No matter how many times I've played Heroes 5 and different races against each other, I've come to one conclusion. The strongest race in the late game and on large maps with 3 heroes is the Necromancer. Specifically, Lucrecia with her vampires and the right build. With 20-30 vampires, almost all neutral creatures can be defeated without losses (strong and very strong neutrals, maximum AI difficulty, and a patch for improved AI). Once I have 150+ vampires (I don't even convert vampires from other factions' castles for realism), I reassign the remaining units to another hero because the vampires can handle it on their own. At first glance, the seemingly useless basic spellcasting skills allow you to cast spells on the enemy to apply buffs and debuffs, such as slowing them down. And if you manage to find spells like vampirism, blindness, or mind control, it's even easier. The only opponent I found truly difficult was a hero specializing in elven archers; if I didn't cast Dark Pact on the elves and their turn came before mine, they practically one-shot the vampires. Another unpleasant matchup was against heroes with Divine Retribution and high-level Light Magic and Sorcery, but it all depends on the number of vampires, and if there are many, regeneration compensates for everything. All other combat magic loses its meaning, even if you have 30 Sorcery. Mages with artifacts? Well, I don't know; yes, I've been shocked by the stats of their artifacts, especially initiative, but because the creatures themselves are weak, and the hero has a weak defense bonus, they die faster. All 7 squads (even some attack twice when their turn comes; the vampires attack and regenerate). In the worst case, I remember that I still have 6 squads of untouched undead. As for real opponents, no matter how many times I've played, everyone has acknowledged the power of this late-game build. But, of course, you also need to know how to play this hero. You need to know what to upgrade, which units the vampires are converted from, and spend all your resources only on them, level up other Necromancer heroes for resources, and much more, taking into account all the tricks used by tournament players.
