King's Bounty: Armored Princess

There used to be a good combination: griffins, dryads, and demonologists call for reinforcements (the latter can also resurrect units in a pinch), assassins poison (once or twice, it depends on luck), and archers set things on fire (especially under the control of Agvares, although after I lost a bunch of assassins with him while playing as a paladin, I swore never to give him non-shooting units again). Now I had to replace the demonologists with elf archers and plan to hire darklings instead of assassins (the griffins' morale might drop, but I have an artifact that gives them a bonus to it, so let them). It's still difficult to pass levels with the Warrior without losses, but I've already earned a third-level strategist, so I'm not worried. Now I'm thinking about how to get more rage.
