you can use save-loading to achieve this so that the Nightmares don't hit the Squire (however, you need to time it so that when a fresh Nightmare unit attacks, your hero's health is full). And if the Nightmares do kill the Squire, in the next part of the battle, your hero will be attacked by TWO Nightmare units, and regeneration won't be able to keep up, but you can probably still win the battle in this case, but then you'll have to have the Regeneration skill spend mana on healing your hero, which isn't ideal for further progress on the map.
P.S. It took me 1.5 hours to complete the battle, including the time spent finding a suitable battlefield, but I think I was lucky that I found a good spot relatively quickly.
