How to AOE Grind as a Frost Mage
Follow these simple steps;
1. Find your spot and locate large groups of mobs that ideally aren’t casters.
2. Aggro all of them (a mount will make this easier) and Frost Nova the group.
3. Run till you are at max range and begin casting blizzard until the mobs are low.
4. Once they are low you can use Cone of Cold or Arcane Explosion to finish the pack off.
5. Drink up and rinse/repeat.
