Магия "Might & Magic Heroes VI"

Teleportation (over a limited distance), retaliation, and a blinding ability are present (although I might be confusing them with radiant spells; they are subconsciously perceived as almost the same unit), as well as various vengeful shields (when they are attacked, the attacker receives a portion of the damage back, and when they die, all enemies around them receive additional damage). When fighting against them, it's hard to imagine a worse opponent (except perhaps phoenixes), as resurrecting all those they have killed is quite difficult.
