What kind of magic do you like?

That’s exactly what I was talking about! No matter what the druid’s morale is, the turn-based combat system does its job.
And if we consider the scenario where the druid goes first and casts antimagic on the mantises: then the mage casts spell steal on the druid, or he can teleport right next to him. If on the next turn the druid casts antimagic on himself, he is digging his own grave – when a hero has antimagic, he cannot cast beneficial spells on himself and cannot drink potions. That is, he cannot heal himself and cannot drink immortality potions. Then the mage can cast Mirror Image and simply attack the druid in melee.
