I have killed THOUSANDS of elementals and only seen Aero and Tera once each. I farm the elementals often. Hope this info will help those darned farming druids <like me>
As a 58 druid I will have Virtue / KEI / Regrwoth / form of Howler / Resist Magic / Shield of Thorns / Thorn Coat / see invisible on me. I'll have Upheval and Earthquake loaded, as well as Egress, just incase something goes bad. Apparently the Elementals HATE any kind of wolf form and will automatically agro. pull 10 or 20 at a time and use the "point blank AoE" or even better yet, turn a tank into a wolf and have them pull to you. if you, or the tank you turned into a wolf, is beat on while wearing thorns, a nice shot of "Upheval" should kill most, and the rest will go down with "Earthquake". I farm here for the "Essence of Wind" to make Acrylia Temper and the "Swirling Mist" to make Mithril Temper for high elf smithing.
