Couldn't decide on a dynasty weapon for Antosha. If you're playing a specific hero specialization, then maybe it's better to give him "Iron Quill." With that, griffins should be considered beasts + reputation tears + "Retaliation" + "Defense" + Endurance + the "Tears" passive skill "Resilience." And I forgot about reinforcements. Then, as tanks, griffins will be very effective. Also, healing spells, a predisposition to magic, and the whole package.
I gave him the Griffon Sword myself (which is also good). I just set the goal to max out this sword as the first one obtained in the game.
