The most useful spell.

Chaos Magic: Meteor Shower. Combined with "Emerald Boots," it can obliterate a huge number of enemy units. Light Magic: All spells from the first three circles. From spells above the fourth circle, I would choose "Antimagic." Because it provides excellent protection against powerful magic. Dark Magic: All spells from the first three circles. From spells above the fourth circle, I would choose "Dominate." Capture the best enemy unit and have it attack other important and dangerous enemy creatures. Summoning Magic: Summon Phoenix. This is a monster of victory if there are no Cave Lords, Death Knights, or a hero with the "Deadly Chill" skill in the army. One strike can kill a huge number of low and medium-level creatures. The only drawback is its extremely high cost.
