King's Bounty: Armored Princess

Auto-translated

I don't understand why people set the goal of completing the game "without losses." Of course, you need to protect your troops, which means saving time and money, but "without losses" means replaying most battles several times or prolonging them. Besides, on the official forum, those who played as mages or, at worst, paladins, completed the game without losses. That is, resurrection requires a lot of mana and... the "Resurrection" spell itself. To reduce losses, Ivanjoi advised me to do the following:

There are several simple principles that allow you to protect your troops. They seem obvious to me, but just in case:
1. You should attack each stack of enemy units with all available forces, taking the retaliatory strike with the least valuable creature or tank. The ideal tank is dragons, which can be quickly healed.
2. For the attack, you need to choose a stack that the other enemy stacks won't have time to reach. You need to block, distract, slow down, blind, frighten, or put the others to sleep. Dryads are very helpful in this regard. Shapeshifters or wolves are also useful.
3. Your arsenal must include: vulnerability, dispel, healing, haste, slow, magic source, stone skin, and fear. Magic is also needed for warriors, especially towards the end: chaos - at least level 1, distortion - level 3, and order - level 3. Max out all of the above spells. Vulnerability level 3 is much more useful than +2 to the hero's stats.
4. There are unpleasant opponents who constantly retaliate or simply have very tough stacks that are scary to approach. You can also defeat them without losses. Summon a stack of thorns, bring them closer to the problematic enemy, let the thorns be killed, and then apply slow or fear to that stack. Then, using the Mirror Image spell, eliminate the entire stack in several stages.
5. Of course, the most dangerous opponent is black dragons, which magic doesn't affect directly. No matter how you try, even with advanced tactics, they will still kill someone. It has been noticed that dragons like to attack two stacks at once. You need to give them that opportunity, preparing tasty "meat" for them in advance. Dragons will try to block archers, and teleport is very useful here. Teleport the archers to a safe place and shoot the dragons from there with dragon arrows.

And demonologists are a new unit in "Princess," made from the necromancer model. They attack with "Fire Skulls," which, when attacking demons, turn into magical damage (to deal full damage). Abilities: "Demonic Creatures" (demons are summoned, which are controlled by the computer) and "Life Thread" (like gargoyles, but can heal any unit).
