Today, I won in HRTA 1.5, playing Necropolis against a Dwarf. I focused on Summoning (Power of Charm, Power of Life, Fire Warriors), Defense (Resilience, Stone Skin), Attack (Ball Lightning, Haste), Education (Magic Attraction, Dark Revelation), and a racial skill that I later forgot to learn from a mentor. I took troops from the first three tiers, taking advantage of the free units. Arantir, level 22, against Wulfsten. The opponent surrendered early because he had bad luck with his build. The dominance of Summoning over a poorly built Light faction was obvious. Even though it's Summoning, it's still better than Darkness, because I suspected that the Dwarf had the "Dwarven Luck" skill and that it's better not to engage with spells like Berserk or Dominate (which I encountered in the guild).
