Sylvan vs. Necropolis

Another argument against Chaos. Knowing that all spells depend on the magic parameter (and for elves, it hardly increases and depends on the number of elder druids), how will we cast Chaos spells with weak magic if the Necromancer sends our druids to the afterlife?

It's simple here. Take Wing and Sharp Mind. Or you can do without Sharp Mind, but the main thing is that the druids at least go once. Necromancers, as a rule, don't have time to kill them with liches on the first try. But if the druids manage to create a channel, then all the undead are likely doomed. And magic can be easily gained through artifacts, and there's also education.
In general, I'm a bit strange in this topic; I'm more interested in how to kill elves with necromancers, hehe.
