Quill Rain Poison Assassin Ultimate BuildPath of Exile [3.4]: Delve contains ten power-packed skills that are either new or fully reworked and are focused around two character archetypes: the Guardian and the Pathfinder. You can play as a holy warrior thrashing down foes with swift damage while benefiting minions and teammates. Or you can play as a messy archer who makes use of poison and nature-based skills to pin and smother foes.

Whichever class you wish to play in Delve League, whether Duelist, Ranger, Witch, Marauder, Shadow, Scion, Templar, any PoE build is worth trying. Let’s discuss the Quill Rain Poison Assassin Build, which is one of the most interesting ones!

Path of Exile [3.4] – Quill Rain Poison Assassin Build

The Assassin is an offense-oriented class that focuses on critical strikes. It provides improved crits on low or full life foes and improves their power charges.

The PoE build will use Rain Poison as its main skill and probably a single target if you need to throw one in. It will be poison-based and utilize the new Herald of Agony too.

Path of Exile [3.4] - Quill Rain Poison Assassin

Pros and Cons


  • Synergizes well with Poison and Chaos-based damage
  • Uses the new Herald of Agony


  • Doesn’t kill all things rapidly from off-screen i.e. meta PoE builds
  • Doesn’t take the big life wheel hence life on gear is important

Skill Tree

You can buy the PoE items with PoE Currency.


Points – Noxious Strike > Toxic Delivery > Ambush and Assassinate/ Opportunistic


If you kill all, you get Alira or 2 points.

Alira is a good choice always so as to remove some resist pressure from gear; the crit too is a bonus to the PoE build.

As always, when it comes to gear in PoE, you should aim for the resist cap and more than 4.5k life pool for those inevitable big boss hits and one-shots. After that, you should aim for damage and a defense system of your choice. So far, this build still uses some evasion with acrobatics and phase acrobatics.
