Defensive gameplay and other tactics.

By the way, I recently discovered another trick while playing as a Necromancer. I had to accept a battle with a limited mana supply. As a result, I decided to try a new combination. Specifically, I cast Spirit Link on the most dangerous enemy stack. Then the battle continued, and as soon as I ran out of mana, I cast Divine Retribution on that stack. It killed everyone! In this way, I restored about 50 mana at once. And if you think that Light magic is unnecessary for a Necromancer, you are greatly mistaken; it is as necessary for him as summoning.
