Орден Феникса – харизматический :) лидер

In the game, especially on long distances (and not just on them), it is extremely important to gather skeletons with several heroes, not just one. That is, make sure that the weaker heroes, which you also use in battles to maintain the pace, are also skilled Necromancers. And you are probably aware of the benefits of artifacts that enhance necromancy.

If my memory serves me right, about 4 years ago, a group on VK was collecting something like 500 units for 127, 1000 for 147. I don't know how much that is by today's standards, but I think you have something to strive for)
Well, I played Necromancer here and amassed 241,300 skeletons). So I decided to find out if that's a lot or not, without artifacts on the Necromancer!
Check out the match report for bRitvo4kA vs Sevensan. It's a good example of how skeletons aren't always great. Although this is more of an exception.
