The most useful spell.

Strategy truly begins when you play against live opponents, aiming for victory rather than simply clearing the entire map – that's just min-maxing. Exploiting AI weaknesses is less about tactics and more about technique, relying on pre-honed strategies. There's nothing inherently wrong with this, but for a truly engaging strategic experience, you need a live opponent, not an artificial substitute. Imagine a chess master playing against absolute beginners who barely know how the pieces move (the AI in Heroes), giving them a massive material advantage. Can such a game be called a strategy game? Can you truly hone your skills in a real game in this scenario? By exploiting AI bugs, you can kill unlimited dragons on the Crystal. In general, summoning is extremely useful against a clueless opponent, and, of course, High Magic is essential when playing against "millions" that cannot be defeated through honest means without exploiting loopholes. If we disregard PvE battles as the most boring and pointless, then in PvP, the most important spells are: Light – Vengeance/Hide (for a warrior – Dispel/Wrath) Dark – Dominate/Plague (for a warrior – Berserk/Slow, against a dark mage – Vampirism) Chaos – Meteor (Armageddon for certain tactics) Summoning – Phoenix (for a warrior – Phantom)
