These were water elementals. They cast spells (ice bolt and ring of cold). You have unicorns with an aura that protects against magic; place archers next to them, and you might get lucky! ;)

Water elementals are terrible! In Heroes of Might and Magic IV, they were incredibly useful! But here? Just one Frost Ring, and then the mana runs out! What kind of caster is that?
