Magic Resistance – The ability to withstand magic attacks.
Thor (Marvel) has some magical resistance and therefore can go toe to toe with his brother Loki, a mighty sorcerer. In Thor V1 #240, Thor can resist the Eye of Horus and absorb a magical bolt with his magic hammer, Mjolnir.
Talisman not only has magic resistance but the ability to absorb magic directed at her in an attack (Omega Flight #4)!
In Action Comics #873 (DC), which is part of the New Krypton story line, nine magic users take out ten thousand Kryptonians or more or less a thousand plus each. Kryptonians are sorely lacking in magic resistance!
