Ele survivor build

I want to make / play a (legendary)survivor, starting in NF, and doing also Prophesies (?).

What build will suit me best?
And how to defeat safely my mirror?

Ya, I'm trying to do that as well, tho I have problems finding good farming places.
As for the mirror, I used guild wiki tactics, they work well, but probably spear + spear skills would work best (doppelganger can't use spears yet).

One place I wanted to farm was Marga Coast outside Yohlon Heaven, mainly because I can easily solo the insects there, the insects are lvl 20 so 100xp per kill, forthermore there is a wandering priest, so Insect Hunt = 2x exp... so 200xp per piece, and there are scrolls, so I can boost the exp very high.
And... there was only one minor problem... the Insect Hunt didn't give me 2x exp :|
So, I'm joining with the request, need a good farming spot for it [with a build would be nice ^^]

Defeating the Doppleganger is easy and safe... Go E/Me, max Domination Magic, then take Backfire and 7 useless spells (like Rust). Cast Backfire on him, stand back, and let him cast himself to death. Or... Max Water Magic and Ice spear him to death.

As for surviving as an Ele... Earth is the way to go. There's some amazing defensive skills in there, like Stoneflesh Aura, that can make you a very tough target indeed. If you truly want to do nothing but survive, then try:

E/D - high Earth Magic, decent Earth Prayers and Energy Storage.

--> Stoneflesh Aura
--> Armour of Earth
--> Kinetic Armour
--> Stone Daggers
--> Conviction
--> Mystic Regeneration
--> Ether Renewal (E) <--? not sure
--> Res sig

Haven't tried it... but it looks good.

EDIT: Double post

Yeah. I took Backfire and Ice Spear, and whatever other skills were on the skillbar weren't used by either side.

There is a little problem: charachters from Nightfall don't get the 50k exp from killing the mirror.

As for the farming place to go I'd take Trolls outside Droknar or Minos at the beginning of Elona's mission.
