The purpose of this guide will be to explain a very effective way of farming with an Elementalist outside of Elona Reach. All of the hints stated here will be based on farming on the Sand Drakes outside of Elona Reach in the desert. After some practice you should be able to make 1-2k in a 10-15 minute period. Along with the money you will, most likely, get many gold and purple drops. To help you farm faster and more effectively I would recommend wearing full Geomancer armor with a Stone's Eye. The Geomancer armor will help protect you against many of the Sand Drake's attacks, because most of their attacks are Earth based.

Tips and Tricks:
Start with Arcane Conundrum. If you like (I wouldn't recommend this), you can replace Power Block(Elite) with Migraine(Elite), to help with the interruption, but Power Block(Elite) disables all the skills(or spells, I don't know)of that attribute, which can be devastating to an air ele, for instance. This will kill nukers, because they will never be able to cast their spells, considering they don't have glyph of concentration. After you have cast Arcane Conundrum, keep slinging interrupts. To help even more, once you hav interrupted a few spells or so, use diversion, so that the person being interrupted cannot cast a spell again.

If you have the recommended attributes and skills here is a list of the attacks you should use and in what order you should use them to kill a Sand Drake as quickly as possible while using the least amount of energy:

1. Use Stone Daggers four times in a row as quickly as possible.
2. Cast Ether Renewal --> Use Stone Daggers three times in a row as quickly as you can --> Use Aftershock - This order allows you to get the most out of Ether Renewal, if you do these quickly enough and you have the other three enchantment spells on you, you will gain a total of +48 energy and +288 health (without counting the energy gained from Earth Attunement and the health gained from Aura of Restoration).
3. Cast Obsidian Flame
4. Cast Crystal Wave
5. Sometimes the Sand Drake will have a small amount of health left, if so a normal attack or Stone Daggers should finish him off.

Some drops from Sand Drakes include:

1. Bows (common, Clean - Gold)
2. Swords (uncommon, Clean - Gold)
3. Wands (common, Clean - Gold)
4. Shields (uncommon, Clean - Gold)
5. Staffs (common, Clean - Gold)
6. Hammers (uncommon, Clean - Gold)
7. Axes (very rare, Clean - Gold)
8. Elonian Keys (uncommon)
9. Gold (common, 50g-120g)
10. Topaz Crests (common, worth 25g)
