You still lead Dark Elves forces. Once more the most important thing is to build a lot of defending towers. The problem is that you have not too many materials and your enemy attacks for all the time. You have to counterattack him very soon to recapture his materials. Use tested set of units (without Shadow Blades and flying units) and attack enemy's camps as fast as you can. But do not forget about defense.
1. The portal to Shal
2. The Headquarter
3. The First Orc's base
4. The Second Orc's base
5, 6, 7. Orc's camps
8. The Orc's headquarter
9. Ice Rocks
10. Fire Rocks
11. The portal to Crystal Forest
12. The portal to Song Glass
13, 14, 15, 16, 17. Journey Stones
On the other side of the portal (1) you are given new tasks: destroy all camps of Orcs in Crystal Wastes, and gather all pieces of Book D'arh. Expand your base (2) and prepare yourself for Orc's attacks. There is a lack of stone so you have to build necessary buildings fast. Gather a larger group of soldiers and storm Orc's base to the West (3). You must not wait for too long because you lose all materials. When you kill the general commanding the camp you can find the first piece of the book. Quickly recruit a few new soldiers and storm the second base (4). You can find there the second piece of the book. Now lead your soldiers in the area to capture new materials. But beware of Orc's counterattacks. Build a lot of towers - your enemy is going to waste his time attacking them. During this time you should destroy the rest of Orc's camps (5, 6, 7).
Quest solved: enter the portal to the Crystal Wastes
Quest solved: gather all pieces of Book D'arh
You are given a new quest: find Ice, Fire and Earth Essence. You can look for it near portals that are opened when you completed the book. But don't forget that there still is the last base of Orcs in Crystal Wastes (8).
It's high time to destroy Orcs completely. Wait for their attack and then counterattack them. A group of 20 - 30 soldiers is strong enough to destroy their camp. Gather your soldiers and storm Orc's camp. When you're done gather all items you can find here. Now it's time to take care of your own business.
Quest solved: destroy all Orc's camps in the Crystal Wastes
Go to the Frost Elementals portal (via Ice Rocks Journey Stone) (9). Follow the path, kill all monsters and destroy Elemental Nodes - that's how elementals appear in Crystal Wastes. When you kill the last creature you receive the Ice Essence.
Now teleport your party to Fire Rocks (10) to gather the Fire Essence. Do it in the same way as you did with Ice Elementals. Choose nodes as your first targets. When you're done the next Journey Stone activates (the Portal to the Crystal Forest) (11). Go there.
There is a series of fights with Fire and Ice creatures waiting for you. Kill anything that is alive. When you're done, the portal to Crystal Forest is opened. Before you go to the Crystal Forest solve a few side quests. Go to Jandrim in Westguard - you have all items needed for forging the Bloodmoon axe. Than go back and check the second portal that appeared in Crystal Wastes (12). Approaches it and you get know where it leads. New quests are given to you: find missing scouts in the Song Glass, and check what happened to Malkuth. Remember that Professor Twiddle is waiting for you in the Song Glass too. Enter the portal.
