Tactics for Necropolis.

So, I was looking for him on the Heroes of Might and Magic map! And as soon as I found him, I attacked him right away! :) But without the amplifier, it's really bad! :-(

He surrendered immediately after the battle! He said that he almost defeated me with skeletons! :-) He had two stacks of angels! :-( And I had 2 peasants = skeletons :)
