Necromancer - Vanilla Condi Necro - MetaBattle

Skill Variants

Weapons

To play offhand Sword you need to own the Secrets of the Obscure expansion.
Free-to-play players are going to have to play Scepter/Warhorn instead of Scepter/Pistol.

Utility

Other viable utility options:

瘟疫纹章 - the extremely low CD of this signet could allow you to get away with only playing this one stunbreak. That also makes it easier to make room for other skills on this list.
黑暗法池 - the Blind is great for surviving in melee and the Chill could be used to pressure targets.
增益腐蚀 - unblockable single target boon corruption that's hard to avoid, great for bursting targets without any other setup. It's even good for defensive purposes while under pressure - quickly corrupting 稳固 and 威能 into 恐惧 and 虚弱 for instance could save you.
腐化法池 - AoE boon corruption but less bursty than Corrupt Boon.
腐蚀毒云 - AoE projectile counter and anti-direct damage skill that also helps with killing bunkers with the 中毒.

Elite

召唤血肉魔像 - the idea here is to use a worse elite, but exploit the low CD with 噩梦古物 for another long duation AoE fear proc.

Signet Variant

This is a more offensive version of the build with better boon removal and some much needed 急速 on a build full of slow attacks, but you have to cut a defensive specialization for Spite:

Heal:
Utilities: + either or , 3rd slot is an optional slot (you could also take both). If you pick Signet of the Locust, you might be able to drop the movement focused relic/rune for something else, even if you're not playing Warhorn.
