I promised someone an Elementalist guide. Right now, this is the best way to play any Elementalist out there.

1) Get level 100 Elementalist.
2) Get Incantatus Staff:



Gratz, now you can oneshot everything up to Fearless!

3) Get Manticore or Son of Ramat boots:



Gratz, now you cannot die up to Fearless!

4) Now use only non-bugged skills that take full bonus from your Staff like Energy Bolts, Icicle Swarm, Stream of Bolts, Ray of Destruction or Blazing Barrier.
5) ???
6) Profit.


Pros:
100% Legit, those items are default game design.
Sets can be bought from Pigasus.

Cons:
Sets require level 100.
Pigasus requires lot of money.
It will work only until Neocore decides to finally fix their set items.
