This build is incredibly smooth to level once the player reaches level 12 and gains Poisonous Concoction.
Paste this in the vendor window in-game and it highlights four links, movement speed boots, and items with  Green-Green-Green (GGG) sockets. 
This is called a regex filter, and is imperative to finding important items quickly!

The Pathfinder comes with more than enough defenses to take on all the Non-Uber content on the game with your league starter gear, these defenses include:

Physical Damage taken as Elemental Damage allows you to shift the incoming Physical Damage to an element type for it to be mitigated by sources of Elemental Damage reduction such as Flasks and Elemental Resistances.
100% Flask uptime and Flask Effect investment
#% increased effect of Non-Curse Auras from your Skills, amplifies the effect of the buffs granted by Grace.
Temporal Chains slows enemy action speed substantially, making their animations easier to dodge and their attacks less frequent.
Enfeeble Curses monsters making them deal up to 29% less damage and have 19% reduced accuracy rating.
100% Spell Suppression.
Ailment Immunity.
Reflect Immunity.
Evasion Rating, giving you a chance to avoid incoming Attack Damage.

Impending Doom Support supports self-cast Hex Curses. When the Hex expires it triggers a Chaos explosion. To force the the Hex to expire Vixen's Entrapment are used to trigger socketed Curses when you use a Hex skill. 
With Whispers of Doom notable and Vixen's Entrapment your Curse limit is set to 3, so if a 4th Curse is applied it overwrites a Curse, forcing Doom Blast to trigger. 
Because of this interaction you must be wary of how your gems are socketed into your Gloves. 

The top left most socket is the Curse you overwrite, and does not affect the monster, therefore you must choose between Punishment or Enfeeble depending on whether you want more damage or survivability. 
Since this build is a Poison build, it requires Poison Chance to inflict the damaging ailment. 100% Chance to Poison must be achieved by equipping a Divergent Herald of Agony. 
Before you can afford the herald, anoint Toxic Strikes.

Cooldown Recovery Rate is a very important stat for Impending Doom Support. This is because it both affects the cooldown of the Curses you trigger with Vixen's Entrapment and of your Doom Blast. 
By default your Doom Blast triggers 6.7 hits per second, but with more CDR and cast speed you can increase this.

Spell Cascade Support must be socketed in both your Gloves and Body armour to overlap your triggered Hexes on top of your self-cast Hexes. 
The cascading Hex areas create zones where the circles overlap allowing you to hit a single target twice per cast when your mouse is placed slightly behind it.
