Doppleganger E/Me

i tired alot of things but i cnat beat it i get it really weak but it always gets the last hit E/Mes

Meteor Shower, Fire Storm, a few Flares. Doppleganger is toast in a matter of seconds.

You could spec air and burn him down?

i was a me/ele (suposed theres no diferrence). put most or all your atrributes on domination. use backfire and (i believe shatter enchantment) and empathy. load up on long cating time spells from ele skills ( especially fire storm). took me a while believe it or not to figure out that u can side step the fire storm "the". after i figured this out it took ~10-15 secs for him to die.

i found the easiest thing was maelstorm, put that on him first and he'll just stand there and die
