Campaign 6. Mission 4.
Capture Isabel and stop the ritual.
Zehir, Godric and Findan must survive.
In this mission you should focus on Godric, as he has the shortest way before him and the most opportunities to hire new troops. First you'll have to eliminate the light-blue player, so he doesn't interrupt.
Godric and Findan are for now separated from Zehir. Visit all the recruitment points with them and capture the city to the West (1). Meanwhile, use Zehir to capture the one to the East (2). South of it, there's a huge Academy recruitment point. Now use Zehir to destroy the Eastern garrison (3) and Godric or Findan to destroy the Western one (4).
Raelag and Shadia (green) appear to the North-West.
Zahir's next quest will be to capture the blue castle (5) and the others should take care of the one to the South of the center of the map (6). When you capture the fourth castle, the light-blue player is out. The paths meet above those towns, so your heroes can finally meet.
Now Godric will take the brown post (7). Behind it there's an upgrade point, a lookout point and a brown Haven-type city (8), worth capturing. Expand the city and take the troops from it. To get some additional funds, have Zehir use the road along the Eastern border of the map. He'll reach a teleport which will lead him to two spots full of gold.
There's a road from your newly acquired Haven city to another post (9). Go further to find the next city (10), which should be claimed by Godric. The way to the North-West is leading straight to the place where the green player is (11). All that's left is to defeat the dark-blue garrison defenders that are blocking the way. Approach Raelag and Shadia, but don't attack them. A cut-scene will occur, and they will join you. They don't have to do anything particular, just use them to capture some more mines.
Raelag and Shadia must survive.
Go West of the meeting place to find the last garrison, and behind it - Isabel's castle (12). Godric should defeat her in battle, thus ending this scenario. It's good to destroy the castle's defenses first. If you lack units to be successful here, capture some more of brown player's cities.
Campaign 6. Mission 5.
Heroes must survive.
This mission consists of consecutive battles for all your heroes. There are no recruitment points here. The key is to *save* units. On higher difficulty levels it's best to repeat a battle each time you think the losses are too great. Make use of all of your assets here.
At first each hero will have to defeat the nearby garrison's defendants. You want to minimize your losses here. Everyone will meet in the center of the map, where Biara is hiding. It doesn't matter which hero you use to attack the city, every one of them will have his turn here. When you win, you'll be teleported to a one-way path to Demon Lord's castle.
Confront the Demon Lord.
There's a castle at the end of the road - spot the mana regeneration point nearby. The situation is the same as before, all of your heroes will fight in this one. Focus on destroying the magical barrier using the catapults or any other means necessary.
The last series of battles is of course against the Demon Lord himself. Try to finish him off as soon as possible, as he has some powerful massive damage destructive spells. This time you don't have to save your units, as it's the last battle you'll fight in the campaign. Isabel is free, hazza for you.
