Cyclone Armor is a protective barrier created by swirling winds that shield you from the elemental damage of Fire, Cold, or Electricity. If you find yourself in an area where you're taking an excessive amount of elemental damage or you don't have much elemental resistance, Cyclone Armor will bail you out nicely. At level 1 this skill absorbs 40 points of elemental damage, and with each successive point you put into it, you'll endure an additional 12 points of elemental damage. This skill is useful in any circumstance, but is absolutely critical if you're short on amulets, armor, or rings that provide resistances. [1]
