Earth Shattering (Elementalist)
Making it Elementalist/Monk will give you some added help if you want to try and figure out a good way to heal or attract enemies around you for the 2 surrounding dmg spells in the build

Skill Set

Obsidian Flame (118 dmg and only 5 energy BUT exhaustion)

The Flaws:
- Very little self healing.
- Some skills do rely on having enemies surround you
- During long battles exhaustion will make you nearly useless for your team
Other than that this is probably one of the most damaging builds Ive ever used and it generally farms faction quite well.
- Interrupt Rangers could ruin this almost entirely but Stone Daggers, and Crystal Wave require no charge, also Armor of Earth will stop most damage from them.
-Interrupt Mesmers have a 9 second wall of freedom on you, as with any other caster. After the 9 seconds Obsidian Flesh shuts them down again.

The Strategy
Most commonly the battle begins everyone runs out and they stand there till someone runs out to the other team. When someone begins to run out whether if be your team or the others cast Earth Attunement because it reqs a charge time of a few seconds. Follow up with Armor of Earth. Now if you have to run to the enemy you will be slowed by 12% but not the possible 62% had you cast Obsidian Flesh first. Run to the enemy of choice. Hit Obsidian Flesh so you won't be interrupted by mesmers and other casters won't be touching you. Armor of Earth keeps the warrior pissed off so they wont be on you either. When beside the enemy they know its coming so throw Whirlwind and immediately use aftershock. After that spam with Obsidian Flame, when its recharging use Stone Daggers. Wash, rinse and repeat.
