After playing some slow, tanky, methodical builds this league I really wanted something fast that exploded the screen. Hexblast does absolutely ludicrous damage (~1750 avg with a 310% effectiveness of added damage) and, since we want to scale Area of Effect for better clear, it combos incredibly well with the well establisted combo of Curse on Hit + Profane Bloom + Herald of Ash to explode multiple screens of monsters at once.

The purpose of this build is primarily mapping but it can do all non-uber bosses very easily and can take on a few of the easier ubers [if you invest into spell suppression] without too much struggle as well due to being ranged.

What I present here is a sketch of a build with explanations in the video for how to build it out and what to focus on as you craft the gear for it.

This build scaffold can be be started on a relatively slim budget with Hands of the High Templar and a 3-4D easy to craft bow and scaled to multiple 10s of millions of dps if you want to push it to insane levels.

There is some bonus tech I'm playing around with using Phantasmal Hexblast that I'm still working on but I wanted to share the build as I have it now.

Cheers!

(For folks that don't know the DPS numbers for Blast Rain CoC in PoB aren't accurate so don't judge off that, watch the clips in the video, potential max if you uncomment the line in configuration)
