The build tops out at level 80.

There may be other builds like it, but if not... I am calling it the DEE build.

There are three trees and they are pursued at different times. That's up to you.

Remember, 8 levels to make EE happen. You will want to go purely physical on this build, meaning no light/ice/fire rings/ammys/gems. Essentially, this is a EE/Crit build. So you can use crit modifiers.

Works well with EH+LMP/GMP+Fork+CoC+Discharge+Increased AOE/LL w/voles. Another may be EH+lmp/gmp+fork+faster att+whatever.

For your single target, you will want EH(elemental hit)+Faster attacks+Faster projectiles+LL/IIR or EH/FP/FA+whatever you can make work. Honestly, as long as it is physically modified it wont be a problem.

Gear:

You will want to find gear that emphasizes res/life/crit chance/crit mult/IIR(boots: get run speed.)

Gems:

Helm/legs/gloves: Haste + Clarity + Grace + Reduced mana. (May not be feasible until higher levels.)

Chest: EH+LMP/GMP+Faster attacks+Fork+Life Leech+FP/IIR

Bow: EH+FP+FA(everything after this point is up to you.)

The others? Well that is level 18 CWDT+IC+ID+DT and level 17 EC+LL+MS+CWDT.

Remember: Life leech is what makes you. The rest will break you, without life leech.
