What kind of magic do you like?

Chaos magic. It's the strongest, and its spells hit incredibly well:).

The fact that it has many combat spells doesn't necessarily mean it's the strongest.
But the blessings (buffs for your own units) are really excellent: even just casting "Cat's Reflexes" on your best unit + "First Strike" is much more effective than simply destroying, say, with "Disintegrate" or "Suffocate." :cool:
Although, regarding "Disintegrate," it's a good spell against, for example, vampires, phoenixes, or angels. They also have a very good mass-killing spell. And "Blood Frenzy" and "Hydra's Health" are also not bad. ;)
