Necropolis or Castle (Which one is stronger?)

Necropolis.

If you have the Amulet of the Necromancer and the Necromancy skill:
Level 1 (Skeletons are resurrected)
Level 2 (Zombies are resurrected)
Level 3 (Liches are resurrected)
.

No, let's not go overboard – such things are usually prohibited:smile21:

Based on most opinions, the outcome of the battle will depend (mainly) on:
-the number of Vampire Lords;
-the number of Skeletons;
-respawn conditions;
+various interesting random events: Berserk, Sphere of Vulnerability, etc.
In total: on a large map, the Necropolis will likely gather a lot of Skeletons and Vampires, so victory is more likely for them.
On a small map, most likely, on the 2nd or 3rd week, Valkyrie will arrive and shoot them all down:(

P.S. But the way the Necropolis can mess things up on a small map with its "smokestack" is something else!!!:D
