-Updated for Patch 3.11

 

Blade Vortex is a Physical Spell that creates multiple ethereal blades that orbit around your character dealing massive damage based on the number of blades spawned. This build offers Millions of Poison DPS thanks to massive Poison damage scaling and numerous stacks applied by 10 Blades flying around you damaging enemies with a greatly increased Hit rate. At the same time, this build offers very solid defenses based on Dodge, Mistwalker, and a reasonable Life pool. This is one of the most powerful Assassin builds in the current Patch 3.10, and supposedly the most cost-effective one. You don't need to spend tons of Exalted Orbs on extremely expensive Cluster Jewels and specific Uniques to make it work.

1. Gameplay

This is a very swift Spell Caster build based on the Blade Vortex Spell which deals purely Physical and Chaos Damage in this build as you aim to get the highest effective Poison DoT. You are going to use Unleash Support that helps you build up 10 stacks faster, and when you got it simply rush through Maps recasting Blade Vortex once in a while. You can also use Plague Bearer for some additional DPS against Bosses on tougher Rares - the damage reduction won't really affect your clear speed as you are overkilling the majority of the content with your Poison, and when popping it against Bosses it will help you melt them faster. It's just a single socket too. For the defenses you will be reliant on Dodge and Elusive, you can also pick up Withering Step to get you some extra temporary bonuses (sadly, it shares its' cooldown with Flame Dash so you won't be able to use it efficiently on regular Maps)

This video was recorded on a level 93 Assassin dual-wielding Cold Iron Point Daggers. It offered over 12 Mil Shaper DPS on a very reasonable budget, making it one of the most cost-effective builds we have played so far. This video was recorded in 3.10, however, the gameplay hasn't changed since

3. Leveling tips

You can level up this character easily with Blade Vortex. As an Assassin, you will need to add up some Mana Regeneration mechanics on lower levels, but DPS-wise you will be more than good to take down all the Bosses in campaign mode. You can also help yourself with Agony Crawler from the Herald of Agony. You may have trouble with Mana and Attribute requirements of Malevolence, so you can add a few Support gems to Herald of Agony, which will get you a deadly Minion, and with Blade Vortex and 100% Chance to Poison, you will build up Virulence stacks pretty easily.

Suggested leveling Gem setups:

Blade Vortex setup
Blade Vortex Blade Vortex - primary Spell used in this build. It has solid base DPS and it should carry you through early levels just with its' based damage, and you will still Poison enemies with it
Faster Casting Support Faster Casting Support - on lower levels makes casting Blade Vortex much faster. Later on, you can replace it with Unleash Support which will summon few Blades with each Cast
Poison Support Poison Support - grants high chance to Poison enemies, which combined with a few Passives and Herald of Agony will easily reach 100% Chance to Poison
Vile Toxins Vile Toxins Support - grants high bonus DPS both to direct Hits and Poison DoT
Herald of Agony setup
Herald of Agony Herald of Agony - this is a must-have Herald Spell for this build, which also happens to be a great leveling weapon with Blade Vortex. Just add up a few Support Gems to it and it will melt enemies 
Minion Damage Support Minion Damage Support - increased Agony Crawler's DPS
Pierce Support Pierce Support - grants Pierce to your Agony Crawler's projectiles greatly increasing your clear speed
Vicious Projectiles Support Vicious Projectiles Support - increases the Physical Damage of your Agony Crawler's projectile attacks
Utility Gems
Flame Dash Flame Dash - the recommended mobility Skill for this build
Despair Despair - the best Curse for Poison builds which greatly increases your damage
Plague Bearer Plague Bearer - if you have enough damage against normal enemies, but lack DPS against Bosses this is a great one socket addition to this build. It will reduce your DPS overall, but you will get an extra burst against Bosses on tougher enemies
