3.8 Toxic Rain Pathfinder + Herald of Agony - All Content - 300% Movespeed

About:
I had originally wanted to make a build that would excel at clearing uber lab while being an easy and fun playstyle. Needless to say I didn't realize how strong Toxic Rain was as a build until I took it into endgame. This build is capable of doing most content even on a 4L setup. It maintains a high DPS and Sustainability due to high amount of evasion, dodge chance, and blind procs. Uber Lab runs are fast and easy due to the 300% movespeed we obtain. This build is capable of all content, though uber elder can be frustrating since we are an evasion/dodge build, we have to play it extra safe.

Playstyle:
The playstyle is very easy, we start by procing our blood rage once we enter a zone. We then proceed to take our left hand and smack our flask buttons ferociously while we zoom through areas while listening to Sonic's Gotta Go Fast theme song. After that, we continue to drop our toxic rain on enemies as we zoom further, allowing the DoT to kill the mobs. Since we play pathfinder, our flask are just about always up making the zooms never-ending.

Pros:
Fast clear speed
Very safe
Cheap to start up
Great at most boss fights
Reflect Immune
Great League Starter

Cons:
No front-loaded damage
Min-Maxing can cost 30Ex+
Evasion/Dodge Based

if youre doing lab runs you should probably use smoke mine and phase run with increased duration. Also herald of agony is kind of awful in lab because it often kills things you dont want it to in the izaro fights. Dying sun is miles better than atziris promise for TR because the AOE and added projectiles both benefit the skill a lot.
