Shadowfrost

Shadowfrost refers to a type of magic wielded by Priests. It means, alike Frostfire, that a spell can do either of two types of spell damage. As the name implies, Shadowfrost does either Shadow or Frost spell damage. Shadowfrost is special as it combines the strengths of these two elements - if an enemy is invulnerable to Shadow, it will deal Frost damage and vice versa. The only spell that uses it so far is Mind Spike.
