This is another map where you rely on Sandro and his ever growing army of Liches for most of the fighting. You also have to be extremely aggressive since the enemies start with towns that are completely built up and the key to victory is to defeat them before they can overwhelm your Liche army. Therefore, take the 5 Vampires as your bonus since this will enable you to attack wandering stacks much more quickly.
I have verified for myself that both Sandro and Finneas won't transfer over to the next campaign even though you are told they will be. Therefore, it's not necessary to visit any Places of Learning or go out of your way to gain levels.
Give Sandro the Vampires and Wights and send him northwest along the yellow path attacking wandering stacks to build up his Liche army. Since Sandro will have such powerful magic, even Death Ripple will enable him to win many battles. You will come across a powerful enemy hero by the name of Nagash who will also have powerful spells but not a big army so your spells will tear through his army very quickly. Once you've taken over O1a (teal), you will have a town that is fully built up and you will be able to upgrade your Liches to Power Liches if you are so inclined. As with the other maps in this campaign, hire a hero and as many troops as possible to protect the town from any enemy heroes that might be lurking about. If you have View Air, check the area for enemy heroes and defeat them before heading south on the yellow path to take over O2a (teal) defeating wandering stacks along the way to increase your Liche army. This shouldn't be a problem and now you can hunt down any O2a (teal) heroes that are wandering about. As with O1a, hire a hero and as many troops as possible just in case the enemy manages to attack O2a (teal) while you're gone. The mirror system will be a big help and once you've defeated the last hero O2a (teal) will be eliminated.
While Sandro is doing this, build a Necromancy Amplifier and City Hall in A1 to enable Sandro to get even more Liches. I took Finneas to O1a and O2a (teal) to give him all of the troops besides the Liches so he can help Sandro exploring and flagging mines.
Now you have to defeat O1b (blue) so you will have some breathing room to visit all of the tents you have to in order to face Duke Alarice to win. Head south to the mirror and then west, defeating all O2b (blue) heroes along the way. Once you've done this, you can visit tents in peace since Duke Alarice doesn't seem to leave his town even though he's able to. There's a Dragon Utopia northwest of O2a which you will want to visit just for the chance of getting good artifacts.
Have Sandro visit G1a (east of O2b) so you can visit G1b and G2a (west of O2a). While you're doing this, take Finneas with a good-sized army to the northeast corner so you can visit G2b and G3a. While Finneas is going northeast, take Sandro through the mirror south of G1b to visit G3b and G5a in the southeast corner. After Finneas is done, have him go west to visit G5b and G6a once Sandro is finished. Now you can get access to N2 by visiting G4a in the southwest corner and have Finneas travel west to G4b and G7a. If Sandro or Finneas is level 25, you can take over N2 if you want to. I was able to hire Nagash who was level 25 but I'm not sure if this will happen to everyone. Taking over N1 or N2 is not necessary but N2 does have a Grail so you might want to do that if only for the boost to your Necromancy skill it gives. Sandro can then retrace his steps, get access to N2, then north to G6b and north to O1b (blue) to defeat Duke Alarice.
