1.1UPDATED- ETHEREAL KNIVES CRIT & MAP GUIDE - ES TANK w/ CHAOS INOC- LVLING INFO + PASSIVES + VIDS

Of course you can use a dagger, if it has sufficient Spell Damage on it, like say a Divinarius or better. As for Viper Strike, if you can get decent Accuracy, it can be used rather well since it's Chaos Damage doesn't depend on dagger damage, just it's Attack Speed - might make an interesting alternative to killing Physical Reflect rares.

Thank you for the feedback, I was very satisfied with his answer because we really needed a suggestion about the dagger. To help, I intend to use at lvl 68 "Rathpith Globe Titanium Spirit Shield", which will increase the damage and ES.
But I see that the maximum of "% Increased Spell Damage" of Divinarius is 70%, that would be enough? http://pathofexile.gamepedia.com/Divinarius
As for "Viper Strike", I'm already using with another char ... I now consider one of the best skills in the game, unfortunately can not be used with "Melee Splash", but I use: VS / Multistrike / Fast Attacks / Increased Duration and Vulnerability
Very good and very funny
Please, I accept if you have any other tips.

Good luck always!

ps.: excuse my poor english

Divinarius isn't bad for a starting end-game dagger, but it's not so hard to find daggers with 90+ Spell Damage. Sadly, Daggers can't get Cast Speed, but you can get a LOT of Crit Chance on them, and maybe some Crit Damage.

Corruption Slicer from here: http://www.pathofexile.com/forum/view-thread/212467
That's a good example for a GREAT dagger. 101% Spell Damage, 99% Crit Chance, 25 Mana, 24% Stun Duration.

It should be enough. Ek is a very strong spell and you don't need to build very offensively for it to be effective. Any spell damage / crit / cast speed is a bonus.

I will be updating the OP with new passive builds once 1.0 hits. It might not be right away but I will try to have them up tomorrow or the day after.

Hi terrex! this is Bakutachi if you remember me, just wondering if you would think this is good for EK? i don't really know much about making builds lol

Updated OP with passives / leveling passives. Will finish my passives later but I need to get the letter K!!!!!!!

OP has been updated with passives for the 1.0 patch. Please let me know if there is something you noticed out of place or maybe a way to maximize it better. I think for the most part it is close to what it was before. You will lose an aura but gain spell damage / es / cast speed and possibly crit.

is this still viable

Yep, I got my build updated at the top and leveling passives. I got a dps increase but I could not fit in a third aura. Even picking up 2x 5% reduced reserve passives it would not work.

what do you think is the best way to lvl as EK?
What weapon is good? bows? for the projectiles bonus?
what are the top 2/ 3 support gems you would use while lvling?
