Tactics against Necromancers.

YES, Gorgons have always been a powerful force, and Hydras are also quite good, especially with Haste and Blessing. In general, you can win against Necropolis with any city; the main thing is to prevent them from acquiring the Amulet of Undead and to have a Hero that is one level higher than the Necromancer (that's all you need). And most importantly – DON'T MAKE STUPID MOVES DURING THE BATTLE!!!!!!
