Build for ROUND 1: FIGHT

Bsurge would be the "normal, effective build" route.

However, you can just poop out a bunch of rit spirits and win without so much as moving.

Different strokes for different folks.

I hardly have any skills unlocked for my ele so I've been using this build and it's working well so far.

[skill]Searing heat[/skill] [skill]Fireball[/skill] [skill]Rodgort's Invocation[/skill] [skill]Liquid flame[/skill] [skill]Blinding flash[/skill] [skill]Aura of restoration[/skill] [skill]Fire Attunement[/skill] [skill]Elemental attunement[/skill]

16 fire
11 energy
8 air

that build will beat the norn tournament, and the master's solo quest where you fight the blessed griffon.

also running that build with 3 SF heroes, cynn and earth hench with 2 monks is tearing through everything so far. even when I faced destroyers and ended up disabling SF we still tear through them quick although if I knew I was fighting destroyers I wouldn't be using SF. I'm sure things get harder but in the icelands 6 ele's are fun to run lol.

for adventuring I don't bring blinding flash, actually been having fun with "finish him!!" in it's place. good for bosses and giants.

[skill]Lightning Orb[/skill][skill]Lightning Hammer[/skill][skill]Glyph of Elemental Power[/skill][skill]Blinding Flash[/skill][skill]Gaze of Contempt[/skill][skill]Aura of Restoration[/skill][skill]Air Attunement[/skill][skill]Elemental Attunement[/skill]

This build can basically deal with anyone, spam Lightning Orb and Hammer.
Blinding Flash for Warrior, Paragon and Ranger, as well as Bison.
Gaze of Contempt to remove enchantments of course.
Keep both Attunements on, Aura of Restoration is for cover, as well as healing.

Ebon hawk, stoning, ash blast, glowstone, armor of earth, aura of restoration, ele attunement, glyph of lesser energy

Use 3 while target is down. This build can't take Mhenlo.

If you want to do it in a simple and boring way, go E/Rt. This can kill everyone fast without too much hassle.

Pain
Vampirism
Anguish
Shadowsong
Painful Bond
Glyph of Concentration
Blinding Surge
"You Move like a Dwarf"

12 Channeling
12 Communing
Left over in Air

For melee, cast shadow song immediately when you enter arena. Use the Dwarf shout to knock em down and cripple. Cast the rest of the spirits, apply painful bond and presto, they are dead. For casters with exception of Mhenlo (vampirism), start with pain (use glyph for those annoying mesmers and interrupters. Cast two spirits, use dwarf shout and cast third while they are knocked down).

Blinding surge is basically insurance and is usually only needed with Magni i.e. Shadowsong expires before he dies so unless you get him blind again fast, 2-3 hits will kill your spirits and you after that.

Hope that helps.
